Physics Operator Plan for Tuesday, May 15, 2007

MP#488 Evaluation of the Fast Ferrite Tuning System
MP#355 ICRF Testing and Conditioning


SL: S. Wukitch and Y. Lin
PO: Rowan

Engineering Setup
------------------

The machine will be boronized on Monday, May 14.

NO post-boronization ECDC -- NONE overnight, NONE in the morning.

Run begins at 10:00 and ends at 17:00

Power systems as on 1070510007
Acoil: +Dtop -Dbot -Jtop +Jbot (standard) Hybrid Enabled

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)
pump out NINJA and backfill with 8 PSI of D2, then disable.

Enable the following gate valves and shutters, assuming no vacuum problems:
ECE, VUV, Z-bolo shutters; Enable DNB gatevalve if requested by DNB operator.

Torvac setup: Pumpstack gatevalves OPEN
RGA's valved off (isolated from machine)

ICRF: FMIT#1,2 in RUN-ON by 08:30
ICRF: FMIT#3,4 in RUN-ON by 06:45

LH: None

Start with PCS loaded from 1070510007. This shot is selected because it is the first
shot from 1070510 with removal of seg2 Pg3 puff at 0.7sec. The puff resulted in
high neutral pressure which was the cause of difficulties with J-port ICRF operation.)

The ICRF conditioned without plasma today. At 2pm, it was clear that this would not be finished by the end of the day so C-Mod was shut down and ICRF conditioning continued.

The start of the run will be delayed past 10am due to ICRF conditioning. Stay tuned!
