Plan for A-coil tests on Monday, Mar 3, 2008

We require two pulses with just the A-coils (TMX supply)
after the cell is secured for boronization on Monday afternoon. 

Engineering setup as on 1071120008: basically enable the A-coil
for Hybrid control, and move the fizzle detector times to [1.7,1.8]
With C-coil start time = -0.2, stop time=2.0, volt=300, cur=1kA

For the first shot: run PCS programming exactly as on 1071120008
For the second shot: Raise the C-coil PLC limit to 600V, 3kA
and program 4000A pulse in PCS.

Load from 1071120008.
Verify that it has the acoil waveform in seg1, segs 2-4 off
Change title of seg1 to "Acoil test"
Zero_all on wires 1-7, just for fun so I don't use the old magnetics
for anything
Do a build_all to test; no errors
Load at  3-Mar-2008 13:53:32.00

Shot#1: Acoil test, should look like 1071120008
Had to wait until EFCU got to -25C because the TMX's are all 
tied to the I2t chain, even though there is no I2t or cooling
on the A-coils. 

Looks similar, maybe some signals a little lower. Go on with the full current
pulse

BP values line up quite well from bpsig_ccoil.pro, 
very similar to 1071120008. I think the coils are ok.

Shot#2: Acoil test, 4000A program
I2t fault in INIT. Have to re-do it.

Shot#3: Acoil test, 4000A program
Got it, data look good, I'll do the detailed comparison after 
staff meeting

Shot#3: Acoil test, 4000A program

The Bp data on this shot look spot on with the prediction of 
bpsig_ccoil.pro, eliminating known bad loops.

Conclusion: The D and J A-coils are still working correctly.
