Apr 20 2004 01:16:02:153PM1040420001Steve WolfeTest of Bside-Upper (pg2)
Shot#1: set up 10msec wide puff in segment 1 to test how much gas comes in
Got about .0007 mtorr, according to the raiomatic. Don't know what that means
in real units, since it's Helium.

next shot: 20msec
Apr 20 2004 01:20:53:573PM1040420001Steve WolfeTest of Bside-Upper (pg2)
Shot#2: set up a 20msec puff for comparison
Delay because daq system failed on shot 1

Apr 20 2004 01:31:50:360PM1040420001Steve WolfeShot#2 : No Tom or Josh. Gary tried restarting cycle,
but init didn't complete
Forced it through anyway, but it seems not to have done anything.
Apr 20 2004 03:19:19:297PM1040420005Steve Wolfeshot 5: Tom and Josh finally got a cycle to work (sort of)
20msec pulse gives ratiomatic signal of .005mTorr
Apr 20 2004 03:30:06:657PM1040420006Steve Wolfeshot 6: Try a 15msec pulse, if they get it ready to go again.
got 4.2 uTorr, not much diffferent from shot 5 with 20msec

next shot: try 10msec again.
Apr 20 2004 03:43:47:360PM1040420007Steve Wolfeshot 7: try 10msec again. Nothing visible on ratiomatic.
No pulse on high voltage amp. There is a pulse on mout 16.

next shot: try again
Apr 20 2004 03:47:28:547PM1040420007Steve Wolfeshot 8: OK, that time we got it? Don't know why 7 failed.
This time it got .002mTorr on ratiomatic.

next shot: 30msec
Apr 20 2004 04:00:15:313PM1040420007Steve Wolfeshot 9: 30msec pg2 puff
camac failed on ratiomatic signal
dispatched the store manually

.014mTorr
