| Engineering setup for Tueday November 12th, Run 1021112 Faraday Rotation Experiments Session leader: Tejero Physics Operator: Irby ECDC until Tuesday morning in D2 stopping by 07:00. Run will begin at 10:00 and end at 17:00 Engineering setup as on 1021105007 Power systems the same as shot 1020822010 Gas setup: fill B-Top with 6 psi D2 Hybrid enabled (PG4) fill B-side lower with 1 psi Ar Hybrid enabled (PG1) fill B-side upper with 10 psi D2 Hybrid DISABLED (PG2) (for ECDC) fill C-side with 30 psi D2 Hybrid enabled (PG3) J-Bottom should be disabled and pumped out Enable the following gate valves: ECE, VUV, DNB ------------------------------------------------------------------------------- RF Setup: No Rf required ------------------------------------------------------------------------------- Standard 800 kA plasma will be produced and the noise level of the Faraday Rotation prototype diagnostic will be determined. Cell entry may be required often during the day as we make adjustments to the diagnostic alignment. TCI will be disabled during this run. |

| Nov 12 2002 08:34:07:070AM | 1021112001 | Jim Irby | Loaded shot 1021105007 into seg 2 --- 5.4T, 800 kA, 8e19/m^2 Dropped Tf to 150 kA in seg 1 This was a test shot ----- check data system and prepuff Pressure for 1021108023 0.545 at t=0 Pressure for 1021112001 0.583 at t=0 |
| Nov 12 2002 10:06:40:337AM | 1021112002 | Jim Irby | This shot will be another test shot with the fizzle detector ON time moved to 1.0 s ---- see that the gas puff is working properly ---- permanent record of baseline for Faraday signal Reduced prefill from 28 to 27 ms Dropped NL04 gain to 0 and made request negative Pulse_gas3 has been programmed full on from 100 to 150 ms then ramped down to 60volts at 400 ms Faraday and pressure data look good |
| Nov 12 2002 10:31:55:907AM | 1021112003 | Jim Irby | Nice plasma Good Faraday signal ---- less than 100 counts Too much prefill |
| Nov 12 2002 10:46:07:773AM | 1021112004 | Jim Irby | Prefill from 27 to 26 ms Increased Ip request to 850 from 800 kA --- see effect on Faraday signal Fizzle --- pressure actually went up ... Nice no-plasma baseline for Faraday |
| Nov 12 2002 10:56:29:540AM | 1021112005 | Jim Irby | Repeat Nice plasma into rampdown --- got more Ip Faraday signal looks good |
| Nov 12 2002 11:13:12:220AM | 1021112006 | Jim Irby | Ip request to 900 kA Fizzle again: too much prefill Faraday signal still okay |
| Nov 12 2002 11:28:16:400AM | 1021112007 | Jim Irby | Gas from 26 to 24 ms Plasma into rampdown --- got Ip request Good Faraday signal |
| Nov 12 2002 11:52:15:797AM | 1021112008 | Jim Irby | Will increase gas puff for higher density this shot ---- puff now at 100% until 400 ms Prefill from 24 to 23 ms Fizzle ---- fields okay, still gas? Faraday signal good --- may see effect of OH1 |
| Nov 12 2002 12:55:06:440PM | 1021112009 | Jim Irby | Erik went into cell before this shot to check Faraday signal out --- signals looked good --- slight tweaks made Prefill from 23 to 22 ms No plasma Run cancelled to check out TF fuses |
