Engineering setup for Wednesday 21 Nov 2007
MP#298a: Plasma startup
Physics operator: R. Granetz
If the Tuesday evening leak checking is successful, then we should do as
much ECDC in D2 as possible overnight, and bake at 60 C.
Run will start at as soon as the leak checking (if still necessary) is
finished on Wednesday morning, and end at 17:00.
Power systems as on 1071120031
Note: we may want to do between-shot ECDC.
A-coil configuration: +Dtop -Dbot -Jtop +Jbot; Enabled (standard
configuration)
Gas Setup:
fill B-Top with 6 psi D2 Hybrid enabled (PG4)
fill B-side lower with 1 psi Ar Hybrid DISABLED (PG1)
leave B-side upper as is Hybrid DISABLED (PG2)
fill B-main (C-side) with 40 psi D2 Hybrid enabled (PG3)
leave NINJA as is DISABLED
Enable the following gate valves and shutters, assuming no vacuum problems:
ECE
Torvac setup: gate valves open after the shot
Specific diagnostics: plasma TV (wide1, wide2)
-------------------------------------------------------------------------------
ICRF Setup: no
LH Setup: no
DNB: no
Cryopump: no
-------------------------------------------------------------------------------
Run plan: Assuming we find the leak, then begin the run by loading from
shot 1071120031 (all segments). We'll then have several
principal tasks to accomplish:
1) Bang away until we get reproducible breakdown and rampup.
2) Update the DPCS to use the correct estimators for the newly
replaced flux loops (F10, F11, F19).
3) Clean up the machine by running lots of plasmas.
