A very difficult day. Started off by reloading shot 28 from 1120503. Seg 1 had an RCUR offset of 3000, IC_EF4U at t=0 of 1300 A, and 21 ms of PG4 pre-puff. After many fizzles, we varied these parameters over a large range, and we were able to establish semi-reliable operation with RCUR offset of 7000, 1260 A on IC_EF4U, and 25 ms on PG4. This worked for a few shots then the fizzles started again. We went all the way to 9000 for RCUR offset but this did not help (or change anything at all, really). For the final shot (33) we tried reloading seg 1 directly from 1120503028, but no success.

May 8 2012 08:42:13:857AM	1120508001	Greg Wallace	Changes: Load 1120503028. Remove RCUR jog at 1.2 s. Change Ip in title from 0.55 to 0.8 MA to match programming. Gas valve test shot. Result: PG4 OK, not much of anything from PG3. Next shot: Will try again with stronger demand on PG3.
May 8 2012 08:49:46:070AM	1120508002	Greg Wallace	Changes: Will try again with stronger demand on PG3. Result: Clear rise in pressure from both PG4 and PG3. Next shot: Set PG3 programming back to 80 at 0.0s and 30 at 0.008 s. Try for plasma.
May 8 2012 09:05:11:377AM	1120508003	Greg Wallace	Changes: Set PG3 programming back to 80 at 0.0s and 30 at 0.008 s. Try for plasma. Result: Alternator excitation failed. No power shot. Next shot: Try again for plasma.

Slightly later breakdown, too. Next shot: Add 10 A back to IC_EF4U (-1270 A to -1260 A) to move breakdown earlier.
May 8 2012 04:50:53:943PM	1120508031	Greg Wallace	Changes: Add 10 A back to IC_EF4U (-1270 A to -1260 A) to move breakdown earlier. Result: Fizzle. Bounce again. Breakdown earlier than shot 30. Next shot: Increase RCUR offset to 9000?!?

slow drift phase error 0.2-0.4deg for no plasma shot, which is similar to the noise during calibration shots yesterday.This noise is worse than last run I think. Suspect:Is it from the air mount?

May 8 2012 09:03:24:383AM

lower noise than shot1 for all following frequencies: (1)slow drift <1Hz (2)~5Hz (3)~30Hz
