Physics operator summary for run 990810:

MP 214 -- RF conditioning

SL: Dr. Wukitch, I presume?
PO: R. Granetz

The goal for today:

Continue ICRF development.

Summary: The run was initially delayed, and then finally cancelled, in favor
of giving the RF engineers more time in the power room to get the
power feedback board operational.

Scorecard: 0 plasmas
0 fizzles
0 duds (0 due to lack of one or more power supplies)
2 tests
0 aborted
----------
2 total

Engineering Setup for Tuesday, 990810:

Run will begin at 09:00.
Setup power supplies from shot 990806009 (1 MA, 5.4 T, flattop to 1.4 s)

Two hours of ECDC in D2 prior to run.

Gas setup - fill B-top with 6 psi of D2 Hybrid enabled
fill B-side lower with 1 psi of Ar Hybrid enabled
fill B-side upper with 6 psi of H2 Hybrid DISABLED
fill C-side with 30 psi of D2 Hybrid enabled
leave J-bottom as is Hybrid DISABLED

The following gate valves should be enabled, assuming no vacuum problems:
ECE, VUV

A standard Tuesday morning OH test will be done for shot 1.

-------------------------------------------------------------------------------

Run Plan for 990810: MP 214 -- RF conditioning

Physics operator: R. Granetz

Start by loading 990806009, a 1 MA, 5.4 T discharge. RF may require frequent
access to the power room to debug the new power feedback control circuit(s).

-------------------------------------------------------------------------------

Note: There were two hours of ECDC in D2 prior to this run.

Hybrid coldstart done; initially there was an error message
about an undefined logical name. Executing a $CCL remcam got
rid of this error message on a second invokation.

Load 990806009 (1 MA, 5.4 T, long flattop, nl_04=1.0e20 m-2).

Shot 01 -- Test. This was a no-power shot cycle to check the camac and the
PLC's after yesterday's computer/network problems. All OK.

The start of the run will be delayed until noontime in order to allow the RF
engineers more time in the power room.

Shot 02 -- Test. This was another no-power shot cycle to re-check the camac
and the PLC's after the UPS failure that just occurred.

-------------------
Just before noontime, it was decided to cancel the run, in favor of giving the
RF engineers more time in the power room to get the feedback board up and
running.
