| Session leader summary for Run 931022: Session leader: R. Granetz Physics operator: S. Fairfax Engineer-in-charge: V. Bertolini/F. Silva The objective of today's run was to try to achieve ohmic H-mode in Alcator C-MOD. Because the ohmic power is presently limited to about a megawatt, we wanted to go to as low a B-field and as low a density as possible, since experience on other tokamaks indicated this would make transition possible at lower power. We successfully achieved an unambiguous ohmic H-mode on several shots today (20, 38, 39, 41, 43, and 44). The B-field ranged between 3.0 and 3.2 Tesla at the transition, and the density was about 0.6-0.7 x 10**20 /m3. The H-mode was indicated by L-H-L transitions in the H-alpha, increases in the density, stored kinetic energy (about 25%), tau_E (roughly 50% or more?), and tau_p. Marked increases in impurity accumulation and radiated power were also noted. This run was the culmination of several earlier preparatory runs (low field run, reversed field and current run, etc), and was also partially motivated by a previous shot from a Snipes/Hutchinson run that showed a hint of H/L transitions on the H-alpha signal. Because we needed high current (for high ohmic power) and low B-field, we also tended to run down to very low q, reaching q95=2.0-2.1 on shots 39, 41, and 43 (and possibly causing major disruptions). In addition, the low B-fields reduced the cooldown time required between shots, resulting in an increased rep rate. We had 36 shots during the regulation 9 innings, and an extension to 19:00 came up with 9 more shots in extra innings, resulting in a total of 45 pulses today. However, getting breakdown and current rampup at reduced field proved difficult and fickle, so our batting average was much less than any other run during the previous couple of weeks. A little more detail: We started with a 5.3 tesla, 0.86 MA shot from the beginning of this week (931019001), and achieved it on shot #2. We then lowered the plasma current programming to 0.75 MA, and the toroidal field to 3.5 tesla at commutation, and tried for the next 28 shots to get a reliable breakdown and current rampup. (In addition, the TF was being ramped down further, starting at t=0.5 s.) This proved to be quite frustrating, primarily because the TF supplies go into regulation prior to commutation at these low fields, and this significantly reduces the source voltage available to the Robicon supplies. This means that the OH2's and EF1's don't have quite the necessary voltage to get to the precisely programmed currents required for successfull breakdown and plasma initiation. The TF turn-on can't be delayed much because of an over-stress problem at these lower fields (see Steve Fairfax or myself if you really want to know the gory details). We were fighting the irreproducibility in the power supplies for all of these shots. I think we also had some problems with feedback control on the x-point position competing with feedback control of other parameters as well. Nevertheless, using tricks we learned from our previous low-field run (opposite polarity) we managed to get a couple of halfway decent shots, one of which (#20) had an unmistakable transition to H-mode at t=0.615 s. After ten more attempts (mostly unsuccessful) at getting more discharges at 3.5 tesla, I finally gave up and raised the field at breakdown to 4.0 T prior to shot 31. The next four shots all went (with no changes to the magnetics), although they all ended around 0.5 s, before the B-field had decayed significantly. The OH2's then started drifting again, due to the low source voltage problem. After shot 36, Steve Fairfax realized that at 4 T (as opposed to 3.5 T), the start of the TF could be delayed by 0.4 s, resulting in commutation occurring just prior to going into regulation, and just barely avoiding the low-field stress limit on the TF core. This gave much more reliable operation of the OH2's and EF1's. We decided to extend the run by two hours, and this final series of shots (37-44) were much more successful, with 38, 39, 41, 43, and 44 having H-modes. Most of them ended with disruptions at q95=2.0-2.1. The last shot (45) was purposely a dud, in order to provide background data for the diamagnetic signals and the divertor pressure guage. Box score: 22 plasmas (some on the short side) 14 fizzles 9 duds (one on purpose for background, one due to alternator fault) --- 45 total All-in-all it was a very difficult, but eventually a very satisfying day. My thanks to the engineers and physicists who agreed to stay late on this Friday evening. It really paid off. RSG |

| Engineering Operator Summary October 22, 1993 Session Leader: R. Granetz Physics Operator: S.Fairfax Engineering Operator: F. Silva/V. Bertolino Power Systems: V. Bertolino/J. Daigle Aux. Systems: G. Gerolomo State: J. Orvosh/Andy Pfieffer The objective of this run was Ohmic H-mode. We achieved this on shots 38, 39, 41, 43, and 44. Many fizzles and duds trying to get reliable breakdown at 3.3 Tesla. Eventually, we chose discretion over valor and operated with breakdown at 4 Tesla. We set records for the number of shots in a normal shift (36) and number in a long run (45). The secret is not only low fields but close cooperation and andvance planning between session leader and physics operator. We tried to always have a set of changes for the next shot drawn and ready for loading while still in INIT for the present shot. After a quick look we would either discard the changes or load them and run the next shot. Some of the H-mode shots got to very low q*, roughly 2. The last plasma shot (44) had constant q from 0.5 to 0.8 sec.

Fairfax is back. Both gradient and Bz look high. Increased OH1 prechage from -16600 to -16850 to decrease dBz/dr, and changed EF4 from -1030 to -1075 to decrease Bz. Shot 18 Plasma. Disrupted at 0.4 second. dBz/dR changed slightly more than we calculated. Nulls aren't pretty, but it worked this time. Changed Ip demand from 0.8 ramping to 0.9 MA to 0.7 ramping to 0.8 MA.

On advice from Steve Horne, changed wire1 (slow zcur) prop. gain from 1 to 0.5, int gain from 2.0 to 2.5.This should help with z position oscillations later in shot. Shot 23 Plasma. Disrupted at 0.46 sec. No changes. Shot 24 Fizzle. Set gas to 1.3, TF invert to 0.3. Fileds are strange Shot 25 Dud gas to 1.4 Shot 26 Fizzle changed OH1 to go 1 kA high then ramp back down before t=0 Shot 27 Fizzle almost went, breakdown at 7 rather than 12 msec. asked alternator to set output voltage at 13.5 rather than 13.0 kV. Delayed gas start by 2 msec from -11 to -9 msec. Shot 28 Dud. decreased OH1 prechage from -16800 to -16600 to increase dBz/dr, and changed EF4 from -1075 to -1030 to compensate effect of OH1 change on Bz.

Shot 32 Plasma Same as last time, disrupted at .47 seconds. removed jump in x-point control gain at .384 seconds Shot 33 Plasma Slightly longer, but no real help. Set TF inversion to 0.2 sec. Increased pulse gas from 0.3 to 0.4 sec from 38 to 45 volts Shot 34 Plasma Still disrupted at .43. Changed knot on RXL to start pushing it down at 0.5 sec rather than 0.4 sec.

Delayed start of TF by .4 sec Shot 37 Plasma Density low, 2e19. change gas at 77 msec from 31 to 38 volts Shot 38 Plasma Messy H-mode. Hit OH1 PLC limit. Because we have changed the TF, this limit is now too conservative. Raised OH1 reverse current limit from -9 to -11 kA. Shot 39 Plasma H-mode. Disrup[ted when we hit OH1 current limit. Turned off gas puff at 0.5 second. Set OH1 current limit to 12 and set Ip progam to begin ramping down Ipat 0.8 seconds. Reduced gains on Rxl, Zxl, and Clearin during plasma ramp-down. Shot 40 Dud. Alternator trip early. Shot 41 Plasma Disrupted at .74 seconds. Lowered gas puff and turned Ip down earlier. Set OH1 invert time to 1.1 from 1.3 seconds. Shot 42 Plasma Disrupted at .5 second. Increase gas puff. Set OH1 limit to 13 kA Shot 43 Plasma Disrupted at .58 seconds. Changed Ip program to hold constant q from 0.5 seconds on. Shot 44 Plasma Disrupted at 0.85 seconds. Removed Hybrid enable from pulse gas and argon, set reverse current limits to -5 ka OH and -2 kA EF1 fill pressure to 2e-4 Shot 45 Deliberate Dud. Suggestion for future: close diagnostic valves BEFORE the torus pressure does. Steve Fairfax |

| Oct 22 1993 09:03:19:100AM | 931022001 | Robert Granetz | Fizzle. OH2 PLC current limits were mistakenly set for 20 kA
(actually -20 KA), and they should have been set for 25 kA. Try this shot again with the proper PLC limits. |
| Oct 22 1993 09:19:38:390AM | 931022002 | Robert Granetz | Got a reasonable shot, but it ended in a major disruption at the beginning
of the rampdown (t=0.93 s). Ip=-0.87 MA, Btor=5.3 T. Density was acceptably low, nl_4=0.3-0.4 e20 /m3. For the next shot, lower the toroidal field to 3.5 tesla (Itf=101 kA) for the entire shot. Try to get breakdown. |
| Oct 22 1993 09:41:52:820AM | 931022003 | Robert Granetz | Fizzle. Not bad for the first try at 3.4 T.
The field null plots look like they have a small problem near EF1L. This coil had 200 amps less current than requested. For the next shot, increase the requested current by 200 amps (Steve Fairfax doesn't understand EF1L's behavior, so we'll just try this simple kludge first.) |
| Oct 22 1993 09:52:12:170AM | 931022004 | Robert Granetz | No breakdown. Fields actually looked pretty good. Change feedback gain
on EF1's and try again. |
| Oct 22 1993 10:05:10:310AM | 931022005 | Robert Granetz | Got a plasma, but it ended early in a major disruption at 0.37 s. Plasma
current reached -0.74 MA. The current rise was pretty clean, believe it or not. I don't think there was an impurity injection. It turns out that q*=2.5 and q95=2.7. Density was also a bit low, leading to a few non-thermals on the ECE. For the next shot, just do a repeat with no changes. |
| Oct 22 1993 10:24:36:450AM | 931022006 | Robert Granetz | Short, ugly. Ended at 0.13 s. No obvious reason. Try again, with a little
more early gas puffing. |
| Oct 22 1993 10:26:40:080AM | 931022007 | Robert Granetz | Disrupted at 0.38 s. Very similar to shot 5. The plasma position is
at R=0.69 m, and it is riding against the RF limiter for the whole shot. For the next shot, move the plasma in by two centimeters (R=0.66 m). |
| Oct 22 1993 10:36:09:520AM | 931022008 | Robert Granetz | No breakdown. For the next shot, increase pre-fill from 1.3 to 1.4e-5 torr.
|
| Oct 22 1993 10:47:00:120AM | 931022009 | Robert Granetz | Fizzle. For the next shot, increase vertical field by 1 mT using EF4.
|
| Oct 22 1993 11:05:29:450AM | 931022010 | Robert Granetz | Another fizzle. Principal change between shot 7, which worked, and the last
several fizzles was the programming of RCUR to be 2 cm earlier. The feedback on this turns on at 0.010 s. So maybe that's it. Change RCUR programming back to what it was prior to 0.1 s, and then shift inwards 2 cm. Also return EF4 (Bz) back to what it was prior to this shot. Also lower pre-fill back to 1.3e-5 torr. |
| Oct 22 1993 11:23:10:260AM | 931022011 | Robert Granetz | Well, it's better, but still short. Major disruption at 0.24 s. kappa got
up to about 1.55 when it disrupted. Zcur is was programmed to drop to -3 cm. Change this to -2 cm for the next shot. It appeared to be a vertical instability that got us on this shot, but EFC didn't fight it. |
| Oct 22 1993 11:42:52:850AM | 931022012 | Robert Granetz | Identical to the previous shot. Plasma gets into trouble start right
at 0.200 s. This is exactly where the CLEARIN (inboard clearance) feedback turns on (abruptly!). Delay this to 0.3 s for the next shot. |
| Oct 22 1993 11:47:14:850AM | 931022013 | Robert Granetz | No breakdown. Raise pre-fill to 1.4e-5 and try again.
|
| Oct 22 1993 12:03:02:430PM | 931022014 | Robert Granetz | No breakdown again. Vacuum nulls look really good. We don't understand
how we couldn't even have gotten a breakdown on this shot. Increase pre-fill to 1.5e-5 and try again. |
| Oct 22 1993 12:15:57:940PM | 931022015 | Robert Granetz | Got it back, but it was short. Ended with a major disruption at 0.34 s,
but the OH2's (which are involved in CLEARIN feedback) started misbehaving at exactly 0.30 s, which is where we moved the CLEARIN feedback turn-on to. We think it's a problem with fighting between the CLEARIN and ZCUR control. This has changed because we programmed RCUR to move in to 0.66 m today. For the next shot, move RCUR out by one centimeter to 0.67, and move the RF limiter out from 0.93 to 0.94 m. |
| Oct 22 1993 12:28:28:120PM | 931022016 | Robert Granetz | Fizzle. No changes were made early in the shot, so just do it again.
|
| Oct 22 1993 12:42:15:140PM | 931022017 | Robert Granetz | Fizzle again. I guess the null needs to be tweaked. Steve Wolfe has
complained that the field gradient is to high, so Steve Fairfax has reduced it by -0.010 T/m by subtracting 250 A from OH1. This will cause an increase in Bz by 2.5 mT, so the current in EF4 has also been changed by -45 A to compensation. |
| Oct 22 1993 12:59:14:040PM | 931022018 | Robert Granetz | Got it back. Disrupted at 0.40 s, when q* gets to 2.5. I think the null
looks worse than before. The dBz/dR gradient changed a little to much, but I'm not going to worry about it for the next shot. Limiter clearances looked good after 0.1 s. For the next shot, reduce the plasma current by 100 kA. |
| Oct 22 1993 01:16:05:430PM | 931022019 | Robert Granetz | Better. Major disruption at 0.50 s. Ip=-0.73 MA. The TF starts its
rampdown at 0.50 s. Density is at the low end of the normal range, nl_4=5e19. The elongation is quite high...FFIT says kappa=1.61. For the next shot, reduce the current during the first half of the shot by 50 kA, but let it still ramp up to 0.90 MA late in the shot (if we ever get that far). |
| Oct 22 1993 01:35:47:430PM | 931022020 | Robert Granetz | Possible H-mode! Major disruption at 0.67 s. Ip=-0.72 MA. Clear H-alpha
drop at 0.615 s. Rate of density rise clearly increases at the same time. For the next shot increase RCUR by 1 cm, since we now seem to have plenty of clearance. This might help keep the kappa a little lower. Jim Terry reports that this is not a detached plasma. |
| Oct 22 1993 01:36:27:670PM | 931022021 | Robert Granetz | Fizzle! I don't believe it. Try again, with the only change being a decrease
in the pre-fill from 1.5 to 1.4e-5 torr. |
| Oct 22 1993 02:03:12:520PM | 931022022 | Robert Granetz | Another fizzle. Adjust dBz/dr up by about 5 mT/m.
Also change magnetics digitisation to 5 kHz. |
| Oct 22 1993 02:04:36:690PM | 931022023 | Robert Granetz | Got it back, disrupted at 0.46 MA. There were a couple of small impurity
injections. No changes for next shot. |
| Oct 22 1993 02:26:12:640PM | 931022024 | Robert Granetz | Fizzle. Null looks awful, due to something funny in the EF1U and/or OH2U
region. Flux loop signals look fine. Why we puzzle over it, we'll take another shot with pre-fill lowered to 1.3e-5 and TF inversion starting at 0.3 s (instead of 0.5 s). We'll need a new background shot for the diamagnetic signals. |
| Oct 22 1993 02:30:21:020PM | 931022024 | Robert Granetz | OH2U current was 1 kA less that on the previous shot just prior to commutation.
|
| Oct 22 1993 02:32:31:890PM | 931022025 | Robert Granetz | No breakdown. For the next shot, raise pre-fill back to 1.4e-5 torr.
|
| Oct 22 1993 02:52:31:430PM | 931022026 | Robert Granetz | Fizzle. OH2's are not getting to the demand current. Steve Fairfax is
going to try the same trick as before, namely, bring OH1 1 kA too high, then ramp it down around -0.1 s in order to help the OH2's reach their demands. This is presumably related to the fact that the TF is in regulation prior to commutation at these lower fields, and this reduces the source voltage available to the Robicon supplies. |
| Oct 22 1993 03:32:26:550PM | 931022027 | Robert Granetz | Fizzle, but looked good
Steve Fairfax is going to raise the alternator voltage from 13,000 to 13,500 volts in order to help the supplies cope with the TF being in regulation. |
| Oct 22 1993 03:34:04:740PM | 931022028 | Robert Granetz | No breakdown. The higher alternator voltage has screwed up the null
again. For the next shot, adjust the field gradient, dBz/dr, and the vertical field, Bz. |
| Oct 22 1993 03:54:52:500PM | 931022029 | Robert Granetz | Dud. Adjust vertical field.
|
| Oct 22 1993 03:55:37:920PM | 931022030 | Robert Granetz | Fizzle. Fields look pretty good. I've decided to abandon operation
at 3.5 T and try instead for 4 T breakdown on the next shot. |
| Oct 22 1993 04:05:17:860PM | 931022031 | Robert Granetz | Got it. Disrupted at 0.44 s. There were a couple of impurity injections
which may have killed the plasma. There were also some non-thermals. The density got kind of low, perhaps because we haven't had a plasma in a while. For the next shot, repeat with no changes. |
| Oct 22 1993 04:22:12:570PM | 931022032 | Robert Granetz | Very similar to the previous shot. Ended by a disruption at 0.46 s.
As with the previous shot, something happened at around 0.4 s, as observed on many of the radiation signals. That is right at the time that a large gain increase happens for Z_XL. For the next shot, get rid of the gain increase in Z_XL. |
| Oct 22 1993 04:38:49:860PM | 931022033 | Robert Granetz | Disrupted at 0.5 s. Ip=-0.68 MA. For the next shot increase gas puffing
after 0.3 s. Also start the TF rampdown at 0.2 s. |
| Oct 22 1993 04:49:41:370PM | 931022034 | Robert Granetz | Disrupted at 0.43 s. Reason: unknown. Try changing R_XL programming, which
was demanding a change of 1 cm at that time. |
| Oct 22 1993 05:02:23:870PM | 931022035 | Robert Granetz | Fizzle. Fields looked pretty good. Just do it again.
|
| Oct 22 1993 05:17:57:400PM | 931022036 | Robert Granetz | Another fizzle. For next shot, delay TF start by 0.4 s, which means that
it won't go into regulation until after breakdown. On this present shot, OH2U had a very large error in its current. |
| Oct 22 1993 05:24:06:220PM | 931022037 | Robert Granetz | Plasma. Disrupted at 0.42 s. Density is quite low. For next shot, increase
gas puff programming. |
| Oct 22 1993 05:43:28:000PM | 931022038 | Robert Granetz | Finally, a reasonable shot. H-mode with ELM's?! Transition occurs at
0.57 s. H-alpha drops until ELMs/L-mode transitions start at 0.605 s. There is a peaking up of impurities, an increase in density, etc, until the spikes start up. The plasma current droops after 0.6 s because we hit a PLC limit on OH1. This caused the ohmic power to drop, and may explain the L-transitions. Next shot, increase PLC limits on OH1. |
| Oct 22 1993 05:57:18:570PM | 931022039 | Robert Granetz | Another H-mode! Occurs at |Btor|=3.2 to 3.1 T. Ip=-0.70 MA. Disrupted
at 0.76 s. Good flattop. Excellent anti-correlation between H-alpha and Prad, density, etc. |
| Oct 22 1993 06:01:13:360PM | 931022040 | Robert Granetz | Alternator failure. No TF or PF supplies.
|
| Oct 22 1993 06:17:26:610PM | 931022041 | Robert Granetz | Another H-mode, but I don't think it's as good. Ended with a disruption
at 0.74 s. Ip=-0.71 MA. Next shot, lower the gas puffing some more. |
| Oct 22 1993 06:24:51:140PM | 931022042 | Robert Granetz | Getting worse. Plasma disrupts at 0.5 s, before it gets into H-mode.
For the next shot, I think I'll go the opposite way with the gas puffing and increase it. |
| Oct 22 1993 06:45:11:170PM | 931022043 | Robert Granetz | Another H-mode, another disruption, this time at 0.58 s. It turns out that
q95 reaches 2.0-2.1 !!. Therefore, for the next shot, ramp the current down as the field ramps down so that q remains at 2.5. |
| Oct 22 1993 06:56:01:580PM | 931022044 | Robert Granetz | Discharge lasted 0.85 s. Marginal H-mode, I think because the ohmic
power is dropping. The next shot will be a dud, so that we can get a background shot for the magnetics, and also for the pressure gauges. |
| Oct 22 1993 07:02:13:630PM | 931022045 | Robert Granetz | Dud (on purpose) for background use by the diamagnetic signals and the
neutral pressure gauge in the divertor. Good dud, all supplies ran. End of run. |
