Day 1 of Liang Lin's plan for ohmic runs.
Shot plan laid out in E mail, but Ian will tune in the shots as appropriate. Perhaps starting with higher density and lower it toward 2x10^19.
We should avoid runaways to the extent possible.
B=5.2T to start with and Ip=600 kA.

Everything went very well today.
The summary of good shots and parameters had been placed by Liang Lin in the PCI summary. Please refer to it for further information regrading tody's run.
Tomorrow we will run two sets of plasmas, one at 3.9 T at 0.6 MA,
and another set at 2.6 T and 0.4MA at various densities that will be specified tomorrow and what is needed to complete the data set. HIREX SR collected data, as well as the GPI was running. The laser blow-off dropped out earlier in the morning due to a closed gate-valve.

PO summary 15 Dec 09
--------------------
MP571 Low density ohmic plasmas.

We used 3T initiation throughout; for both 5.2 and 2.6 T fields, with
appropriate field ramps after breakdown, and early diversion. We had
a rather high OH coax resistance after two low current disruptions the
first two shots. A rather slow trend over the whole day brought the
resistance back to about 2.5 micro ohms.

The initiation was very reliable, with one dud that appeared to be
caused by a 20A jump in EF4L, and a post disruption fizzle.

The entire first day of the shot list was covered, although it proved
impossible to avoid locked modes and disruptions for the lowest
densities (.2 and .3) at 1MA. Having the cryopump made density control
quite easy at the low densities desired. It was, as expected
impossible to avoid runaways. Their levels were variable.

In addition, the 5.2T part of day 2 was also covered (higher densities)
at the request of the SL.

Thus all that is left to do for tomorrow is 1-14 of the Dec 16 shot
list. Those are the 3.9 and the 2.6T field plasmas.

Session Leader Comments

Dec 15 2009 10:29:44:207AM 1091215001 Miklos Porkolab Day 1 of ohmic run for Liang Lin.
Collect more data for linear ohmic regime transport at low densities.
PCI is set to medium to low k regime (k < 15 cm-1).Timing is set to 0.8-1.4 sec.
BT = 5.2 T, Ip= 400 kA.
Proposed shots will include additional special diagnostics as follows:
at 1.30 sec, on selected shots, Nathan Howard will inject CaF2 with the laser blow-off to collect information on particle transport at low densities.
Following this, perhaps 50 ms later, there will be GPI injections (Istvan Cziegler, Jim Terry) to collect data on edge turbulence at low densities (like to see if it has different features than the PCI).
The proposed shot sequence is as follows:
1. Start with a shot like 1090918012 at Bt = 5.2 T, Ip = 0.4 MA, target density of nl04 = 0.2. Runaways are expected. Check TS to see if spatial coverage is optimized. Repeat until good data is obtained.Increase density if necessary.
2. Increase current , Bt= 5.2 T, Ip = 0.6 MA. Keep density at nl04 = 0.2.
3. Repeat to improve on the runaway situation.
4. Move on to Bt= 2.6 T, Ip = 0.4 MA. Keep density at nl04 = 0.2.
Runaways are expected. Two or three shots might be necessary to get to target Bt and Ip.
5. Move to Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.25. Runaways should be mitigated.
6.Repeat shot as necessary for good data.
7. Move to Bt = 2.6 T, Ip = 0.4 MA, nl04 = 0.25. Repeat shot as necessary for good data.
8. Move to Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.30. Expect no runaways. Repeat as necessary.
9. Move to Bt = 5.2T, Ip = 0.6 MA, nl04 = 0.30. Repeat as necessary.
10. Move to Bt = 2.6T, Ip = 0.4 MA, nl04 = 0.30. Expect no runaways. Rrepeat.

Lower Priority sequence of shots:
11. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.20. Expect locked modes but shot useful at earlier times.
12. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.30.
13. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.40.
14. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.50.
15. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.60.
End of today's plan. Will continue on the 16th , starting at 3.9 T.
Prepare for overnight ECDC.

Dec 15 2009 10:43:00:127AM 1091215008 Miklos Porkolab Density rising slowly from nl04 = 0.25 at 0.8 sec to 0.30 at 1.6 sec.
Bt = 5.37 T, Ip= 0.63 MA.

Dec 15 2009 11:14:17:830AM 1091215010 Miklos Porkolab Bt = 5.39T, Ip= 0.63 MA, nl04 = 0.2. Still runaways. Will try to raise the density to give Amanda a thermal plasma for a calibration shot for ECE.

Dec 15 2009 11:30:53:410AM 1091215011 Miklos Porkolab Bt = 5.2 T, Ip = 0.62 MA, nl04 = 0.3. Still substantial runaways.
Will need to raise the density further to calibrate ECE.

Dec 15 2009 11:42:24:597AM 1091215012 Miklos Porkolab Excellent shot. Thermal mostly. Good enough for ECE calibration.
Bt= 5.2 T, Ip= 0.62 MA, nl04 = 0.30.
Next shot target plasma will be at 2.6 T, Ip = 0.4 MA, nl04 = 0.3.

Dec 15 2009 12:11:05:393PM 1091215013 Miklos Porkolab Bt= 2.7 T, Ip = 0.4 MA, nl04 = 0.21E20.
Good shot.

Dec 15 2009 12:14:24:363PM 1091215014 Miklos Porkolab Good shot. Some hard Xrays.
Bt= 2.7 T, Ip= 0.4 MA, nl04 = 0.20.
Lost CaF2 injector some time ago due to closed gatevalve (at which shot ?)

Dec 15 2009 12:24:54:753PM 1091215015 Miklos Porkolab Bt= 2.7 T, nl04 = 0.25, Ip = 0.4 MA. Fewer hard X rays this time.

Dec 15 2009 12:33:19:330PM 1091215016 Miklos Porkolab Bt= 2.7 T, nl04 = 0.30, Ip = 0.4 MA. More Argon injected.

Dec 15 2009 12:53:03:097PM 1091215017 Miklos Porkolab Did Bt = 2.7 T, Ip = 0.4 MA, nl04 = 0.28.
With this shot we are done with the 2.7 T shot sequence
(including Liang's reference shot 17, 18).
We shall now return to Bt = 5.2 T, Liang's reference shot 7.

Dec 15 2009 01:02:14:783PM 1091215018 Miklos Porkolab Bt= 5.2 T, Ip = 0.4 MA, nl04 = 0.2E20. Runaways mild to small.
Will repeat shot.

Dec 15 2009 01:16:03:067PM 1091215019 Miklos Porkolab Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.25. Lot more Hard Xrays than before.

Dec 15 2009 01:28:06:887PM 1091215020 Miklos Porkolab This was basically a repeat shot from 19.
Will increase the density on the next shot.

Dec 15 2009 02:00:09:640PM 1091215022 Miklos Porkolab Good shot after the dud on the previous shot.
Bt = 5.2 T, nl04 = 0.31E20, Ip = 0.4 MA.
Apparently there was no Thomson so shot needs to be repeated.

Dec 15 2009 02:17:34:327PM 1091215023 Miklos Porkolab Good shot.
Bt= 5.2 T, Ip = 0.42 MA, nl04 = 0.3E20.
Thomson OK this time.

Dec 15 2009 02:24:58:563PM 1091215024 Miklos Porkolab Tried 5.2 T, Ip = 1.0 MA. Got disruption at 0.8 sec (locked mode ?).
Density too high, nl04 = 0.5E20 .

Dec 15 2009 02:39:03:487PM 1091215025 Miklos Porkolab Repeat previous shot. Locked mode disrupts again at about 0.65 sec.
Density lower this time, nl04 = 0.25E20. Bt = 5.2 T.

Dec 15 2009 02:52:38:407PM 1091215026 Miklos Porkolab Got locked mode again but now at 0.5 sec.
Will try to go to higher density next shot.

Dec 15 2009 03:09:47:593PM 1091215027 Miklos Porkolab Still at 5.2 T, 1 MA. Fizzle ?

Dec 15 2009 03:22:17:500PM 1091215028 Miklos Porkolab Good shot, enormous amounts of runaway,but did not disrupt. Good for shot 21 of Liang's series, Bt= 5.2T, Ip = 1.0 MA, nl04 = 0.4E20.
Moving up in density on the next two shots, trying to match Liang's 22,23.

Dec 15 2009 03:33:15:330PM 1091215029 Miklos Porkolab Even better shot, still runaways but now reduced significantly at the higher density. Bt = 5.2 T, Ip= 1.0 MA, nl04 = 0.5E20.

Dec 15 2009 03:42:56:767PM 1091215030 Miklos Porkolab Very nice thermal shot. Good for ECE calibration.
Bt = 5.2 T, Ip = 1.0 MA, nl04 = 0.6E20.

Dec 15 2009 04:03:17:157PM 1091215031 Miklos Porkolab Ok, got injection at 0.8 sec and disrupted.
Bt = 5.2T, Ip = 1.0 MA, nl04 = 0.35 at t= 0.6-0.7 sec.
Next going to lower currents, from the runplan of tomorrow,
namely, Bt=5.2 T, Ip = 0.4, 0.6 MA, nl04 = 0.4, 0.5, 0.6.

Dec 15 2009 04:22:38:390PM 1091215032 Miklos Porkolab Bagan low current, high density campaign from tomorrow's runplan.
Bt = 5.2 T, Ip = 0.6 MA, nl04 = 0.4E20.
Runaways present but ramping down with time. Best conditions at 1.0-1.5 sec
for potential confinement studies.

Dec 15 2009 04:26:48:563PM 1091215033 Miklos Porkolab Good shot. Bt = 5.2 T, Ip = 0.6 MA, nl04 = 0.5 - 0.6E20 for t= 0.8-1.4 sec.
Had PCI on from 0.8 - 1.4 sec. This covers densities 0.5,0.6 at this current.
Pretty thermal plasma, without any x rays from 0.8 to1.4 sec.
We will next drop current to 0.4 MA

Dec 15 2009 04:40:07:250PM 1091215034 Miklos Porkolab Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.55E20. Good shot.
X-rays negligible from 1.0 - 1.4 sec.
Use this for transport analysis. PCI covers time range 0.8-1.4 sec.
Will lower density on next shot, same current and Bt.

Dec 15 2009 04:55:39:157PM 1091215035 Miklos Porkolab Good shot.
Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.40E20 at 1.0 sec, and pretty steady at 0.5-1.0 sec, with a slight minimum at 0.37 at 1.25 sec into the pulse.
No hard xrays. PCI covers 0.8-1.4 sec.

Session Leader Comments
Dec 15 2009 10:29:44:207AM	1091215001	Miklos Porkolab	Day 1 of ohmic run for Liang Lin. Collect more data for linear ohmic regime transport at low densities. PCI is set to medium to low k regime (k < 15 cm-1).Timing is set to 0.8-1.4 sec. BT = 5.2 T, Ip= 400 kA. Proposed shots will include additional special diagnostics as follows: at 1.30 sec, on selected shots, Nathan Howard will inject CaF2 with the laser blow-off to collect information on particle transport at low densities. Following this, perhaps 50 ms later, there will be GPI injections (Istvan Cziegler, Jim Terry) to collect data on edge turbulence at low densities (like to see if it has different features than the PCI). The proposed shot sequence is as follows: 1. Start with a shot like 1090918012 at Bt = 5.2 T, Ip = 0.4 MA, target density of nl04 = 0.2. Runaways are expected. Check TS to see if spatial coverage is optimized. Repeat until good data is obtained.Increase density if necessary. 2. Increase current , Bt= 5.2 T, Ip = 0.6 MA. Keep density at nl04 = 0.2. 3. Repeat to improve on the runaway situation. 4. Move on to Bt= 2.6 T, Ip = 0.4 MA. Keep density at nl04 = 0.2. Runaways are expected. Two or three shots might be necessary to get to target Bt and Ip. 5. Move to Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.25. Runaways should be mitigated. 6.Repeat shot as necessary for good data. 7. Move to Bt = 2.6 T, Ip = 0.4 MA, nl04 = 0.25. Repeat shot as necessary for good data. 8. Move to Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.30. Expect no runaways. Repeat as necessary. 9. Move to Bt = 5.2T, Ip = 0.6 MA, nl04 = 0.30. Repeat as necessary. 10. Move to Bt = 2.6T, Ip = 0.4 MA, nl04 = 0.30. Expect no runaways. Rrepeat. Lower Priority sequence of shots: 11. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.20. Expect locked modes but shot useful at earlier times. 12. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.30. 13. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.40. 14. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.50. 15. Bt= 5.2 T, Ip = 1.0 MA, nl04 = 0.60. End of today's plan. Will continue on the 16th , starting at 3.9 T. Prepare for overnight ECDC.
Dec 15 2009 10:43:00:127AM	1091215008	Miklos Porkolab	Density rising slowly from nl04 = 0.25 at 0.8 sec to 0.30 at 1.6 sec. Bt = 5.37 T, Ip= 0.63 MA.
Dec 15 2009 11:14:17:830AM	1091215010	Miklos Porkolab	Bt = 5.39T, Ip= 0.63 MA, nl04 = 0.2. Still runaways. Will try to raise the density to give Amanda a thermal plasma for a calibration shot for ECE.
Dec 15 2009 11:30:53:410AM	1091215011	Miklos Porkolab	Bt = 5.2 T, Ip = 0.62 MA, nl04 = 0.3. Still substantial runaways. Will need to raise the density further to calibrate ECE.
Dec 15 2009 11:42:24:597AM	1091215012	Miklos Porkolab	Excellent shot. Thermal mostly. Good enough for ECE calibration. Bt= 5.2 T, Ip= 0.62 MA, nl04 = 0.30. Next shot target plasma will be at 2.6 T, Ip = 0.4 MA, nl04 = 0.3.
Dec 15 2009 12:11:05:393PM	1091215013	Miklos Porkolab	Bt= 2.7 T, Ip = 0.4 MA, nl04 = 0.21E20. Good shot.
Dec 15 2009 12:14:24:363PM	1091215014	Miklos Porkolab	Good shot. Some hard Xrays. Bt= 2.7 T, Ip= 0.4 MA, nl04 = 0.20. Lost CaF2 injector some time ago due to closed gatevalve (at which shot ?)
Dec 15 2009 12:24:54:753PM	1091215015	Miklos Porkolab	Bt= 2.7 T, nl04 = 0.25, Ip = 0.4 MA. Fewer hard X rays this time.
Dec 15 2009 12:33:19:330PM	1091215016	Miklos Porkolab	Bt= 2.7 T, nl04 = 0.30, Ip = 0.4 MA. More Argon injected.
Dec 15 2009 12:53:03:097PM	1091215017	Miklos Porkolab	Did Bt = 2.7 T, Ip = 0.4 MA, nl04 = 0.28. With this shot we are done with the 2.7 T shot sequence (including Liang's reference shot 17, 18). We shall now return to Bt = 5.2 T, Liang's reference shot 7.
Dec 15 2009 01:02:14:783PM	1091215018	Miklos Porkolab	Bt= 5.2 T, Ip = 0.4 MA, nl04 = 0.2E20. Runaways mild to small. Will repeat shot.
Dec 15 2009 01:16:03:067PM	1091215019	Miklos Porkolab	Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.25. Lot more Hard Xrays than before.
Dec 15 2009 01:28:06:887PM	1091215020	Miklos Porkolab	This was basically a repeat shot from 19. Will increase the density on the next shot.
Dec 15 2009 02:00:09:640PM	1091215022	Miklos Porkolab	Good shot after the dud on the previous shot. Bt = 5.2 T, nl04 = 0.31E20, Ip = 0.4 MA. Apparently there was no Thomson so shot needs to be repeated.
Dec 15 2009 02:17:34:327PM	1091215023	Miklos Porkolab	Good shot. Bt= 5.2 T, Ip = 0.42 MA, nl04 = 0.3E20. Thomson OK this time.
Dec 15 2009 02:24:58:563PM	1091215024	Miklos Porkolab	Tried 5.2 T, Ip = 1.0 MA. Got disruption at 0.8 sec (locked mode ?). Density too high, nl04 = 0.5E20 .
Dec 15 2009 02:39:03:487PM	1091215025	Miklos Porkolab	Repeat previous shot. Locked mode disrupts again at about 0.65 sec. Density lower this time, nl04 = 0.25E20. Bt = 5.2 T.
Dec 15 2009 02:52:38:407PM	1091215026	Miklos Porkolab	Got locked mode again but now at 0.5 sec. Will try to go to higher density next shot.
Dec 15 2009 03:09:47:593PM	1091215027	Miklos Porkolab	Still at 5.2 T, 1 MA. Fizzle ?
Dec 15 2009 03:22:17:500PM	1091215028	Miklos Porkolab	Good shot, enormous amounts of runaway,but did not disrupt. Good for shot 21 of Liang's series, Bt= 5.2T, Ip = 1.0 MA, nl04 = 0.4E20. Moving up in density on the next two shots, trying to match Liang's 22,23.
Dec 15 2009 03:33:15:330PM	1091215029	Miklos Porkolab	Even better shot, still runaways but now reduced significantly at the higher density. Bt = 5.2 T, Ip= 1.0 MA, nl04 = 0.5E20.
Dec 15 2009 03:42:56:767PM	1091215030	Miklos Porkolab	Very nice thermal shot. Good for ECE calibration. Bt = 5.2 T, Ip = 1.0 MA, nl04 = 0.6E20.
Dec 15 2009 04:03:17:157PM	1091215031	Miklos Porkolab	Ok, got injection at 0.8 sec and disrupted. Bt = 5.2T, Ip = 1.0 MA, nl04 = 0.35 at t= 0.6-0.7 sec. Next going to lower currents, from the runplan of tomorrow, namely, Bt=5.2 T, Ip = 0.4, 0.6 MA, nl04 = 0.4, 0.5, 0.6.
Dec 15 2009 04:22:38:390PM	1091215032	Miklos Porkolab	Bagan low current, high density campaign from tomorrow's runplan. Bt = 5.2 T, Ip = 0.6 MA, nl04 = 0.4E20. Runaways present but ramping down with time. Best conditions at 1.0-1.5 sec for potential confinement studies.
Dec 15 2009 04:26:48:563PM	1091215033	Miklos Porkolab	Good shot. Bt = 5.2 T, Ip = 0.6 MA, nl04 = 0.5 - 0.6E20 for t= 0.8-1.4 sec. Had PCI on from 0.8 - 1.4 sec. This covers densities 0.5,0.6 at this current. Pretty thermal plasma, without any x rays from 0.8 to1.4 sec. We will next drop current to 0.4 MA
Dec 15 2009 04:40:07:250PM	1091215034	Miklos Porkolab	Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.55E20. Good shot. X-rays negligible from 1.0 - 1.4 sec. Use this for transport analysis. PCI covers time range 0.8-1.4 sec. Will lower density on next shot, same current and Bt.
Dec 15 2009 04:55:39:157PM	1091215035	Miklos Porkolab	Good shot. Bt = 5.2 T, Ip = 0.4 MA, nl04 = 0.40E20 at 1.0 sec, and pretty steady at 0.5-1.0 sec, with a slight minimum at 0.37 at 1.25 sec into the pulse. No hard xrays. PCI covers 0.8-1.4 sec.

Physics Operator Comments
Dec 15 2009 09:04:03:987AM		Ian Hutchinson	Load from 1091117022. Low field controlled startup. This was using segments 1 3. Load seg 2 from 1090918012. Needs magnetics predictors called. Call predictors. Load. Warning about wire 11 zeroed in seg 15. Use seg 2, not 3. Start at 0.08s. Get engineering settings changed appropriately. Segment 2. Adjust early current to .4MA. Argon puff is 50ms. No other puff. Nl04 is set very low. Itf is 144.5kA. Put in ramp up in seg 1 to patch. Reduce number of points of PG3 in segment 1. Fill puff to 40ms at -.3s for cryopump. Move out 80ms rcur point to .66m Seg 2. Begin clearin ramp earlier. Adjust rxl.
Dec 15 2009 09:07:49:987AM	1091215001	Ian Hutchinson	No power test.
Dec 15 2009 09:37:08:940AM	1091215002	Ian Hutchinson	Disrupts at .1s. Appears to be vertical position problem. Found issue with zcur controller not on till .9s. Made it zero. Also used load gains to get from segment 3 on wires 2 and 3. Load.
Dec 15 2009 09:47:40:550AM	1091215003	Ian Hutchinson	Disrupts at .15s Improve vertical control by load wave for RXL. Move up early zxl. Delay the clearin rampup to .2 from .175s.
Dec 15 2009 10:01:41:393AM	1091215004	Ian Hutchinson	Plasma to rampdown. Very low density and amazing runaways. Still a bit unstable. Move rcur out to mirror the other startup at .15-.2s. to stabilize further. Load gains from seg 3 to seg 2 in wire 16 Ip.
Dec 15 2009 10:19:04:753AM	1091215005	Ian Hutchinson	Plasma to rampdown. The density glitch at 1.3s is due to OH1 crossover. Bring on the OH1 crossover test pro in PCS. switch times .4,1.4. Ip to 0.6MA. Delay clearin ramp end to .22s
Dec 15 2009 10:24:20:160AM	1091215006	Ian Hutchinson	Plasma to rampdown. Lower OH1V to 200 from 250 in early segment 2. Increase Ar puff to 90ms.
Dec 15 2009 10:37:21:470AM	1091215007	Ian Hutchinson	Plasma to rampdown. Stability problem is fixed. Raise Nl04 to .25
Dec 15 2009 10:51:52:130AM	1091215008	Ian Hutchinson	Plasma to rampdown. Delay TF rampdown. nl04 final point decreased. Load wire 15 ICEF4 from segment 3.
Dec 15 2009 11:05:10:860AM	1091215009	Ian Hutchinson	Plasma disrupts at .52s. Vertical postion problem apparently as EF2s come out of zero limits. Import seg 3 to seg 3 from 1091117030. This is to check the EF2 programs. Don't use that. Just set EF2 Voltages to zero at .07s. Add a little EF2byEF4 gain at .15s.
Dec 15 2009 11:18:56:080AM	1091215010	Ian Hutchinson	Plasma to rampdown. Nl04 to .3 Lower OH1V to 150V at .1s EF2Vs to -50V at .07s EF3V to 2800 at 5ms.

Dec 15 2009 12:19:47:423PM	1091215014	Ian Hutchinson	Plasma to rampdown. NL04 to .25 Many controllers points put to 2.2s. Increase Rcur value at 2s Tweak voltages in rampdown to move slower. Still have a granularity warning.
Dec 15 2009 12:32:32:957PM	1091215015	Ian Hutchinson	Plasma to rampdown. Increase Ar. Increase NL04 to .3 Drop ef2byef4 gain at 1.8s.
Dec 15 2009 12:47:39:410PM	1091215016	Ian Hutchinson	Plasma to rampdown. NL04 to .27 Tweak some ends. Can't find granularity error.
Dec 15 2009 01:04:21:270PM	1091215017	Ian Hutchinson	Plasma to rampdown. Bt to 5.2T. NL04 to .2 Move integrator gates to 2.2s
Dec 15 2009 01:15:58:453PM	1091215018	Ian Hutchinson	Plasma to rampdown. EF3 is going to zero before EF4. Reduce ICEF4 at end. NL04 to .25
Dec 15 2009 01:26:13:100PM	1091215019	Ian Hutchinson	Plasma to rampdown. NL04 to .3 ICEF4 raised a tad to try to keep EF2s off. Loaded too late. It did not take.
Dec 15 2009 01:41:33:563PM	1091215020	Ian Hutchinson	Plasma to rampdown. Load prior changes.
Dec 15 2009 01:53:29:280PM	1091215021	Ian Hutchinson	Dud. No obvious reason. EF4L current rose by 20A from prior shots. (Not EF4U). No changes.
Dec 15 2009 01:59:20:077PM	1091215022	Ian Hutchinson	Plasma to rampdown. Apparently no TS. Repeat.
Dec 15 2009 02:19:42:703PM	1091215023	Ian Hutchinson	Plasma to rampdown. Load seg 4 from shot 11 seg 2. Standard duration shot. Set Ip to 1MA. NL04 to .2 Change references for 9-12 to 10 in preparation for B21proj adjustments. But don't yet change that. Switch to segment 4. Load.
Dec 15 2009 02:32:01:030PM	1091215024	Ian Hutchinson	Disrupts at .8s Turn off crossover. Import seg 4 to seg 2. Draw B21proj at 1.e-4 0-.5s. Switch to segment 2.
Dec 15 2009 02:48:46:123PM	1091215025	Ian Hutchinson	Plasma to .64s. Definite locked mode starting at .35s Ar puff to 60ms. B21proj start to 0.1s Increase to 1.5Gauss.
Dec 15 2009 03:01:37:063PM	1091215026	Ian Hutchinson	Plasma disrupts at .5s. Locks a bit earlier. NL04 to .4. RXL moved out to try to avoid the slot divertor early.
Dec 15 2009 03:12:03:940PM	1091215027	Ian Hutchinson	Fizzle. Repeat.
Dec 15 2009 03:29:40:737PM	1091215028	Ian Hutchinson	Plasma to rampdown. Apparently not locked. NL04 to .5
Dec 15 2009 03:40:44:280PM	1091215029	Ian Hutchinson	Plasma to rampdown. NL04 to .6
Dec 15 2009 03:53:39:767PM	1091215030	Ian Hutchinson	Plasma to rampdown. Program NL04 to peak at .45 and ramp down to .2
