------------------------------
ECDC Parameters (if requested)
------------------------------
gas and pressure: D2 at 2e-4 Torr
sweep: 44/45/103 cm
scan: 20/120 s
Physics Operator Plan:
-----------------------
Load segs #1 and 2 from 1090911018 and recalculate the magnetics predictors.
If necessary, Load Procedures dpcs_xjump (ASYNC_PROS) and dpcs_piezo_chopper (OUTPUT_PROS) consistent with present operation.
1. Tweak up the startup and
current rise, as indicated in SL_PLAN. Ramp to 1.3MA at 0.5 sec, with
early divert. The main issue in the rampup is to get rid of the limiter contact during the OH1 crossover thrash. Initial target density is 0.75e20
at beginning of flattop (BOF). Rampdown to start at 1.2sec, end at 2.0sec.
ICRF requested at 3MW from 0.5sec to 1.1sec.
2. Do a 3 point density scan (meaning density at BOF): nl04= 0.5, 0.9, 1.3e20;
Keep plasma off the wall during ramp.
3. Use ICRF at 1MW from 0.12 to 0.5sec, then 3MW in flattop. Repeat 3 point
density scan. Continue to keep plasma off the wall.
4. If time of day is getting late, change to a faster rampup, BOF at 0.25sec,
and retune to eliminate crossover thrash. Repeat with and without ICRF in ramp,
possibly with two density targets. This step may be postponed if there seems to be enough time to pick it up later in the day.
5. Using the 0.5sec ramp, use LH in rampup, P_LH>500kW, t=0.15-0.65sec; ICRF at 3MW in flattop. Density scan (at BOF) 0.45, 0.5, 0.55e20. May need to disable
or increase threshold on dpcs_xjump shutdown algorithm for this step (see below). Do we really want to do this? Need to consider possibility of limiter damage.
Steps for increasing threshold on dpcs_xjump to avoid soft abort:
+ Click on the dpcs_xjump button, under DPCS Loadable Procedures, ASYNC_PROS
+ In the Edit Procedure widget, change INPUTS from "NEUTS_HARDS" to "SSD_X02"
( that's a zero between the X and the 2)
+ In the window labeled PARAMETERS, change the value of the THRESHOLD tag
from 1.0e15 to 1.0e16, leave the other tags unchanged.
+ Click the OK button
+ To verify the changes have been entered, click the dpcs_xjump button
on the main PCS screen again, and examine the entries. If they match,
then click Dismiss and proceed.
Note that once the LH section of the run is completed, go back to the
dpcs_xjump Edit Procedure widget, and click the Load Default button at the
top to restore the normal settings, then click OK.
6. If we get this far: Turn off LH, use two step ICRF in rampup, 1MW 0.12-0.25sec, then 2MW from 0.25-0.5sec. Repeat 3 point density scan as in steps 2 and 3.

| Goals for today were to revisit Ip rampup with density variations and various heat sources OH/IC/LH, trying to recover early divert and no to minimal wall contact after diverting
Many discharges were spent trying to recover the good rampup behavior obtained in 1090911 with no wall contacts during rampup, after getting shots 001, 002 and 003 to come up easily. Many, Many, Many 006, this shot had choppy early RF, no inner contact at 120 ms, but kiss outer at 120 ms, an inner kiss at cross-over 007 disrupt at 0.55 s 010 no inner but some outer contact at 120 ms, just a kiss inner at cross-over 012 good ICRF 1-2 MW in rampup, inner and outer touches 015 ohmic, clean discharge, no inner but some outer at 120 ms, kiss inner at cross-over 016 ohmic, beginning to minimize all wall contacts 018 ohmic, again very small contacts 020, ohmic, very small contacts, nl04 = 0.78 at EOR 021 ohmic nl04 = 0.9 022 ohmic nl04 = 1.3 025 ohmic nl04 = 0.5...that is a ninja puff in flattop 026 1 MW IC, nl04 = 0.5 029 1 MW IC, nl04 = 0.9 Seeing no change in OH1 for any variation. Clear contradiction to runday 1090911. Began faster Ip ramp for IO request....basic problem is that early divert requires that we get off the resistors early (40ms) and so we have limited ovltage from power supplies. Maybe other hidden snafus. 400 ms rampup seemed OK, but 250 and 350 ms failed. Overall the run day was very challenging, requiring discharge development since 2009, while trying to do scans. Harder than expected by all. |

| Summary
------- A tough day because of many failed current ramps and disruptions from 1.3MA. Early crowbar and early divert plasmas proved to be prone to current stalls and bounces, in a manner worse than observed on the long prior run 1090911. It did not prove possible to avoid completely the touch of the plasma on the inner wall at OH1 crossover. Early diversion did seem to be possible without instability, and without a limited period (e.g. according to mfil shots 16,18,20,21,22, but many shots had momentary touches, and efit says even those shots just touch). A current ramp to 1.3MA in less than 0.4s is not possible because of OH1 voltage limitations. Physop lessons learned. ----------------------- The low voltage, early crowbar, shot used was originally run without the PG3 -10ms puff that suppresses runaways. It had faster Bz ramps (for no obvious reason), and faster Ip initial derivative. Lowering the PG3 prepuff did not seem to raise the Ip derivative much but did give enough runaways that the shot was terminated under control. Many bounces were experienced. It did not seem to be possible to raise the EF3 voltage at the relevant time (10-20ms) presumably because we are at PS limits. Towards the end of the day bounces seemed to be avoided after a series of lowerings of the OH voltages (which has the effect of raising the Bz ramp rate.) Probably the last shot (33) is a sensible place to start for future development but with more modest Ip ramp after 0.1s. Scorecard ---------

| Aug 1 2012 10:04:01:683AM | 1120801003 | Chuck Kessel | Good recovery on first and subsequent shots...amazing after yesterdays nightmare. ICRF is tuning up with hard matching challenges in rampup. Ian working to remove inner wall contacts in ramp phase. Nice high Te with 2 MW ICRF. Choppy H-modes in flattop as in the previous runday...good enough for rampup studies. |
| Aug 1 2012 10:44:46:460AM | 1120801006 | Chuck Kessel | First inner wall contact at 120 ms eliminated on this shot, cross-over lissing contact still present. No longer forming early x-point at top. |
| Aug 1 2012 12:37:29:493PM | 1120801014 | Chuck Kessel | Working the startup and early equilibrium formation...lots of differences since 2009. Using ohmic discharges to get going. ICRF was making Te(0) up to 5 keV with 2 MW. |
| Aug 1 2012 02:18:23:720PM | 1120801020 | Chuck Kessel | Pretty good ohmic discharge on balance. There are still very short wall contacts, but these may be tolerable since similar OH1 currents are resulting commpared to 1090911 with no contacts. Will begin density scan of ohmic cases next. |
| Aug 1 2012 02:38:35:170PM | 1120801022 | Chuck Kessel | 021 is nl04 = 0.9, and 022 is nl04 = 1.3, ohmic....little difference in OH1 current, but Te appears to drop with n rise. Very short contacts.
Shot 023 is another icky early failure. |
| Aug 1 2012 03:32:01:840PM | 1120801026 | Chuck Kessel | 025 nl04 = 0.5 ohmic, even this case shows no effect on OH1
026 nl04 = 0.5 with 1 MW ICRF, decent rampup, no real effect on OH1, disruption in flattop. ICRF has a jumpy start, but smooth most of the way. 3 MW of ICRF makes the plasma toasty after rampup. |
| Aug 1 2012 04:05:59:957PM | 1120801029 | Chuck Kessel | 029 nl04 = 0.9 with 1 MW ICRF, perfect ICRF in ramp. short contacts. density low early, reflected in higher Te at same time....still not change in OH1.
Moving on to fast Ip ramp. |
| Aug 1 2012 04:34:50:253PM | 1120801031 | Chuck Kessel | tried 250 ms rampup to 1.3 MA, however, the early divertor requirement has us switching from resistors to power supplies at 40 ms, making it impossible for us to get the current to rise due to lower voltage.
try 350 ms rampup |
| Aug 1 2012 04:55:34:330PM | 1120801031 | Chuck Kessel | see wolfe and hutchinson for the detailed discussion of voltage limits and cross-over complex behavior at these faster rampups |
