| Nov 14 2000 09:28:27:230AM | 1001114001 | Brian Labombard | Shot 1 - 1.0 MA, NL04 ~ 1.0, Bt = 5.3 ASP setup for today: N-S in Vf mode, E-W in single probe sweep mode Reduced bias voltage on East probe (still has a shorting problem) FSP setup for today: N-S in Vf mode, E-W in SINGLE probe sweep mode (double sweep power supply is dead) ASP and FSP scanning at 0.7, 0.95, and 1.2 seconds in far sol C2D4 plumes. Next Shot: dial up 0.8 MA, NL04=0.6 and ramp Bt down to 4 tesla for time period 0.7 to 1.2 seconds |

| Nov 14 2000 08:52:07:843AM | Bill Rowan | Engineering Setup for Tuesday, November 14 MP#267 - NL scan with reversed Bt and Ip SL: LaBombard PO: Rowan Engineering setup: ------------------- Overnight ECDC in D2, stopping 1-2 hours before run. Run begins 9:00 and ends at 17:00 Power System Setup: Same as on 1001109022 Gas setup - fill B-top with 6 psi of D2 Hybrid enabled fill B-side lower with 1 psi of Ar Hybrid DISABLED fill B-side upper with 35 psi of D2 Hybrid DISABLED, for ECDC fill C-side with 30 psi of D2 Hybrid enabled leave J-bottom as is Hybrid DISABLED The following gate valves should be enabled, assuming no vacuum problems: ECE, VUV, DNB, Beast The following transmitters should be turned on 1, 2, and 4 Run Plan (LaBombard) ------------------- Start with shot#1001109022 which was a recent 1.0 MA, 5.3 tesla, NL04 = 1.2 discharge (reversed Ip and Bt) with good probe targeting, gaps etc. Then change plasma current to 0.8 MA, Bt to 4 tesla, and NL04 = 0.6x10^20 m^-2. Shot#1-3 NL04 = 0.6x10^20 m^-2 Ip = 0.8 MA, Bt = 4 tesla Setup equilibrium and FSP/ASP target. Take two shots at each condition to optimize scanning probe insertion depths. 4,5 - NL04 = 0.6, Ip = 0.8, Bt = 4 6,7 - NL04 = 0.9, Ip = 0.8, Bt = 4 8,9 - NL04 = 1.2, Ip = 0.8, Bt = 4 10,11 - NL04 = 1.2, Ip = 0.8, Bt = 6 12,13 - NL04 = 0.9, Ip = 0.8, Bt = 6 14,15 - NL04 = 0.6, Ip = 0.8, Bt = 6 16,17 - NL04 = 0.5, Ip = 0.53, Bt = 5.3 18,19 - NL04 = 0.7, Ip = 0.53, Bt = 5.3 20,21 - NL04 = 0.9, Ip = 0.53, Bt = 5.3 22,23 - NL04 = 1.0, Ip = 1.06, Bt = 5.3 24,25 - NL04 = 1.3, Ip = 1.06, Bt = 5.3 26,27 - NL04 = 0.7, Ip = 1.06, Bt = 5.3 As requested, ECDC ran all night and was turned off at about 7am. Loaded PCS from shot 1001109022 Did Load/Clean. Did cold start and completed at 14-NOV-2000 08:30:29.84 Start with a lower density. Reduced NL_04 to 1e+20 Did Load/Clean | |
| Nov 14 2000 09:01:51:560AM | Bill Rowan | Late start. Waiting for alternator. Expect first shot at approx 9:15 | |
| Nov 14 2000 09:26:47:920AM | 1001114001 | Bill Rowan | 001. Plasma Next shot. Reduced TF current from 150000 to 112000 to reduce BT to 4 T Reduced IP from 1MA to 0.8 MA Reduced NL_04 from 1e20 to 0.8e20 |
| Nov 14 2000 09:40:23:687AM | 1001114001 | Bill Rowan | Computer problems while in init for 002. Josh resolving. |
| Nov 14 2000 10:08:04:170AM | 1001114003 | Bill Rowan | 003. Fizzle Next shot. Increased prefill by 2 ms Reduced BR by 0.5 mTs |
