SL Plan

Start with 1071204023 (1 MA, 5.4 T, 0.8-1.0e20m-2, lower null)

1. run D, E, and J separately for conditioning purposes
initially for short pulses to high power
run longer pulses at lower power
may adjust to press on with conditioning

2. if running well, investigate simultaneous antenna operation

We will modify discharge parameters as deemed necessary.

will be monitoring voltage and power limits
will adjust density and current to avoid J neutral pressure limit

Run Summary

Using a standard 1 MA, we began plasma testing and conditioning of all
transmitters, antennas, and FFT matching network (on E antenna).
Overall the run was quite successful: D conditioned to 2 MW, E
conditioned to 1.75 MW, and J conditioned to 1.5 MW. The addition of
the prematching transformers in the D network reduces the voltage in
the 9" section by ~30% and likely contributed to the high power
obtained today. In addition, the phase shifter and stub tuner have
SF6 in this campaign due to the reduced leak rate. The FFT network
had some problems with its computer and our ability to communicate
with it. For E antenna, DC2 has failed and we think this is due to a
crimped cable. The J antenna improved a bit during the run but
appears to be limited by arcing. Andy measured the water content this
morning and found that it was quite high (~3000 ppm). This is likely
a result of the absorbed water in the teflon. We plan to dry the
lines out by flowing dry nitrogen through the coax lines for several
days and monitoring the water content. We need to increase the pulse
length to 1 second from the current 0.3 second pulse lengths and run
simultaneously (which will have to wait until the H/D gets a bit
lower). With respect to the machine conditions, the density and H/D
increase strongly with RF power and the H/D.

Run summary for Wednesday 05 Dec 2007 MP#355 ICRF startup and conditioning MP#488 Fast ferrite tuner on E-port Session leader: S. Wukitch Physics operator: R. Granetz Plasma operation was very reliable today, particularly since it's only the 3rd or 4th plasma run since closing up the machine. All but one plasma went full-length. The ICRF systems were duly exercised, and all antennas eventually reached power levels of 1.5-1.9 MW for brief periods of time. The FFT on E-port showed promising results on some shots. Late in the run (from shot 19 onwards) the gate valves were kept closed for 300 seconds after each shot so that pressure and RGA data could be taken to study wall retention. There were two long cell accesses to work on RF things and to change the RGA configuration, and this limited the number of shot cycles a bit. Scorecard: 25 plasmas 0 duds 0 fizzles 0 power supply tests 2 no-power MDS shot cycles -------------- Total: 27 shot cycles (The number of shot cycles does not match the the final shot number because one cycle didn't increment the shot counter.)

Physics Operator Comments

Dec 5 2007 08:38:16:413AM Robert Granetz Got the usual ECDC in D2 and the 60 C bake overnight.

Vessel pressure is 3.4e-7 torr at 30 C right now.

Loaded all segments from shot 23 yesterday (1071204023). nl_04 is set to 0.7e20 m-2, but
the shot got to 0.9e20 m-2, so I'll leave it as is for now.

Dec 5 2007 09:13:26:990AM 1071205001 Robert Granetz Shot 01 -- No-power shot. Commutation banks were turned off. MDS cycle ran fine.

Next shot: go for plasma.

Dec 5 2007 09:44:57:890AM 1071205002 Robert Granetz Shot 02 -- Plasma. Good full-length shot. 1 MA, 5.4 T, nl_04=0.76e20 m-2.
Prf[D/E/J]= 0 / 0.2 / 0-0.9 MW. Startup looks quite clean. Wth=50 kJ.
Right gap = 9-10 mm, left gap = 11-12 mm, kappa=1.65.
H/(H+D)=0.15-0.24

Next shot: no DPCS changes

Dec 5 2007 09:48:41:550AM 1071205003 Robert Granetz Shot 03 -- Plasma. Good shot. Prf[D/E/J]= 0 / 0.2 / 0-0.8 MW. H/(H+D)=0.23-0.29

Next shot: turn on argon puff at t=0.30 s for 50 ms.

Dec 5 2007 10:02:38:290AM 1071205004 Robert Granetz Shot 04 -- Plasma. Good shot. Late rampdown was a little dirtier...could that be due
to turning on the argon puffing? Prf from J-port = 1 MW, and much cleaner.
Not much from D+E. H/(H+D)=0.25-0.34

Next shot: no DPCS changes

Dec 5 2007 10:16:17:480AM 1071205005 Robert Granetz Shot 05 -- Plasma. Good shot. Not much from D+E. J didn't work as well as the
previous shot. H/(H+D)=0.28-0.35

Cell access required for RF.

Next shot: increase argon puff to 70 ms (from 50). Add +15 amps to IC_EF4.

Dec 5 2007 11:24:23:587AM 1071205006 Robert Granetz We had an hour-long break between shots 5 and 5 for cell access to work on the FFT and
other ICRF stuff.

Dec 5 2007 11:31:56:463AM 1071205006 Robert Granetz Shot 06 -- Plasma. Good shot. Prf[D+E] still not giving much. J is at 1 MW, with some
faulting. Breakdown is slightly better (finite tangential Z-meter signal), and
the hard x-rays decreased. H/(H+D)=0.30-0.36. The hydrogen fraction has been
rising on a shot-by-shot basis all morning.

Next shot: increase argon puff by another 20 ms (to 90 ms)

Dec 5 2007 11:51:08:550AM 1071205007 Robert Granetz Shot 07 -- Plasma. Good shot. Both D and E had about 0.5 MW...first significant power from
them today. J gets up to 1.2 MW, with some faulting. H/(H+D)=0.30-0.40

Next shot: at Bruce's request, program RXL to move inward by 5 mm over the time from t=1.0 to
1.5 s in order to decrease the vertical sweeping of the outboard strike point.

Dec 5 2007 12:08:26:730PM 1071205008 Robert Granetz Shot 08 -- Plasma. Good shot. D, E, and J all on. D gets up to 0.75 MW, J up
to 1.3 MW. GPC2 has large oscillations on it. H/(H+D)=0.30-0.38

Next shot: increase argon puff another 20 ms (to 110 ms).

Dec 5 2007 12:16:35:170PM 1071205009 Robert Granetz Shot 09 -- Plasma. Good shot. GPC2 still has large oscillations on it. D-port is getting
close to 1 MW. H/(H+D)=0.31-0.39

Next shot: add another 20 ms to the argon puff (to 0.13 s)

Dec 5 2007 12:31:48:847PM 1071205010 Robert Granetz Shot 10 -- Plasma. Good shot. D-port reaches 1 MW; so does J. E had some
faulting problems on this shot. H/(H+D)=0.30-0.42

Next shot: no DPCS changes

Dec 5 2007 12:39:42:477PM 1071205011 Robert Granetz Shot 11 -- Plasma. Good shot. Better performance from D, E, and J.

Next shot: no DPCS changes

Dec 5 2007 01:04:27:657PM 1071205012 Robert Granetz Shot 12 -- Plasma. Good shot. No E-port power, and D-port faulted badly.
J ran without any faults. H/(H+D)=0.31-0.40

Next shot: no DPCS changes

Dec 5 2007 01:10:31:110PM 1071205013 Robert Granetz Shot 13 -- Plasma. Good shot. Disrupted late in rampdown. All antennas going, with
some faulting.

Next shot: increase argon puff another 20 ms (to 0.15 s)

Dec 5 2007 01:26:22:790PM 1071205014 Robert Granetz Shot 14 -- Plasma. Good shot. Disrupted late in rampdown. E ran well; J ran
okay too. We're averaging about 1 MW of ICRF throughout the flattop,
but no heating observed, probably due to high H fraction.
H/(H+D)=0.33-0.42

Next shot: no DPCS changes

Dec 5 2007 01:35:58:573PM 1071205015 Robert Granetz Shot 15 -- Plasma. Good shot. E-port ran well, D and E ran, but with faults.

Next shot: increase argon puff another 20 ms (to 0.17 s).

Dec 5 2007 01:51:16:440PM 1071205016 Robert Granetz Shot 16 -- No-power shot because the cycle got stuck in INIT.

Dec 5 2007 02:11:41:480PM 1071205016 Robert Granetz Shot 16 -- Plasma. Good shot. (This is actually the 2nd shot 16; the first was a no-power
cycle problem.) RF didn't seem to turn on at all.

Next shot: repeat; no DPCS changes

Dec 5 2007 02:24:55:110PM 1071205017 Robert Granetz Shot 17 -- Plasma. Good shot. No RF again.

Next shot: increase argon puff another 20 ms to 0.19 s

Dec 5 2007 03:05:15:123PM 1071205018 Robert Granetz Shot 18 -- Plasma. Good shot. RF turned on for this shot. D-port ramped up
to about 1.3 MW. E-port was close to 1 MW. J-port gets up to 1.7 MW.
H/(H+D)=0.32

Short cell access after this shot to move the RGA to the other side of the bypass
so that we can do some outgassing measurements between shots.

Next shot: Keep the gate valves closed for 300 seconds after the shot. We'll do this
after all shots for the remainder of today's run. On advice of Earl and
Steve Wolfe, I've reduced the pre-fill by 2 ms to compensate for the gate
valve closure.

Dec 5 2007 03:39:59:483PM 1071205019 Robert Granetz Shot 19 -- Plasma. Good shot. Gate valves remained closed for 5 minutes after the shot.
D-port ramped up to 1.5 MW; J-port also peaked around 1.5 MW. Nothing from E-port.
H/(H+D)=0.30-0.40

Next shot: add another 20 ms to the argon puff (to 0.21 s)

Dec 5 2007 03:48:30:710PM 1071205020 Robert Granetz Shot 20 -- Plasma. Good shot. Gate valves are being kept closed for 5 minutes after the
shot. D-port ran well; nothing from E.

Next shot: add another 20 ms to argon puff (to 0.23 s)

Dec 5 2007 04:02:44:733PM 1071205021 Robert Granetz Shot 21 -- Plasma. Good shot. 1-1.8 MW from each of the antennas. No heating though.
H/(H+D)=0.30-0.40

Next shot: increase argon puff by 20 ms again (to 0.25 s)

Dec 5 2007 04:16:27:410PM 1071205022 Robert Granetz Shot 22 -- Plasma. Good shot. 1.5-1.9 MW from each antenna.

Next shot: add another 20 ms to argon puff (to 0.27 s)

Dec 5 2007 04:28:03:417PM 1071205023 Robert Granetz Shot 23 -- Plasma. Disrupted at t=0.3 s, so it wasn't the argon. I'll chalk it up
to a random injection.

Next shot: reduce pre-fill by 2 ms to compensate for the disruption.

Dec 5 2007 04:46:39:670PM 1071205024 Robert Granetz Shot 24 -- Plasma. Good shot. All antennas got up to 1.5-1.9 MW.

Next shot: add 2 ms back to the pre-fill (since this post-disruption shot did not
disrupt)

Dec 5 2007 05:01:09:803PM 1071205025 Robert Granetz Shot 25 -- Plasma. Good shot. Prf=1.5-2 MW from each antenna. H/(H+D)=0.30-0.42

Next shot: reduce pre-fill by 1 ms.

Dec 5 2007 05:05:50:600PM 1071205026 Robert Granetz Shot 26 -- Plasma. Good shot. Prf=1.8-2 MW from each antenna.

Dec 5 2007 09:18:47:943AM	1071205001	Steve Wukitch	no power

E: ran to 0.90 sec. 1 fault - under FFT control J: ran 25 faults notes: J is unlikely to run very well. Our current theory is that the transmission lines still have too high of relative humidity. FFT control is a bit rough D antenna has transformers to reduce voltage in the ps/st set next: repeat with RF run individually

Dec 5 2007 08:38:16:413AM		Robert Granetz	Got the usual ECDC in D2 and the 60 C bake overnight. Vessel pressure is 3.4e-7 torr at 30 C right now. Loaded all segments from shot 23 yesterday (1071204023). nl_04 is set to 0.7e20 m-2, but the shot got to 0.9e20 m-2, so I'll leave it as is for now.
Dec 5 2007 09:13:26:990AM	1071205001	Robert Granetz	Shot 01 -- No-power shot. Commutation banks were turned off. MDS cycle ran fine. Next shot: go for plasma.
Dec 5 2007 09:44:57:890AM	1071205002	Robert Granetz	Shot 02 -- Plasma. Good full-length shot. 1 MA, 5.4 T, nl_04=0.76e20 m-2. Prf[D/E/J]= 0 / 0.2 / 0-0.9 MW. Startup looks quite clean. Wth=50 kJ. Right gap = 9-10 mm, left gap = 11-12 mm, kappa=1.65. H/(H+D)=0.15-0.24 Next shot: no DPCS changes
Dec 5 2007 09:48:41:550AM	1071205003	Robert Granetz	Shot 03 -- Plasma. Good shot. Prf[D/E/J]= 0 / 0.2 / 0-0.8 MW. H/(H+D)=0.23-0.29 Next shot: turn on argon puff at t=0.30 s for 50 ms.
Dec 5 2007 10:02:38:290AM	1071205004	Robert Granetz	Shot 04 -- Plasma. Good shot. Late rampdown was a little dirtier...could that be due to turning on the argon puffing? Prf from J-port = 1 MW, and much cleaner. Not much from D+E. H/(H+D)=0.25-0.34 Next shot: no DPCS changes
Dec 5 2007 10:16:17:480AM	1071205005	Robert Granetz	Shot 05 -- Plasma. Good shot. Not much from D+E. J didn't work as well as the previous shot. H/(H+D)=0.28-0.35 Cell access required for RF. Next shot: increase argon puff to 70 ms (from 50). Add +15 amps to IC_EF4.
Dec 5 2007 11:24:23:587AM	1071205006	Robert Granetz	We had an hour-long break between shots 5 and 5 for cell access to work on the FFT and other ICRF stuff.
Dec 5 2007 11:31:56:463AM	1071205006	Robert Granetz	Shot 06 -- Plasma. Good shot. Prf[D+E] still not giving much. J is at 1 MW, with some faulting. Breakdown is slightly better (finite tangential Z-meter signal), and the hard x-rays decreased. H/(H+D)=0.30-0.36. The hydrogen fraction has been rising on a shot-by-shot basis all morning. Next shot: increase argon puff by another 20 ms (to 90 ms)
Dec 5 2007 11:51:08:550AM	1071205007	Robert Granetz	Shot 07 -- Plasma. Good shot. Both D and E had about 0.5 MW...first significant power from them today. J gets up to 1.2 MW, with some faulting. H/(H+D)=0.30-0.40 Next shot: at Bruce's request, program RXL to move inward by 5 mm over the time from t=1.0 to 1.5 s in order to decrease the vertical sweeping of the outboard strike point.
Dec 5 2007 12:08:26:730PM	1071205008	Robert Granetz	Shot 08 -- Plasma. Good shot. D, E, and J all on. D gets up to 0.75 MW, J up to 1.3 MW. GPC2 has large oscillations on it. H/(H+D)=0.30-0.38 Next shot: increase argon puff another 20 ms (to 110 ms).
Dec 5 2007 12:16:35:170PM	1071205009	Robert Granetz	Shot 09 -- Plasma. Good shot. GPC2 still has large oscillations on it. D-port is getting close to 1 MW. H/(H+D)=0.31-0.39 Next shot: add another 20 ms to the argon puff (to 0.13 s)
Dec 5 2007 12:31:48:847PM	1071205010	Robert Granetz	Shot 10 -- Plasma. Good shot. D-port reaches 1 MW; so does J. E had some faulting problems on this shot. H/(H+D)=0.30-0.42 Next shot: no DPCS changes
Dec 5 2007 12:39:42:477PM	1071205011	Robert Granetz	Shot 11 -- Plasma. Good shot. Better performance from D, E, and J. Next shot: no DPCS changes
Dec 5 2007 01:04:27:657PM	1071205012	Robert Granetz	Shot 12 -- Plasma. Good shot. No E-port power, and D-port faulted badly. J ran without any faults. H/(H+D)=0.31-0.40 Next shot: no DPCS changes
Dec 5 2007 01:10:31:110PM	1071205013	Robert Granetz	Shot 13 -- Plasma. Good shot. Disrupted late in rampdown. All antennas going, with some faulting. Next shot: increase argon puff another 20 ms (to 0.15 s)
Dec 5 2007 01:26:22:790PM	1071205014	Robert Granetz	Shot 14 -- Plasma. Good shot. Disrupted late in rampdown. E ran well; J ran okay too. We're averaging about 1 MW of ICRF throughout the flattop, but no heating observed, probably due to high H fraction. H/(H+D)=0.33-0.42 Next shot: no DPCS changes
Dec 5 2007 01:35:58:573PM	1071205015	Robert Granetz	Shot 15 -- Plasma. Good shot. E-port ran well, D and E ran, but with faults. Next shot: increase argon puff another 20 ms (to 0.17 s).
Dec 5 2007 01:51:16:440PM	1071205016	Robert Granetz	Shot 16 -- No-power shot because the cycle got stuck in INIT.
Dec 5 2007 02:11:41:480PM	1071205016	Robert Granetz	Shot 16 -- Plasma. Good shot. (This is actually the 2nd shot 16; the first was a no-power cycle problem.) RF didn't seem to turn on at all. Next shot: repeat; no DPCS changes
Dec 5 2007 02:24:55:110PM	1071205017	Robert Granetz	Shot 17 -- Plasma. Good shot. No RF again. Next shot: increase argon puff another 20 ms to 0.19 s
Dec 5 2007 03:05:15:123PM	1071205018	Robert Granetz	Shot 18 -- Plasma. Good shot. RF turned on for this shot. D-port ramped up to about 1.3 MW. E-port was close to 1 MW. J-port gets up to 1.7 MW. H/(H+D)=0.32 Short cell access after this shot to move the RGA to the other side of the bypass so that we can do some outgassing measurements between shots. Next shot: Keep the gate valves closed for 300 seconds after the shot. We'll do this after all shots for the remainder of today's run. On advice of Earl and Steve Wolfe, I've reduced the pre-fill by 2 ms to compensate for the gate valve closure.
Dec 5 2007 03:39:59:483PM	1071205019	Robert Granetz	Shot 19 -- Plasma. Good shot. Gate valves remained closed for 5 minutes after the shot. D-port ramped up to 1.5 MW; J-port also peaked around 1.5 MW. Nothing from E-port. H/(H+D)=0.30-0.40 Next shot: add another 20 ms to the argon puff (to 0.21 s)
Dec 5 2007 03:48:30:710PM	1071205020	Robert Granetz	Shot 20 -- Plasma. Good shot. Gate valves are being kept closed for 5 minutes after the shot. D-port ran well; nothing from E. Next shot: add another 20 ms to argon puff (to 0.23 s)
Dec 5 2007 04:02:44:733PM	1071205021	Robert Granetz	Shot 21 -- Plasma. Good shot. 1-1.8 MW from each of the antennas. No heating though. H/(H+D)=0.30-0.40 Next shot: increase argon puff by 20 ms again (to 0.25 s)
Dec 5 2007 04:16:27:410PM	1071205022	Robert Granetz	Shot 22 -- Plasma. Good shot. 1.5-1.9 MW from each antenna. Next shot: add another 20 ms to argon puff (to 0.27 s)
Dec 5 2007 04:28:03:417PM	1071205023	Robert Granetz	Shot 23 -- Plasma. Disrupted at t=0.3 s, so it wasn't the argon. I'll chalk it up to a random injection. Next shot: reduce pre-fill by 2 ms to compensate for the disruption.
Dec 5 2007 04:46:39:670PM	1071205024	Robert Granetz	Shot 24 -- Plasma. Good shot. All antennas got up to 1.5-1.9 MW. Next shot: add 2 ms back to the pre-fill (since this post-disruption shot did not disrupt)
Dec 5 2007 05:01:09:803PM	1071205025	Robert Granetz	Shot 25 -- Plasma. Good shot. Prf=1.5-2 MW from each antenna. H/(H+D)=0.30-0.42 Next shot: reduce pre-fill by 1 ms.
Dec 5 2007 05:05:50:600PM	1071205026	Robert Granetz	Shot 26 -- Plasma. Good shot. Prf=1.8-2 MW from each antenna. End of run
