SL Plan:

Goal:

Investigate antenna pressure limit and investigate range of operation for
given neutral pressure.

Plan:

Use near "standard" LSN (1070608017)

1. scan plasma density -> establish density range
start at nl_04~0.7->1.4 or neutral limit
2. scan plasma current - does it effect neutral limit
3. neutral pressure limits with He plasmas (will need to pump out B-main and fill with 32 psi of 4He)
4. if time available, neutral pressure limits with plasma shape

Run summary

The run was limited by a fizzle problem that persisted all day but we did complete a current scan from 0.6 -> 1 MA at 5.4 T. We were unable to reproduce the neutral pressure limit current dependence observed during operations in other experiments. In the past we have seen large variations (0.1 - 0.6 mTorr) on the neutral pressure limit with plasma current but during this run the limit was fairly constant at about 0.6 mTorr with max at ~0.65 mTorr for 1 MA and 0.6 mTorr for 0.6 MA.

It was a very tough day for the physop. The startup was very difficult to reproduce. Small changes to prepuff,
EF4 current, and even Br0 were made throughout the day to attempt to tune up the startup to no avail. Some
shots went fine and the startup looked great, but the next shot almost always fizzled sometimes with several
fizzles in a row and never with more than two plasmas in a row. Shot 6 also failed because the TF failed for
unknown reasons. The shot summary is below with a total of 13 plasmas, 19 fizzles, and 1 power supply fault.

Physics Operator Comments

Jun 20 2007 09:07:12:703AM 1070620001 Joseph Snipes Shot 1: Copied shot 1070608017 and set prepuff to 20 ms duration in segment 1. Good shot with a number of
faults on D and E port antennas.

Jun 20 2007 09:20:50:660AM 1070620002 Joseph Snipes Shot 2: Increased nl04 to 1.1 x 10^20 m^-2. Set prepuff back to 18 ms duration. Fizzle!

Jun 20 2007 10:01:46:687AM 1070620005 Joseph Snipes Shot 5: Increased nl04 to 1.4 x 10^20 m^-2. Fizzle! CII levels rather high
after the disruption in rampdown due to high density not pumping out as the
current comes down.

Jun 20 2007 10:11:52:990AM 1070620006 Joseph Snipes Shot 6: Reduced RCUR and CLEARIN at a faster rate during rampdown to shrink the plasma faster
as the current ramps down. No TF.

Jun 20 2007 10:27:11:020AM 1070620007 Joseph Snipes Shot 7: Try again with TF and plasma current. Fizzle! High CII again.

arcs and sparks on the video.

Jun 20 2007 11:43:08:593AM 1070620013 Joseph Snipes Shot 13: Try again to get H-mode with more RF power. Fizzle!

Jun 20 2007 11:57:39:213AM 1070620014 Joseph Snipes Shot 14: Repeat with no changes. Fizzle!

Jun 20 2007 01:17:22:413PM 1070620017 Joseph Snipes Shot 17: Increased prepuff by 3 ms to 23 ms duration. One more once. . . Good shot. Disrupted in rampdown at
1.76 s. A-coils were apparently left enabled. We are going to punt this attempt to check locked modes and
move on to the ICRF conditioning run.

Jun 20 2007 01:26:30:750PM 1070620018 Joseph Snipes Shot 18: Set nl04 to 0.8 x 10^20 m^-2. Enabled the A-coils. Ip remains at 0.8 MA. Fizzle!

Jun 20 2007 01:38:51:837PM 1070620019 Joseph Snipes Shot 19: Reduced Br0 by 0.3 mT to -3.3 mT. Fizzle!

Fizzle.

Jun 20 2007 03:53:51:690PM 1070620029 Joseph Snipes Shot 29: Try again. Good shot. Something disrupts the plasma at 1.48 s though Brock swears it was not a Li
pellet. Large MARFE between 0.6 and 0.8 s.

Jun 20 2007 04:01:45:447PM 1070620030 Joseph Snipes Shot 30: Reduced nl04 to 1 x 10^20 m^-2 and set the time to reach flattop density at 0.65 s. Reduced prepuff
to 14 ms duration. Good shot. Disrupted at 1.48 s but this time Brock is taking the blame.

Jun 20 2007 03:53:51:690PM	1070620029	Joseph Snipes	Shot 29: Try again. Good shot. Something disrupts the plasma at 1.48 s though Brock swears it was not a Li pellet. Large MARFE between 0.6 and 0.8 s.
Jun 20 2007 04:01:45:447PM	1070620030	Joseph Snipes	Shot 30: Reduced nl04 to 1 x 10^20 m^-2 and set the time to reach flattop density at 0.65 s. Reduced prepuff to 14 ms duration. Good shot. Disrupted at 1.48 s but this time Brock is taking the blame.
Jun 20 2007 04:10:06:327PM	1070620030	Joseph Snipes	Delay to replace fuses on the ICRF.
