HT-7 ASIPP Daily Operation Report Operation Team I X. Gong, Z. Zheng, H. Wang, C. Hu, C. Xie, A.Ti 11-12 Dec 2005
Experimental Topic • 1) ICRF experiment for DIA_CO2 • OH discharges for DIA_TS • GAM & Probe Scan • Plasma ramp-up/down +DNB • ICRF Boronization and OH discharges after Bnz • It:2000A-3900A • Vacuum Pressure: 2.0E-5Pa • Wall Temperature: 30C~150C • ICRF: ~250kW LHCD: ~100kW • Shot No.#82617~#8278x
2nd ICRF Boronization • Pre RF+Taylor Discharge Cleaning (1h30mins) • Prf:5~25kw, It:2000A • Last time: 1h30mins • 3g Carborane • Only 30mins low power RF-DC after Bnz • Wall temperature: RT • Without Taylor assistant
High Hydrogen Recycling lead to Uncontrollable Density How to optimize RF-Boronization procedure to be suitable for long pulse discharge?
