| Run summary for 990924, MP218, Impurity Transport Coefficient Profiles in EDA H-mode The purpose of this run was to determine the profiles of the impurity diffusion coefficient and convection velocity during EDA H-mode. There was one excellent discharge for study, 990924005, and then the run was cancelled due to a warm reading on one of the TF windings. |

| Physics operator summary for 990924 EO: Silva PO: Goetz SL: Rice Run 990924 was in support of MP 218 -- Impurity Transport Coefficient Profiles in EDA H-Mode. Run repetitive shots similar to Shot 990920015 and inject CalciumFluoride and scan HIREX and MCP spectrometers to measure Ca and F charge states and their distribution. Nothing was done today toward completion of the MP. Three shots were taken with the last having 2.8MW of RF for a nice EDA plasma with CaF injection. All three had good breakdowns and current rises. The run ended early due to concerns over an above normal temperature reading in the TF magnet. Engineering, computing, and diagnostics today: A critical CAMAC initialization error led to a dud for shot 2. There were indications of above normal temperatures in the TF magnet and the run was stopped early to investigate these measurements. Scorecard: 11 shots = 3 plasmas + 0 fizzles + 1 duds + 7 tests Shot summary for Run 990924: Load 990920015 reduce BR_0 from .0005 -> 0.0 Change nl_04 from 0.9e20 -> 1.0e20 extend TF flattop from 1.4 -> 1.5sec and move wiggle to 0.9->1.1s coldstart hybrid - everything loaded; all matrices respond Shot change result ____ _____ ______ 1 test shot of CAMAC 2 dud no EF1s or OH1; had an INIT->RECOOL transition because of critical CAMAC initialization error 3 see above plasma; b.d. @ .006; good current rise 4 draw (100V x 100ms) @ 0.3s on plasma; b.d. @ .006; good current rise PG2 CaF injection into EDA H-mode 5 make PG2 200ms plasma; good current rise; 2.8MW EDA strikes on the floor 6 no power cycle for TF scanner 7 no power cycle for TF scanner 8 no power cycle for TF scanner 9 no power cycle for TF scanner 10 no power cycle for TF scanner 11 no power cycle for TF scanner |
