| run 950127 Physics operator: I. Hutchinson Engineering operator: V. Bertolino Session leader: B. Lipschultz mini-proposal #'s 69/39: Effect of divertor geometry on detachment During this run we continued some of the discharge development of MP# 69 by making the flat-plate and slot- divertor geometries more accessible to the scanning probe. As part of this development we also investigated the detachment characteristics of flat-plate and slot geometry divertor plasmas. We started with the flat-plate geometry, trying a number of different densities. After that we switched to a slot-divertor configuration at 600 kA. The run was very successful in producing the first high density shots with flat-plate geometry and obtaining scanning probe data with these plasmas. In particular we found that the first signs of local detachment occured during shot 17 for nebar= 2.85e20 (nl04~1.5e20). Te in the region of rho=2-3 mm dropped to values of 2 eV. We are fairly confident in the EFIT mapping because between rho=2 mm and rho=0 Te is higher (5-6 eV) and then abruptly drops again crossing into the private flux region (to 1.25 eV). Unfortunately we did not notice that the density was being ramped as the separatrix was being swept across probe 8. This means that we have not exactly determined the 'threshold'. The densities quoted above corr. to the time when the local Te drop passes probe 8. The threshold for localized pressure loss is clearly higher than either inclined plate (nebar_threshold ~ 2.1e20) or slot divertors (nebar_threshold ~ 1.7e20). As the density was increased the dip in Te widened to include the separatrix. In shot 18 nebar=3.4e20 when the separatrix crossed probe 8. The only time we were ever able to achieve a more general divertor detachment was when there was a moly injection (e.g. shot 17) and then detachment extended all the way out to probe 10 (seen on Isat traces). There were some other interesting aspects to the flat-plate divertor. We achieved the highest pressures of any configuration so far. This may only be due to the very high densities, not to the geometry. Artur, I am sure, will be saying something about how the flat-plate geometry compares with other geometries in the near future. We also measured the highest probe densities - 3.e21 on shot 20. We only had a few shots for slot divertor. The only result in this area was that the detachment threshold at 600 kA seemed lower than at 800 kA. We achieved a very quick detachment out to rho=8 mm (the nose of the divertor) at around nebar=1.9e20 (more like 2.5 - 2.8 e20 for 800kA). The density rise was too fast to determine when the localized detachment first starts. It could be as low as nebar=1.5-1.6e20 but this needs to redone more thoroughly. Even before the run started we had problems. Apparently yesterday's run (high elongation disruptions) caused probes 9 and 10 on the outer div. to be shorted. We delayed the run so that Brian can go in and try to unshort them. He was successful with probe 9 but not 10. However, shot 1 disruption returned probe 9 to never-never land. shot 1: awful plasma, disruption and probe 9 reshorted. shot 2: another awful disrruption. shot 3: awful shot w/disruption shot 4: Finally a shot that went without disruption. The strike point was swept over the shot from slot through probe 8. We will try and keep the sweep in the range of probe 8 to 10 over most of the shot. nebar~2.2e20. shot 5: kappa got too high and a disruption resulted. shot 6: power supply problems with resylting disruption. shot 7: Power supplies worked, no disruption. Strike point is still not out to where we want it (probe 9) so we will continue to work on it. Nebar~1.8e20. shot 8: Fairly good shot with nebar~1.8 - 1.9 e20. Separatrix is till not on probe 9. shot 9: We have decided to switch off of probe 9 to probe 8 for obtaining the plate plasma profile. This is for 2 reasons: probe 9 has died (we could have used the Isats from the flush probes) and the rxl controller is not letting us reach probe 9. Otherwise this shot is fairly good. We are getting densities of 6-12e20 at different divertor probes as the sepratrix position moves up the plate. Nebar~ 1.9e20. shot 10: fizzle shot 11: This shot went fine with the sweep on probe 8. We will repeat with the scanning probe. shot 12: Probe penetration fine at .85 sec. Argon also went in this shot for the first time this run to allow for Ar penetration studies with the flat-plate. Next shot raise the density and fine-tune the sweep of the strike point. Don't run the probe so far in for the next shot while we change things. shot 13: We achieved the density we, wanted nl05 of 1.5e20. This corr. to nebar~2.25e20. The probe was partially inserted and the profile across probe 8 was good. Also probe 9 (domed) has returned from the dead (maybe on shot 12). We will make some slight changes to the sweep and redo with full probe insertion. shot 14: Also a good shot. Full probe insertion. nl04=1.7e20, nebar=3-3.2e20. Te ~ 5 eV near the separatrix. Detachment maybe at rho=2 mm shown by a local drop (1 mm wide) in Te to 2 eV. For the next shot we will raise the density to nl04 of 2.e20 (nebar ~ 3.0 e20) shot 15: All went well, nebar=3.5e20 (nl04=2.e20) and probe went in partially. The drop in Te in the region of rho=2mm is more pronounced now giving more confidence in a local detachment. hot 16: Also quite a good shot. nebar=3.5e20 (nl04=2.0e20). Again the local drop in Te is seen at rho=2mm. Probe made it to the separatrix. hot 17: nl04= 2-2.5e20, nebar~3.5-4.3e20. Repeat next shot with probe scan. Large injection of moly at .72 sec causes detachment out to probe 10. Te on probe 8 is less than 2 eV from rho=3 mm through the separatrix into the private flux region; much more detached than previous shot. shot 18: We tried to move the plasma down a little for better probe access. This failed. We also got a disruption. The local drop in Te near rho=1-3 mm is repeated. There is only a small peak in Te near the separatrix of 3 eV (1eV around it). We will call this detached out to rho=3mm. Very high pressures in the divertor - 55 mTorr or so. shot 19: Basically a repeat of 18 with an effort to lower the x-point. Failure in this area + a disruption. Same amount of detachment as shot 18. We will reduce the density for shot 20. shot 20: nebar~2.5e20, nl04 ~ 1.25e20. However, the probe is not able to reach this plasma. We will try some modifications of the equilibrium and try again. Also the processed data indicates 3.e21 on probe 8!!!! There may be slight dip in Te around rho=1-2 mm but not below 4 eV. shot 21: moly injection at .32 sec. The plasma is too far from the scanning probe so we will lower the x-point. Otherwise same as 20. shot 22: Scanning probe went in fine. Same density as previous shot, nl04 = 1.35e20. No signs of detachment. We will lower the density for the next shot. The rf group would like a shot with nl04=.7e20. There will be a flat density ves time at this value from .3-.4 sec after which the nl04 will be increased to 1.e20. shot 23: Achieved the prescribed density - nl04=1.2e20. We will have the scanning probe the next shot. No signs of detachment. However Te is 5 eV in private flux region and across the separatrix to rho~ 3 mm, then increases strongly to 20 eV by 6 mm. shot 24: very good shot, scanning probe and all. Divertor characteristics are the same as shot 23. Switch to slot-divertor for the next shot. shot 25: slot divertor from .4 to .6 seconds. After that the strike point sweeps up the divertor plate. nel04~1.1e20. We will change to lower current on the next shot. shot 26: slot up to .6 seconds but with less of a sweep. This shot is detached from the divertor up to probe 8 from .47 sec on. Oops, we forgot to turn the RF off when we switched to slot divertor. The detachment probably would have occurred earlier than the switchoff of RF (.45 sec or so). We will make an effort to pull the plasma under better control and closer to the probe. nl04=1.1e20. nebar=2.e20 and dropping after .8 sec. shot 27: The RF power was a still on this shot (and the resultant Mo in the plasma). 30 ms after the power shutoff (~ energy confinement time) the divertor detaches. We will switch them to late in the shot because the slot is at the beginning. nel04~1.1e20.Nebar~2.e20. shot 28: This shot was better. The probe went in to the separatrix. There was a definite detachment at .4 seconds extending all the way up to probe 8 (~7-8mm into the SOL). Following that the plasma gradually reattaches with Te rising at sequential probes (7,6,5,4,3..) going down the divertor plate; each sequential probe location reattaching with a slight delay after the next. On reflection, this behaviour also occured on the previous shot. |

| Physop Summary 950127 Alternate Divertor Configurations. Horizontal Plate and Slot. PO: Hutch SL: Blip EO: Bertolino OVERVIEW. Early shots, 1-5 were problematic because there was too much gas in the first 100ms. This was evidenced by slow current rise that leads to a lot of flux consumption and railing EF2s. The programming was inherited from the last two days. Yesterday the Ip rise was slow also. The previous day not. The fix was to lower the programmed gas quite a lot. The plenum pressure was high today: 18-20 psi. Conclusion: easiest fix for railing EF2s is to lower the early gas programming. Eventually good horizontal-plate diverted shots were obtained with the strike-point swept out to just past probe 8. (Probe 9 was flaky.) Shots 8 and 9 tried slightly higher EF4 current. They ran into problems at the shot end because raising EF4 lowers EF2 and the EF2 currents zeroed out causing a vertical instability. One idea: Feed back on the EF4 current to keep EF2 at a sensible level. Worth trying sometime. Z-oscillations were experienced in many shots prior to 13. These were finally cured by lowering the Fast ZCUR to PD=(5,6) with slow Zcur at P=3. These are close to the settings advocated on the basis of yesterday's experiments. Shots 17 - 19 were record NeL04=2.5e20. They ran till the end of flat top but were termiinated by VDE. The cause of this was not clear. However, several power supplies were showing signs of being at or near voltage rails because of the large loop voltage (2.2V). This ought to be investigated further if we want to push density. Shots 25-28 Were slot configuration. Owing to PCS Ghosts, 25 and 26 had zero gain on strkpsi so the slot was not held. 27 and 28 were decently held for .3-.7s and 28 was probed with the reciprocating probe. 25-27 were seriously perturbed by RF impurity injections early. RF was off for 28. Shot 28 looks very interesting for detachment physics etc. SCORECARD Shot,Duration(s),Ipmax(MA) Shot,Duration(s),Ipmax 1 0.457 0.784 2 0.369 0.737 3 0.348 0.471 4 1.472 0.828 5 0.401 0.750 6 0.420 0.585 7 1.466 0.833 8 0.965 0.828 9 0.957 0.830 10 0.000 0.029 11 1.412 0.835 12 1.293 0.833 13 1.266 0.822 14 1.239 0.820 15 1.296 0.822 16 1.320 0.820 17 1.285 0.820 18 1.015 0.820 19 0.951 0.817 20 1.393 0.825 21 1.372 0.822 22 1.342 0.822 23 1.401 0.830 24 1.401 0.833 25 1.396 0.830 26 1.354 0.652 27 1.323 0.647 28 1.316 0.639 Finished summary for 950127 Total of 28 shots. 28 shots. 27 plasmas. 1 fizzles. 0 duds. Fizzle = gt 17 lt 50kA. DETAILS Loaded segment 2 from 941220016 a slot divertor. Turned off STRKPSI and turned up RXL,ZXL gains to 35 s^-1 Drew a ramp in RXL from -.01 to +.03 (.4s to .95s). Copied wire 10 (2nd fast ZCUR) from 95012633 but zeroed its gains for now. Density slow ramp to 1.3e20 nel. Fill 1.5e-5. Shot 1 Pla Disrupts at .45 seconds. Very ugly in first .1s. Looks over gassed. Dropped gas valve V early. 2 Pla Better current rise but EF2 rails at .3s and vertical stability lost. Loaded segment 1 from 950125011. Drew RXL in to -.03 at .3s. 3 Pla Railed EF2 and disrupted at .3s Imported segment 1 from shot 2. Lowered the gas still more early. Raised ef2 voltage V to 300V. 4 Pla Just avoided railing EF2. No disruption Found that RXL ZXL gains were not up as they should have been. Turned them up to 36 /s. Lowered Chopper D to 5 from 8. Drew Zcur to -5mm. 5 Pla Disrupts due to vertical instab. EF2 did not rail Chopper to PD=(8,8). Drew ZXL ramp higher in the first .3s Lowered early gas still more. 6 Pla Disrupt at .4s. Whole shot went bad because EF1 PS faulted at .15s. Current rise is now decent. 400kA at .1s. Repeat. 7 Pla Still oscillating vertically but survives. Found something strange at .8s seems to correlate with the reset of C integrator. Moved that later (1.1s) to stop it happening. Drew RXL further out. Drew ZXL to ramp up. Raised gas to 1.4e20. 8 Pla Disrupts at .95s. The .8s lurch appears still to be there. Found that the lurch also coincided with a gain notch on ZXL. Removed. Raised EF4 to 2500 A at shot end. Raised RXL to .045 which is max allowed. And made it earlier. Raised ZXL to .02 at shot end. 9 Pla Disrupt at .96. EF2 currents zero out rapidly. A slow drift in zcur. Brought the EF4 ramp down later. Increased slow zcur P to 2.5 Decreased fast zcur d to 6 Delayed clearin down ramp to 0.95s. Reduced the RXL ramp to +.04 10 Fiz Br seems to have drifted up to .002 Reduced the offset to 6e-3 from 7.e-3. 11 Pla Reduced Fast P to 6 at .4s. 12 Pla Reduced Fast P to 5 at .35s Increased density demand Delayed the RXL ramp by about .05s Ramp down EF4 faster at the end. 13 Pla Z-oscillation gone. RXU to -.035 from -.04 Adjust the RXL ramp slightly lower. 14 Pla Rampdown disruption at 1.22s. Raised nel to 2.e20 Raised gain on ZXL at the end. 15 Pla Repeat with probe in. 16 Pla ECE gate valve closed due to trip. Raised plenum pressure to 20 for 18.5 Raised Drawn nel to 2.5e20 Delayed RXL scan to start at .6s. 17 Pla Achieved demand, but injection at .73s nearly coincident with probe scan. This is a Moly injection, but the Mo monitor was not tuned to Mo. Repeat 18 Pla Disrupt (VDE) at 1.05s. ZXL not well controlled at shot end. Appears that EF1 is on voltage rail. Perhaps due to large required loop voltage. Drew ZXL 1cm down. Flattened EF4 current. 19 Pla Disrupts at .95s. Caused by a VDE. Not obvious why Reload density from shot 950127012 and tweaked. Put ZXL back to .02. 20 Pla Good ramp down. Slight z-oscillations early. Load RXL and ZXL from shot 12. 21 Pla Fine. Too far away. Railing the EF2s at .35s. Lowered the early gas to try to fix EF2s. 22 Pla Got a faster Ip ramp 435kA at .1s. Escaped the EF2 rail. Raised Slow Z P to 3. Put a flatspot on nel till .4s then later value 1.1 Delayed the ZXL ramp, and lowered to .03m. 23 Pla OK as advertized. Repeat. 24 Pla Return to slots Lower RXL to 1., ZXL to 3. Draw -.02, -.003. STRKPSI gain to PI=(6,1) 25 Pla Got a Slot. starts to strike later. Lowered Ip to 600kA Drew zcur to -.01m. Put 2.5kA hump on EF4. 26 Pla RF put in quite a lot of power. Found that the strkpsi gain was zero. Set it again Drew RCUR to -1.5cm Fixed the Ip programming I hope 27 Pla Nearly switched off the EF2s at 0.6s. Still have a slight lump in Ip. Moved the RF to the end of the shot. Call for the probe scan. 28 Pla OK. The current blip is less pronounced. RF effects? |

Physics operator: I. Hutchinson Engineering operator: V. Bertolino Session leader: B. Lipschultz mini-proposal #'s 69/39: Effect of divertor geometry on detachment During this run we will continue some of the discharge development of MP# 69 by making the flat-plate and slot- divertor geometres more accessible to the scanning probe. As part of this development we will also investigate the detachment characteristics of flat-plate and slot geometry divertor plasmas. We will start with the flat-plate geometry, investigate the detachment threshold and characterisitcs. After that we will switch to a slot-divertor configuration at 600 kA and see if we can pull the x-point away from the inner divertor whilst keeping the outer separatrix strike point in the slot. | |
| Jan 27 1995 09:07:00:340AM | 950127001 | Bruce Lipschultz | shot 1: Be fore the run Brian went in and unshorted probe 9 (shorted during
yesterday's disruptions). However this awful shot/disruption reshorted it. |
| Jan 27 1995 09:08:27:170AM | 950127002 | Bruce Lipschultz | shot 2: another awful disrruption.
|
| Jan 27 1995 09:53:23:740AM | 950127004 | Bruce Lipschultz | shot 4: Finally a shot that went without disruption. The strike point
was swept over the shot from slot through probe 8. We will try and keep the sweep in the range of probe 8 to 10 over most of the shot. nebar~2.2e20. |
| Jan 27 1995 10:03:18:610AM | 950127005 | Bruce Lipschultz | shot 5: kappa got too high and a disruption resulted.

|
| Jan 27 1995 10:21:18:340AM | 950127006 | Bruce Lipschultz | shot 6: power supply problems with resylting disruption.
|
| Jan 27 1995 10:48:39:750AM | 950127007 | Bruce Lipschultz | shot 7: Power supplies worked, no disruption. Strike point is still
not out to where we want it (probe 9) so we will continue to work on it. Nebar~1.8e20.. |
| Jan 27 1995 11:14:10:200AM | 950127008 | Bruce Lipschultz | shot 8: Fairly good shot with nebar~1.8 - 1.9 e20. Separatrix is till
not on probe 9. |
| Jan 27 1995 11:37:46:990AM | 950127009 | Bruce Lipschultz | shot 9: We have decided to switch off of probe 9 to probe 8 for obtaining
the plate plasma profile. This is for 2 reasons: probe 9 has died (we could have used the Isats from the flush probes) and the rxl controller is not letting us reach probe 9. Otherwise this shot is fairly good. We are getting densities of 6-12e20 at different divertor probes as the sepratrix position moves up the plate. Nebar~ 1.9e20. |
| Jan 27 1995 11:47:52:960AM | 950127010 | Bruce Lipschultz | shot 10: fizzle
|
| Jan 27 1995 12:17:54:940PM | 950127011 | Bruce Lipschultz | shot 11: This shot went fine with the sweep on probe 8. We will repeat
with the scanning probe. |
| Jan 27 1995 12:21:44:030PM | 950127012 | Bruce Lipschultz | shot 12: Probe penetration fine at .85 sec. Argon also went in this
shot for the first time this run to allow for Ar penetration studies with the flat-plate. Next shot raise the density and fine-tune the sweep of the strike point. Don't run the probe so far in for the next shot while we change things. |
| Jan 27 1995 12:45:36:200PM | 950127013 | Bruce Lipschultz | shot 13: We achieved the density we, wanted nl05 of 1.5e20. This corr.
to nebar~2.25e20. The probe was partially inserted and the profile across probe 8 was good. Also probe 9 (domed) has returned from the dead (maybe on shot 12). We will make some slight changes to the sweep and redo with full probe insertion. |
| Jan 27 1995 12:54:52:190PM | 950127014 | Bruce Lipschultz | shot 14: Also a good shot. Full probe insertion. For the next shot we
will raise the density to nl04 of 2.e20 (nebar ~ 3.0 e20) |
| Jan 27 1995 12:55:18:750PM | 950127014 | Bruce Lipschultz | shot 14: Also a good shot. Full probe insertion. For the next shot we
will raise the density to nl04 of 2.e20 (nebar ~ 3.0 e20) |
| Jan 27 1995 01:20:38:480PM | 950127015 | Bruce Lipschultz | shot 15: All went well, nebar=3.2e20 (nl04=2.e20) and probe went in.
No obvious signs of detachment. |
| Jan 27 1995 01:45:02:590PM | 950127016 | Bruce Lipschultz | shot 16: Also quite a good shot.
|
| Jan 27 1995 01:50:50:820PM | 950127017 | Bruce Lipschultz | shot 17: Record high denaities: nl04=2.5e20. Nebar of order 5.e20.
There was an 'event' at .72 sec which is a moly injection. This induces a definite detachment out through probe 10! We will repeat with the full insertion of the scanning probe. |
| Jan 27 1995 02:17:50:220PM | 950127017 | Bruce Lipschultz | shot 17: nl04= 2.5e20, nebar~4.5e20. Repeat with probe scan. Large
injection of moly at .72 sec causes detachment out to probe 10. Otherwise it is not obvious that the divertor is detached. |
| Jan 27 1995 02:19:09:900PM | 950127018 | Bruce Lipschultz | shot 18: We tried to move the plasma down a little for better
probe access. This failed. We also got a disruption. We will go back down in density for the next shot. |
| Jan 27 1995 02:22:35:380PM | 950127019 | Bruce Lipschultz | shot 19: Basically a repeat of 18 with an effort to lower the x-point.
Failure in this area + a disruption. We will reduce the density for shot 20. |
| Jan 27 1995 02:56:09:240PM | 950127020 | Bruce Lipschultz | shot 20: nebar~2.5e20, nl04 ~ 1.25e20. However, the probe is not able
to reach this plasma. We will try some modifications of the equilibrium and try a |
| Jan 27 1995 03:03:34:530PM | 950127021 | Bruce Lipschultz | shot 21: moly injection at .32 sec. The plasma is too far from the
scanning probe so we will lower the x-point. |
| Jan 27 1995 03:23:18:190PM | 950127022 | Bruce Lipschultz | shot 22: Scanning probe went in fine. Same density as previous shot,
nl04 = 1.35e20. We will lower the density for the next shot. The rf group would like a shot with nl04=.7e20. There will be a flat density ves time at this value from .3-.4 sec after which the nl04 will be increased to 1.e20. |
| Jan 27 1995 03:33:51:910PM | 950127023 | Bruce Lipschultz | shot 23: Achieved the prescribed density - nl04=1.2e20. We will have the
scanning probe the next shot. |
| Jan 27 1995 03:52:09:260PM | 950127024 | Bruce Lipschultz | shot 24: Very good shot, scanning probe and all.
|
| Jan 27 1995 04:06:17:510PM | 950127025 | Bruce Lipschultz | shot 25: slot divertor from .4 to .6 seconds. After that the strike point
sweeps up the divertor plate. nel04~1.1e20. We will change to lower current on the next shot. |
| Jan 27 1995 04:27:36:960PM | 950127026 | Bruce Lipschultz | shot 26: slot up to .6 seconds but with less of a sweep. This shot
is detached from the divertor up to probe 8. We will make an effort to pull the plasma under better control and closer to the probe. |
| Jan 27 1995 04:46:31:100PM | 950127027 | Bruce Lipschultz | shot 27: The RF power was a little high this shot (and the
resultant Mo in the plasma). 30 ms after the power shutoff (~ energy confinement time) the divertor detaches. We will switch them to late in the shot because the slot is at the beginning. nel04~1.1e20. |
| Jan 27 1995 05:56:19:860PM | 950127028 | Bruce Lipschultz | shot 28: This shot was better. The probe went in to the separatrix.
There was a definite detachment at .4 seconds extending all the way up to probe 8 (~7-8mm into the SOL). Following that the plasma gradually reattaches with Te rising at sequential probes (7,6,5,4,3..) going down the divertor plate; eache sequential probe location reattaching with a slight delay after the next. |
