| MP700 Edge CXRS Dalpha Diagnotic Cross-Calibration
The primary purpose of these experiements is to cross-calibrate the low field side (LFS) and highfield side (HFS) photodiode systems used to measure Dalpha for the edge CXRS system. For this purpose, they are both setup to measure Dalpha emission on the HFS periscope. In a first step, establish L-mode plasmas. Adjust the left gap for optimal coverage of the Dalpha views. A number of cell accesses will be required in the following to setup different connections of the two photodiode systems. ICRF and possibly LH will be piggy-backing for conditioning. |

| The run went relatively well today although the fizzle rate was
somewhat high. Also I battled early runaways much of the day. In addition a computer hang-up involving a loss of access to model trees occurred around 10:30, resulting in some no-power tests and a half-hour delay in progress. After a good gas test and a successful reload of 1120503001, the next 5 plasma attempts were all fizzles, suggesting no improvement at all from yesterday's struggles. The tendency to fizzle was not helped by tweaks to EF4U and fill gas. Finally, Steve Wolfe recommended significant changes to the programed EF3 and OH1 voltages before and around 0.02s, in order to accelerate field penetration. This actually worked, and led to a sequence of non-fizzles (shots 010--020). Early runaways were a problem on some of these discharges. Tweaks to the pre-fill and to the PG3 puff at t=0 were ineffective in moderating this. However, moving the start of the PG3 maintenance puff earlier did seem to have a positive effect. I did this beginning with shot 018. After this there were mostly good startups, with a few fizzles thrown in. SLs had several cell accesses to modify their fiber arrangement and allow cross calibration of their CXRS channels. In the latter part of the run we obtained density scans and an inner gap scan for further CXRS shakedown. We attempted a locked mode calibration for the HIREXSR on shot 027, but this was one of our fizzles. Tally: 19 plasmas into rampdown 1 early disruption 10 fizzles 3 no power tests

First PCS froze and had to be blown away because (?) access to the model trees was lost. Josh reparied the obvious problems and we attempted a no-power shot following shot 6. NPT not successful. Shot number didn't advance. |

More significant changes now. Dr. Wolfe is on call. In seg 1 raise EF3_VOLT to 3000 at 0.02 and 0.026s. Then in seg 1 lower OH1_VOLT control points from 0 to 0.02s by about 50V. This should improve the field penetration during early ramp-up.

SLs are rearranging fibers again in the cell. There is talk of loading a locked mode shot (1120502009). The active segment in that shot was 4.

Changes: Want to reload a shot SL liked, then reduce inner gap. Load from 1120509026. In Seg 2, reduce CLEARIN from -0.001 to -0.004 In Seg 2, reduce RCUR from 0.6590 to 0.6575 Load at 9-May-2012 16:27:23.00 Open tree /home/jwhughes/physop/pcs_scratch -1 Open tree done Didn't change anything in Seg 1, but if it fizzles again, I'll have to try something. Result: Plasma, full length. Looks like we got a ~8mm inner gap and a ~1.2cm outer gap, compared with ~1cm each on 026. |
| May 9 2012 04:53:42:767PM | 1120509032 | Jerry Hughes | Shot 32
