| Run 950126 MP 70. Horne (sl), Wolfe (p0), Silva, Bertolino (eo), Dr. Tinios assisting. The purpose of this run was to investigate our vertical stability by running relativly high elongation and varying hybrid gains. We hoped to experimentally optimize the vertical stability at 600 kA, and then see what sort of useful target plasma we could hold. We ran a variety of gains on slow z, fast z, and wire 10 (extra P and D gain) and on shot 27 settled on P=13, D=12 on fast wires, with slow P at our nominal 1.5. We had several disruptions, but halo currents were not excessive at this current level. After some polishing we raised the current to 800 ka on shot 31, which ran succesfully. Shot 32 had the lower x-point tweaked, and ran at elongation >1.8 for most of the flattop. Shot 33 was a deliberate attempt to cause a high current, high elongation disruption -- to verify that the halo/plasma current ratio, which was not excessive at 600 ka, did not become excessive. The shot did not disrupt, and had elongation about 1.85 for most of the flat-top. The plasmas on shots 32 and 33 fill the vessel to the point where there's not much more one could imagine doing. The effects on stability of raising the plasma current show up very clearly on this run. Higher current improves stability. We could not exceed elongation 1.8 at 600 kA, but were able to at 800 Ka. Statistics -- 33 attempts, 32 good shots. No fizzles. One dud (12) due to a random problem with either the hybrid decoder or jorway. =================== Shot log =========== loaded shot 950106020 with changes.See PO's log. 1 nominal p,d = 13.,16. 2 kept zcur centered for full shot. 200 hz oscillation, +/- 3 v on chopper demand Probably power supply mode. Elong 1.74 for most of the shot, n/ncrit 1.2. 3 Drop zxl a little, gain tweaks on clearin. Ok , 200 hz oscillation +/- 5 v, no saturation on chopper Elongation 1.77-1.78, n/ncrit 1.19 4 Increase clearin 1 cm, I gain from 2 to 4. That did it -- chopper is oscillating severely, disruption at .55 sec. 200 hz oscillation. Chopper is on low rail, but not upper. ELONGATION IS 1.827 AT .5 SEC. n/ncrit = 1.33 Drop P from 13 to (9,16) for next shot. Efit bombed. 5 Disrupted at crossover. Slow z oscillation -- why? Return to clearin to -5 mm (from +5) 6 Same slow Z oscillation Chopper p,d at (9,16.) for next. Shots 4,5,6 had halo I around 90 ka. 7 That worked!. Does this imply that slow Z needs tweaking? elong = 1.78, n/nc = 1.2 8 try (p,d) = (11,16) That worked. 9 try 8 on wire 10 P gain -- (17,16) (p,d) Worked. 200 hz., like 4. elong 1.79, n/nc = 1.15 or so. P2 gain from 1.5 to 3. 10 Worked. 200 hz. drop D gain on wire 10 from 1.0 to .5 -- remember x 10. (p,d) = (10,11) Idea is to test whether mode is plasma or power supply. Disrupted, 150 hz or so. Looks like the plasma mode. 11 try (p,d) 17,18. This should tickle the power supply mode. That worked, 250 hz mode. try (17,20) 12 dud. The hybrid jorway didn't fire. My private cycle ran correctly, so we're assuming it's a random glitch. 13 Good shot. 250 -. 300 hz. Next drop p gain, leave d. Back to (9,20) (p,d) 14 Disrupted., slow oscillation (20 hz.) The oh2's should be able to handle this. 15 disrupted 16 ok 17 17,20 early, 9,20 late. disrupted after gain switch. We need the high p gain, even with high d gain. But we disrupted because we lost slow control, and the chopper current drifted to zero. slow fast D time (10 msec after switch) 3.00000 17.0000 19.9850 0.510000 3.00000 9.00000 19.9850 0.560000 this killed it 18 Go back to 13,20 late (550 msec) That worked. 19 Raise slow Z P gain to 5. at 700 msec, to see if it makes plasma unstable.

| Physics Operator Summary for 950126 (revised) ------------------------------------ MP#070 High Elongation Development SL: Horne PO: Wolfe EO: Silva,Bertolino The primary goal of this run was to systematically map out the PID gain space for a high-elongation equilibrium. Observables included disruptivity and oscillation frequency and possibly growth rate of the vertical mode. The ultimate idea was to identify the optimum gain settings and then raise the elongation, specifically to make a midplane-centered high-elongation plasma to match the antenna and have the x-point in a good position for the divertor. These goals were accomplished, with a little room to spare. The gain space was mapped for a 600kA, kappa=1.75+ equilibrium. The current was then raised to 800ka, and the elongation raised to 1.85, a new C-MOD record and a value exceeding the design spec! I believe this MP can now be declared done. The starting point for this run was 950106020, a 600kA shot in which the ZCUR was ramped from -2cm to the midplane and back down. Segment 2 from this shot was loaded, and the predictors updated. RCUR was loaded from a shot from yesterday (see Problems and Worries, below). Segment 3 (rampdown) was turned off, and the rampdown from 950106020 was used. Shot 1 was essentially a repeat of 950106020. Shot 2 we maintained ZCUR at the midplane for the whole shot, and raised ZXU to 0.03m to avoid going double null; this ran ok, EOUT around 1.75. On shots 3-6 some tweaks were made to the equilibrium, trying to increase elongation and fix some thrashes. A gain scan with fixed equilibrium settings, specifically with CLEARIN at -.005, was done on shots7-27. The principal variations were done on the fast ZCUR gains, on wire 10, which has a souped up derivative gain stage (tau_d = 10msec, as opposed to 1msec on the other wires). In addition, we tried several different values of the P gain on the slow ZCUR (wire 2). Details are in the logbook (topic=PHYSICS OPERATOR) and in Horne's Session Leader summary. We thought that the effective P and D gains were given by Pf=P3+P10 and Df=D3+10*D10, respectively and that Wire 3 gains were fixed at P3=9, and D3=6 for the entire run. However, it turns out (see Problems below) that wire 3 was actually OFF (controller zeroed). Therefore, contrary to the logbook notes and the earlier version of this report, Pf = P10 and Df = 10*D10. Values in this revised report reflect this fact. Three sorts of modes were observed, a fast mode (200-300Hz) associated with the chopper, the plasma mode, and a slow mode which may be associated with OH2 (around 50Hz). Several early disruptions were associated with a mode around 20Hz, which seemed to be partly radial, and appeared to be related to a position thrash before 400msec. This mode required a fairly high P10 gain to overcome, but was not necessarily fundamental. At any rate, most of the gain scan was done with a high Pf gain before .55sec, with variations following this time.The range of fast ZCUR covered was from 0 high-frequency chopper oscillation, but the plasmas ran; Df<2 were unstable. Lots of data on mode frequency and amplitude were obtained, and should be suitable for comparison with Tinios' modeling. The results were qualitatively compatible with his preliminary graphs, based on a lower elongation, to which we referred throughout the gain mapping. An exception was that the effect of slow P gain was different; Gerry predicted higher P2 gain would lead to instability at lower Pf, and the opposite was found, i.e. the low Pf=2 gain case was marginally more stable at P2=8 than P2=1.5. Most of the scan was done with P2=1.5, which has been our nominal setting. Stepping of Pf and Df gains were done to increase the data rate, and showed clear effects on mode frequency and amplitude (see the LOGBOOK). The optimum fast gain was estimated to be around Pf=4, Df=6. Note that these imply a second fast gain wire is NOT necessary. Using this gain setting for the whole shot (except for an early Pf=8), shots 28-30 were equilibrium and programming tweaks to try to increase the elongation at 600kA. These were only marginally successful; some good mode data should be available. Shots 31-33 were at an increased current of 0.8MA. As predicted, these were more stable than the 600kA case. CLEARIN was moved in and the x-point adjusted to improve the strikepoint location. Shots 32 (kappa=1.8) and 33 (kappa =1.85) are good examples. Some strikepoint control would help to restrain the sweep, but these aren't bad as is. We expected 33 to disrupt, and there are some oscillations, but it made it through, so there is a little extra room to push a little more. The disruptions at 600kA were pretty benign. None had halo currents over 100kA. Granetz and Sorci seemed pretty bored. RF was firing at 0.9sec for many shots. Problems and worries: --------------------- Ian's flux predictor algorithm has changed, although the VERSION ID apparently hasn't. Re-calculating the predictors led to a slight change in the maximum factor values. I was concerned that the offset on RCUR might change from its nominal 10000, and didn't feel like fooling with it, so I loaded the RCUR from yesterday's 950125025, which gave a similar waveform. PCS does not flag a change in the CONFIG ID when using IMPORT_SEG. This is a BUG! I had previously noted that a change in BP coil #12 had been made since 1/6, so I knew to recalculate the predictors, but it should have warned me. Shot 13 was a dud due to a Jorway failure on the Hybrid triggers. Only the TF and chopper ran, with small currents on the PF supplies consistent with zero demand. The fizzle detector also did not get its gate, so the TF ran full length. This seems to have been a random event, although long-distance telekinetic interference by Earl Marmar is a possibility. In any case, Earl's record survives. The Argon puff was turned off after shot 6; it probably wasn't a problem, but we wanted to avoid extraneous disruptions if possible. The 2pi bolo signal was noticeably lower than usual for most shots. It was discovered the next day that thefast ZCUR on wire 3 had in fact been turned off by zeroing the controller; this was inherited from the 950106 shot we used to start from. We had believed the gains on this wire were set at P3=9,D3=6, but in fact the effective gains on wire 3 were ZERO. The conclusions and mapping from this run are all still correct and valid, except that the wire 10 gain is in fact the total fast ZCUR gain, since P3 and D3 were effectively zeroed out. Note that the entries in the LOGBOOK under PHYSICS OPERATOR give the wire 10 gains, and so actually give the fast ZCUR gains for each shot. Scorecard: ---------- Plasmas 32 Fizzles 0 Duds 1 (Jorway failure) -------- -- Total shots 33 |

MP#070 HIgh Kappa SL:Horne PO:wolfe EO:Silva Map out the gain space for ZCUR to optimize a high elongation equilibrium. Start by loading SEG2 from 950106020, a shot on which ZCUR was ramped back up to the midplane from -2cm. Recalculate predictors for all magnetics wires (because of change in BP coils BP12 on 1/12/95. Note: PCS does not warn on Import SEG and it should. The RCUR didn't have the 10000 offset in it. ALso, Ian seems to have changed his algorithm; the factor needed to be reduced a bit. Turn off seg 3 rampdown. Load_wire RCUR from SEG2 of 950125025; I don't trust the offset with the new predictor. | |
| Jan 26 1995 08:11:17:720AM | Steve Wolfe | COLDSTART ran ok.
The RCUR programming should be ok, since the two shots have the same outer gap, the left gap in the 950106020 was somewhat larger than yesterday's. Note that Granetz changed the integrator reset on the magnetics to run off a J221, so we need to watch that to be sure it works (we'll know real fast!) Initial wire 10 gains are P=4, D=1 (on 10msec D stage) wire 3 gains are P=9, D=6 | |
| Jan 26 1995 08:41:41:440AM | 950126001 | Steve Wolfe | Shot 950126001:
Setup based on 950106020, except RCUR from yesterday 950125025, as noted in Run notes. Get rid of third Ar puff (at 0.7 sec), leaving 0.3 and 0.5 Segment 3 off (using seg 2 rampdown). No Ar first shot. Shot ran full length. Looks good, no quiver on the chopper. |

Keep ZCUR at midplane all shot. Raise ZXU from 0.02 to 0.03. Runs ok. Maybe a little bit of fuzz on the ZCUR Aout, but not serious. EOUT on shot 1 peaked at 1.77, this one is at 1.74 for whole flattop. |

Leave P2 gain to 1.5 for whole shot, Drop P10 from 8 to 4 at .55 leave D10 at .6 for whole shot Raise elongation by making CLEARIN 0.5 cm more positive. Also start ZXL at its fil=nal value (-1.5 cm) to try to get rid of early EF1 thrash. Disrupted at 1.0 sec. Early thrashing still present? The RF may have done us in on this one. |

Leave P2 gain to 1.5 for whole shot, Drop P10 from 8 to 4 at .4sec leave D10 at .6 for whole shot Redraw CLEARIN and RCUR to deal with early thrash, make CLEARIN more +ve by another 0.5 cm, i.e. to +0.5cm Increase RXU gain to 2.0. Disrupted at 0.65, oscillation starts around .59 |

Leave P2 gain to 1.5 for whole shot, Drop P10 from 8 to 4 at .4sec leave D10 at .6 for whole shot Raise current to 800ka Ran through ok. No sign of a problem. 1.78 elongation |
| Jan 26 1995 04:48:56:280PM | 950126032 | Steve Wolfe | Shot 950126032:
tweak x-point down and in by about .25 cm each, all else same. Made it through ok |
| Jan 26 1995 05:06:23:820PM | 950126033 | Steve Wolfe | Shot 950126033:
INcrease CLEARIN to +0.005 at 0.6sec It ran!, some oscillations around .65 to .75, but it made it through EOUT is 1.85 for the fltattop! A winner! |
