Session leader plan for 1120215 Session Leader: G. Wallace Physics Operator: W. Rowan MP: 605 LH2 Lower Hybrid Launcher Checkout and Conditioning LH Setup: Launcher ~3 mm behind GH limiter (1290 counts on PLC); 90 degree current-drive phasing; 200-1000 kW net power (~70-200 kW/klystron); LH on from 0.8 to 1.3s. Reference shot: 1120127024 (5.4 T, 700 kA, USN) Shot Plan: 1) Begin with co-current 90 degree ideal phasing. Set power level to 80 kW/klystron (half on direct fed columns) at 40 kV. Set pulse length to 0.5 s. 2) Increase power in increments of 10-20 kW/klystron. Pay particular attention to LH camera view. If arcing occurs, reduce power to last "safe" level and begin raising power again. 3) Adjust radial position of plasma and/or launcher if breakdown on grill mouth does not improve.

This was a difficult day, and the experiment was not accomplished, due to difficulties with LHCD, data system issues, and machine issues. None of the required scans could be performed at the necessary powers. Nevertheless, some useful data were found. A 3 point current scan of locked modes was performed and it seems that the current does not affect the HiReX calibration significantly. More detailed analyses of these discharges are required to test the HireX Sr calibraiton. A single current scan at nl04~0.4E20 was performed, with the low current case not reproducing the previously observed results. This suggests that there may be a temperature affect in the LHCD rotation reversal, perhaps related through the collisionality. It was attempted to bring up the LHCD power late in the day to confirm this effect, and a few useful shots were taken with the rotation reversal point being identified at 600 kW at 500 kA. Higher density with 600 kW of LHCD at 500 kA was attempted, but it was not successful. There appears to be more than originally met the eye with the LHCD induced rotation changes, seemingly on the collisionality side of things. Thank you everyone for sticking with this run.

The run was for MP 633: Lower Hybrid Current Drive induced rotation at Different Magnetic Geometries (SL Podpaly) which was to be executed during LH conditioning: MP: 605 LH2 Lower Hybrid Launcher Checkout and Conditioning (SL Wallace) The requested discharges were easily acquired and ran well. The discharges for MP 633 consisted of a narrow scan in current (0.4 MA to 0.7 MA) and density in USN configuration at 5.4 T. The cryo pump was in use. Some data was acquired for MP 633 but more is required. The LH appears to require additional conditioning. While the LH group was diagnosing control problems, there was an opportunity to continue the locked mode rotation calibration for a few extra shots. The locked mode shots are in the range 001 - 005. For some shots (009-012), a current dither was added in the last 100 ms of the current flattop for polarimeter calibration. There was a delay at the beginning of the run due to computer control of the LH. The run was extended to make up some of the lost time. A few shots were lost due to IGOR being stuck. A TF crowbar occurred late in the run. 23 plasma 03 engineering: 007(no power shot),018(TF crowbar,019 (test via plc) ---------- 26 total

Session Leader Comments
Feb 15 2012 09:14:00:380AM	1120215001	Yuri Podpaly	Start with 700 kA, standard flattop, USN, nl04=0.4E20, LHCD at 0.8 for 500 ms at 800 kW (n||=1.6) or as close as is possible. Lower Hybrid having some digitizer issues. Contingency: locked mode first Result: locked but HiReX Sr is low. LHCD still having issues and the RGA readings are off. Also Josh says to wait for the next shot. Next: Repeat locked mode pending LHCD
Feb 15 2012 09:52:12:263AM	1120215002	Yuri Podpaly	Locked mode with increased argon voltage. Result: Locked mode; argon is much better. B side lower still looks choppy. Disrupts at 1.5 sec. Next: LHCD is down for at least half an hour. Setting up 900 kA locked mode to test Sr sensitivity to locked modes.
Feb 15 2012 09:59:41:077AM	1120215003	Yuri Podpaly	900 kA locked mode. Result:Looks like it locked. Helium like system is behaving strangely. Next: 700 kA locked mode.
Feb 15 2012 10:31:19:247AM	1120215004	Yuri Podpaly	700 kA locked mode. Run has been extended to 6PM so we can have a full LH run. Thank you everyone. Result:Locked. Good data Next: 900 kA locked mode. Still waiting for LHCD.
Feb 15 2012 10:47:50:757AM	1120215005	Yuri Podpaly	900 kA locked mode. Result:Locked Next: LHCD.
Feb 15 2012 12:28:29:440PM	1120215006	Yuri Podpaly	700 kA discharge at nl04-0.4, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 800 kW Result: LHCD still working up in power. Surprisingly large amount of rotation for this power level. Next: Repeat with same power to avoid injections.
Feb 15 2012 12:49:18:640PM	1120215007	Yuri Podpaly	Target: 700 kA discharge at nl04-0.4, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 800 kW Result: Igor hung. No power shot. Next: try again. Apparently, we are taking shot 7 again. Result: IGOR problems again. Next: Take shot 7 again.
Feb 15 2012 01:06:16:250PM	1120215008	Yuri Podpaly	Target: 700 kA discharge at nl04-0.4, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 800 kW Result: nice clean LHCD at P = 300 kW Next: try again with more power
Feb 15 2012 01:19:25:260PM	1120215009	Yuri Podpaly	Target: 700 kA discharge at nl04-0.4, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 800 kW Result:very late disruption. LHCD has some issues but gets about 500 kW in. Next: try again with whatever LH needs.
Feb 15 2012 01:33:46:100PM	1120215010	Yuri Podpaly	Target: 700 kA discharge at nl04-0.4, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 800 kW Result:disruption. Bright spot seen on WIDE 2 before disruption. Next: stay at 500 kW of LHCD. Drop current to 550 kA.
Feb 15 2012 02:02:39:410PM	1120215011	Yuri Podpaly	Target: 550 kA discharge at nl04-0.4, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 500 kW Result: worked. DV = -7 kms Next: 400 kA
Feb 15 2012 02:03:00:960PM	1120215012	Yuri Podpaly	Target: 400 kA discharge at nl04-0.4, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 500 kW Result: LHCD was tripping too much. Next: repeat
Feb 15 2012 02:20:52:780PM	1120215013	Yuri Podpaly	Target: 400 kA discharge at nl04-0.4, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 500 kW Result: Good shot but the rotation is not consistent with our previous results Next: IP -> 350 kA.
Feb 15 2012 02:38:07:347PM	1120215014	Yuri Podpaly	Target: 350 kA discharge at nl04-0.4, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 500 kW Result: Really bizarre shot. Next: Let's not do that again. nl04->0.3E20, ip->400kA.
Feb 15 2012 02:51:27:923PM	1120215015	Yuri Podpaly	Target: 400 kA discharge at nl04-0.3, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 500 kW Result: not so great LHCD Next: try again.
Feb 15 2012 03:24:24:117PM	1120215016	Yuri Podpaly	Target: 400 kA discharge at nl04-0.3, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 500 kW Result: no LHCD. Next: Cut the argon to 75 ms. Try again.
Feb 15 2012 03:29:08:143PM	1120215017	Yuri Podpaly	Target: 400 kA discharge at nl04-0.3, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 500 kW Result: still difficulties with LHCD. Possible marfing? Hard to say what is happening with rotation with so many things going on. Next: Turn off the argon. Move LHCD to 1.0-1.5 seconds.
Feb 15 2012 04:23:04:180PM	1120215018	Yuri Podpaly	Target: 400 kA discharge at nl04-0.3, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = 500 kW Result: TF crowbar Next: repeat. Argon to 35 ms. There is really insufficient time to complete these scans. We will try to get the LHCD power up and see if there is a collisionality effect with the LHCD rotation reversal.
Feb 15 2012 04:26:17:937PM	1120215019	Yuri Podpaly	PLC test Next: repeat shot 17 and try to bring up the LHCD power to 800 kW in future shots.
Feb 15 2012 04:42:23:687PM	1120215020	Yuri Podpaly	Target: 400 kA discharge at nl04-0.3, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = as high as it can go Result: Tripping LHCD Next: repeat try to get the LHCD up.
Feb 15 2012 05:06:44:233PM	1120215021	Yuri Podpaly	Target: 400 kA discharge at nl04-0.3, with 500 ms of LHCD at 0.8s n||=1.6, PLHCD = as high as it can go Result: Tripping LHCD. Something came out of the launcher. Next: repeat try to get the LHCD. Increase argon to 40. Scratch that. Fiducial LHCD shot to see if things are still ok with LHCD.
Feb 15 2012 05:13:29:860PM	1120215022	Yuri Podpaly	LHCD trips out on a known good shot Next: do what Greg says to do.
Feb 15 2012 05:36:32:030PM	1120215023	Yuri Podpaly	LHCD runs for 700 ms. Next: 500 kA try to get some power in.
Feb 15 2012 05:47:46:250PM	1120215024	Yuri Podpaly	LHCD ran. No rotation change at 500 kA with 600 kW of LHCD. Next: nl04-> 0.5E20
Feb 15 2012 06:02:03:050PM	1120215025	Yuri Podpaly	LHCD tripped out Next: Last shot and density trace was low.
Feb 15 2012 06:14:56:547PM	1120215026	Yuri Podpaly	Marfing Last shot. Thank you everyone.
