1/2 run day for MP 468:

Basic plan:
Obtain HXR data for LH-modulated plasmas at several conditions (several good shots at each condition):
1) 90 deg ideal phasing, nl04=5e19, Ip=500 kA
2) 90 deg ideal phasing, nl04=7.5e19, Ip=500 kA
3) (time-permitting) 120 ideal phasing, nl04=7.5e19, Ip=800 kA
4) (time-permitting) 120 ideal phasing, nl04=7.5e19, Ip=800 kA
5) (time-permitting and if there is no time for a cell access after #2 is done) 90 deg ideal phasing, nl04=1e20, Ip=800 kA

Plasma starting shot:
1070523021, with Ip changed from 800 kA to 500 kA

LH start settings:
90 deg ideal phasing
Alternating 12.5 ms on, 12.5 ms off from 0.6 to 1.5 s
Net power of ~400 kW desired (see run 1070523, shots 21, 22, 23, and 25 for klystron power settings)

Obtained HXR data for LH-modulated plasmas at 3 conditions (4-5 good shots at each condition):
1) 90 deg ideal phasing, nl04=5e19, Ip=500 kA (Shots 7-11,21)
2) 90 deg ideal phasing, nl04=7.5e19, Ip=500 kA (Shots 13-16, 22)
3) 90 deg ideal phasing, nl04=1e20, Ip=800 kA (Shots 17-20)

Realized that TS was off for shots up to and including 17, so shots 21 and 22 were devoted to recreating conditions 1) and 2) for TS data. Nearly no LH trips, disruption on shot 11.

Run summary for Monday 27 Aug 2007 MP#468 LH-driven fast electron diffusion time measurement (1/2 day) Session leader: A. Schmidt Physics operator: R. Granetz This run involved only one magnetic configuration, at several different densities and two different currents. Most of the shot-to-shot changes involved LH phasing. So it was an easy day for the physics operator (for a change). The machine ran well. The only anomolies were shots 11 and 12, which had early disruptions, with a large shower of glowing debris seen on the WIDE2 and JANT cameras on shot 11. This blew a few fuses in OH1. Fortunately the problem went away on its own. Scorecard: 16 plasmas 1 duds 0 fizzles 0 power supply tests 5 no-power MDS shot cycles -------------- Total: 22 shot cycles

Aug 27 2007 04:19:14:440PM 1070827006 Robert Granetz Shot 06 -- Dud. The indicated Br0 and Bz0 are several mT different than usual, but
we don't believe these MFLUX signals.

density flattop to 1.5 s.

Next shot: add 2 ms to pre-fill.

Aug 27 2007 01:50:15:393PM 1070827009 Robert Granetz Shot 09 -- Plasma. Good shot. Breakdown is now only 1-2 ms late.

Next shot: no DPCS changes.

Aug 27 2007 02:17:51:013PM 1070827010 Robert Granetz Shot 10 -- Plasma. Good shot.

Next shot: no DPCS changes

Aug 27 2007 02:46:42:887PM 1070827011 Robert Granetz Shot 11 -- Plasma. Disrupted at t=0.88 s after first getting resistive. There was a
large spray of glowing particles, most likely from the inboard wall in
the vicinity of K-port. (See JANT and WIDE2 views.)

Next shot: reduce pre-fill by 2 ms (disruption recovery). Raise nl_04 to 0.75e20 m-2

Aug 27 2007 03:08:37:500PM 1070827012 Robert Granetz Shot 12 -- Plasma. Another early disruption. Lots of hard x-rays. Lost some fuses
in OH1.

Power room access required to change fuses and check SCR's

Next shot: no DPCS changes

Aug 27 2007 03:07:05:280PM 1070827013 Robert Granetz Shot 13 -- Plasma. Good shot. Big marfe around t=0.5 s. Got an OH1 coax resistance
warning (pertained to the previous disruption).

Next shot: no DPCS changes

Aug 27 2007 03:25:29:963PM 1070827014 Robert Granetz Shot 14 -- Plasma. Good shot.

Next shot: tweak the density around 0.5 s to get rid of the slight overshoot.

Aug 27 2007 03:36:01:713PM 1070827015 Robert Granetz Shot 15 -- Plasma. Good shot.

Next shot: another tweak to the density around 0.5 s.

Aug 27 2007 03:48:27:913PM 1070827016 Robert Granetz Shot 16 -- Plasma. Good shot.

Next shot: raise nl_04 to 1.0e20 m-2 and Ip to 0.8 MA.

Aug 27 2007 04:07:03:040PM 1070827017 Robert Granetz Shot 17 -- Plasma. Good shot. It turns out that the Thomson diagnostic was mistakenly not turned
on up to now.

Next shot: Turn on Thomson scattering diagnostic. Tweak nl_04 around t=0.5 s.

Aug 27 2007 04:21:40:317PM 1070827018 Robert Granetz Shot 18 -- Plasma. Good shot.

Next shot: no DPCS changes

Aug 27 2007 04:39:26:233PM 1070827019 Robert Granetz Shot 19 -- Plasma. Good shot.

Next shot: tweak nl_04 down to 0.95e20 m-2

Aug 27 2007 04:56:48:807PM 1070827020 Robert Granetz Shot 20 -- Plasma. Good shot.

Next shot: reload seg 2 from shot 10 (0.5 MA, 0.5e20 m-2). Change nl_04 to 0.45e20 m-2 on the
belief that going back down in density will give us an overshoot, and the session
leader wants to match the actual density on shot 10, now that we are getting Thomson
data.

Aug 27 2007 05:24:20:007PM 1070827021 Robert Granetz Shot 21 -- Plasma. Good shot.

Next shot: reload seg 2 from shot 16 (0.5 MA, 0.75e20 m-2). The lithium
pellet injector will be fired at t=1.6 s.

Aug 27 2007 05:29:37:297PM 1070827022 Robert Granetz Shot 22 -- Plasma. Good shot. Lithium pellet injected at t=1.6 s.

End of run.

Aug 27 2007 04:19:14:440PM	1070827006	Robert Granetz	Shot 06 -- Dud. The indicated Br0 and Bz0 are several mT different than usual, but we don't believe these MFLUX signals. Next shot: increase pre-fill 3 ms.
Aug 27 2007 01:19:57:410PM	1070827007	Robert Granetz	Shot 07 -- Plasma. Good shot. 0.5 MA, 5.4 T, 0.5e20 m-2. P_LH=0.4 MW (modulated). Next shot: extend Bt flattop out to 2.1 s. Decrease pre-fill by 1 ms. Also extend density flattop to 1.5 s.
Aug 27 2007 01:31:47:570PM	1070827008	Robert Granetz	Shot 08 -- Plasma. Good shot. Breakdown is still late. Some early hard x-rays. Next shot: add 2 ms to pre-fill.
Aug 27 2007 01:50:15:393PM	1070827009	Robert Granetz	Shot 09 -- Plasma. Good shot. Breakdown is now only 1-2 ms late. Next shot: no DPCS changes.
Aug 27 2007 02:17:51:013PM	1070827010	Robert Granetz	Shot 10 -- Plasma. Good shot. Next shot: no DPCS changes
Aug 27 2007 02:46:42:887PM	1070827011	Robert Granetz	Shot 11 -- Plasma. Disrupted at t=0.88 s after first getting resistive. There was a large spray of glowing particles, most likely from the inboard wall in the vicinity of K-port. (See JANT and WIDE2 views.) Next shot: reduce pre-fill by 2 ms (disruption recovery). Raise nl_04 to 0.75e20 m-2
Aug 27 2007 03:08:37:500PM	1070827012	Robert Granetz	Shot 12 -- Plasma. Another early disruption. Lots of hard x-rays. Lost some fuses in OH1. Power room access required to change fuses and check SCR's Next shot: no DPCS changes
Aug 27 2007 03:07:05:280PM	1070827013	Robert Granetz	Shot 13 -- Plasma. Good shot. Big marfe around t=0.5 s. Got an OH1 coax resistance warning (pertained to the previous disruption). Next shot: no DPCS changes
Aug 27 2007 03:25:29:963PM	1070827014	Robert Granetz	Shot 14 -- Plasma. Good shot. Next shot: tweak the density around 0.5 s to get rid of the slight overshoot.
Aug 27 2007 03:36:01:713PM	1070827015	Robert Granetz	Shot 15 -- Plasma. Good shot. Next shot: another tweak to the density around 0.5 s.
Aug 27 2007 03:48:27:913PM	1070827016	Robert Granetz	Shot 16 -- Plasma. Good shot. Next shot: raise nl_04 to 1.0e20 m-2 and Ip to 0.8 MA.
Aug 27 2007 04:07:03:040PM	1070827017	Robert Granetz	Shot 17 -- Plasma. Good shot. It turns out that the Thomson diagnostic was mistakenly not turned on up to now. Next shot: Turn on Thomson scattering diagnostic. Tweak nl_04 around t=0.5 s.
Aug 27 2007 04:21:40:317PM	1070827018	Robert Granetz	Shot 18 -- Plasma. Good shot. Next shot: no DPCS changes
Aug 27 2007 04:39:26:233PM	1070827019	Robert Granetz	Shot 19 -- Plasma. Good shot. Next shot: tweak nl_04 down to 0.95e20 m-2
Aug 27 2007 04:56:48:807PM	1070827020	Robert Granetz	Shot 20 -- Plasma. Good shot. Next shot: reload seg 2 from shot 10 (0.5 MA, 0.5e20 m-2). Change nl_04 to 0.45e20 m-2 on the belief that going back down in density will give us an overshoot, and the session leader wants to match the actual density on shot 10, now that we are getting Thomson data.
Aug 27 2007 05:24:20:007PM	1070827021	Robert Granetz	Shot 21 -- Plasma. Good shot. Next shot: reload seg 2 from shot 16 (0.5 MA, 0.75e20 m-2). The lithium pellet injector will be fired at t=1.6 s.
Aug 27 2007 05:29:37:297PM	1070827022	Robert Granetz	Shot 22 -- Plasma. Good shot. Lithium pellet injected at t=1.6 s. End of run.
