We will be running a few tests with the Bbot A-coil,
in preparation for runs on Friday (and perhaps Wednesday).

Drawn waveform for the A-coil begins at .2sec, flat at 2000A
until 1.5sec.

Requested tap configuration: [-Bbot -Dtop +Gbot +Jtop]
Fizzle detector to 1.7sec.

Shot#1: Requested tap configuration: [-Bbot -Dtop +Gbot +Jtop]
I almost got that wrong again! 
Draw waveform=2000A, expect ~1500A
No power test - I2t fault

Shot#2: Requested tap configuration: [-Bbot -Dtop +Gbot +Jtop]
Draw waveform=2000A, expect ~1500A
No faults, bp signals present, difs ~5mT
Got 2300A. 
Next shot:Try drawing 3500A

Shot#3:drawing 3500A
Andy is watching some heaters which are right next to
the Bbot coil. 
No faults - Got same current as before.
I was drawing in segment 2 and segment 4 was on:
Actual drawn waveform was 2500A, which makes more sense
next shot: draw 4000A

Apr 11 2005 08:10:17:390AM1050411004Steve Wolfe
Shot#4: draw 4000A. Really using seg2 this time.
No faults, Andy reports some movement.
Signals on magnetics are bigger, as expected.
Got 3600A. 

Testing completed. We will need to secure the heaters
located near the coil; Andy says they slid across the deck
and slapped into the coilcase.
