| Physics operator summary for run 971103 MP 170A, Re-start C-Mod and begin 80 MHz RF conditioning SL: Hutch PO: Granetz EO: Silva Summary: The run was cancelled around 11:00 due to an overtemp indication on an alternator bearing. After the alternator came to a stop, it was determined that the instrumentation was working properly, so one side of the bearing did indeed reach 180 F. Scorecard: 0 plasmas 0 fizzles 0 duds 0 tests ---------- 0 total ------------------------------------------------------------------------------ Run Plan for Monday, 971103 MP 170A -- Restart plasma operation, and begin conditioning 80 MHz ICRF Engineering setup for Monday, 03 Nov 1997: Overnight ECDC in deuterium, if anyone is around on Sunday. Engineering setup as on 971030015, with TF under hybrid control Plasma current to be set for 0.8 MA Segment 1 startup will be copied from 971030015 Density to be set for nl_04=1.0e20 m-2, if TCI is available, else use the pre-programmed gas valve trace from the setup shot. Gas setup - fill K-side with 20 PSI of D2, hybrid enable fill B-top with 6 PSI of D2, hybrid enable fill B-side-lower with 4 PSI of Ar, hybrid enable The following gate valves should be enabled, assuming no vacuum problems: None (until we verify the status of each system) ------------------------------------------------------------------------------- Detailed shot log: Note: the machine was boronized at the end of last week. Note: no ECDC was done prior to this run. Hybrid coldstart done; no errors found ($set default cmod$models:[hybrid.tcl] $@hybinit_dispatch $@show_bitbus_log Use editor to search for no "error" and no "not respond") Reload plasma shot from last Thursday (971030015), which has Ip=0.8 MA and Bt=5.3 T. Turn nl_04 feedback back on. Gain is set at 4, starting at 0.082 s. Start of run will be delayed until 10:30-11:00 to allow alternator to warm up. Run cancelled due to an overtemp indication on an alternator bearing. |
