| Run plan and engineering setup for Tuesday, 990420 Engineering Setup for Tuesday, 990416 Load from 990416006 The run will not start until 9:00 am, in order to allow 1 hour of ICRF antenna conditioning prior to start of plasma operation. 2 hours of ECDC in D2, stopping in time to begin antenna conditioning at 08:00. Gas setup - fill B-top with 6 psi of D2 Hybrid enabled fill B-side lower with 1 psi of Ar Hybrid enabled fill B-side upper with 6 psi of H2 Hybrid DISABLED fill C-side with 30 psi of D2 Hybrid enabled leave J-bottom as is Hybrid DISABLED Replace the ethylene bottle with hydrogen.

| Physop run summary 990420 MP 214 -- ICRF conditioning SL: Wukitch PO: Marmar EO: Silva/DeKow Load from 990416006 2 hours of ECDC in D2, stopping in time to begin antenna conditioning at 08:00. Gas setup - fill B-top with 6 psi of D2 Hybrid enabled fill B-side lower with 1 psi of Ar Hybrid enabled fill B-side upper with 6 psi of H2 Hybrid DISABLED fill C-side with 30 psi of D2 Hybrid enabled leave J-bottom as is Hybrid DISABLED Replace the ethylene bottle with hydrogen. The run started late, but after we got going, the machine ran well. We had 17 good plasmas in a row. The only PCS changes involved minor density tweaks. Shot 21 was programmed to run the main segment 2 gas puff through PG5, J-Bottom. The shot fizzled, because of a trip of the EF3 power supply. However, the gas programming did as was expected, switching from C-side to J-bottom at 0.1 seconds. This was the last attempt of the day, as fuses were blown on the EF3 supply. Shot 19 had a flux loop problem \mag_flux_full.signals:f03 has a baseline offset -1.3E-01 and this apparently caused the plasma to move, at least according to Brian, who complained that his probe saw greatly increased heat flux. Also, efit did not work properly for this shot, with mostly unconverged equilibria. The loop was ok on the subsequent shots. The RF made some progress today, with both D and E port running together on some shots. Maximum power was on shot 10, with about 2.7 MW. For details, see the session leader's run summary and entries in the logbook. Score Card: 3 tests 17 plasmas 1 power supply fizzle 21 cycles |
