All these discharges are 450 kA, ramped up in 500 ms. Performed the LH and LH+ICRF sections of this MP. Generated discharges with only LH injection in the ramp at various densities. This indicates that densities above 5.5e19 appear to damp out the fast electrons before the LH pulse is over, while densities below this allow fast electrons to exist for the whole LH pulse. Unfortunately this is also the break point in the density value to get ICRF H-modes in the ramp. LH powers of 500-700 kW were the most reliable. ICRF at powers of 2 MW or more routinely produced H-modes in the flattop. Using ICRF at low density in the ramp was a problem, causing radiative Te collapses. Although it appears that the E antenna was responsible, it was unclear in the end, since some of it remained after E was turned off. Attempts to ramp the density and ramp the ICRF power did not work much. Finally using low density up to 350 ms to enhance the LHCD, and then rampup the density and inject ICRF to enter an H-mode at about 300-350 ms worked. The high densities required to get H-mode in the rampup were not compatible with the LH, and the low densities required for LH fast electrons to persist were not compatible with the ICRF H-mode formation in the ramp. Sawteeth generally appear at 150 ms for the ohmic discharges, and these were delayed up to 550 ms with LH alone, to 625 ms with L-mode and low power ICRF and LH, and out to 875 ms with high power ICRF (Te collapse) and LH. When high densities were used to get ICRF H-mode in the ramp, the sawteeth were delayed to 500 ms.

Author: Ron Parker

The run got off to a slow start due to a power glitch that occured just as boronization was shutting down in preparation for ecdc (~ 4:00 AM). First plasma attempt occured at 9:45, and fizzled due to the fact that the cryo pump was not pumping, resulting in the fill pressure being too high. (The setup assumed that the pump would be on.) After one more fizzle, shot 3 ran full length as did most of the shots for the rest of the run. The shots for this run were based on a single lower null equilibrium with 450 kA current. Density, ICRF and LH power, and the relative timing, were varied throught the day. The objective was to use LHCD for startup, and freeze a q>1 profile with ICRF which would also form an H-Mode. The basic difficulty was the high density rise associated with H-Mode onset eliminates the effectiveness of LHCD. Also the short resistive diffusion time, ~ 100-200 ms, does not allow for a long H-Mode with q > 1. See C. Kessel's summary for details. As for the machine: 26 attempts at plasma, 2 fizzles (as mentioned due to finding the right fill gas level at the beginning of the run), 2 disruptions (nevertheless useful for obtaining data), and 22 full length shots.

Physics Operator Comments
Feb 21 2008 09:49:36:163AM	1080221003	Ron Parker	There was a power glitch this AM, which delayed the start of today's run. After two no-power shots, the first plasma attempt occured at ~ 9:45. Unfortunately, the cryopump was not ready and the fill gas pressure, which had been set for operation with the cryo, was too high leading to a fizzle.
Feb 21 2008 10:05:50:480AM	1080221004	Ron Parker	Another fizzle, but more vigorous than hte first. Looks like a more gas would be helpful --raise PG to 55 from 45 ms for next shot.
Feb 21 2008 10:19:59:480AM	1080221005	Ron Parker	Shot 5 went off with a bouncing startup. Next: repeat shot 5 with LH.
Feb 21 2008 10:42:03:583AM	1080221006	Ron Parker	Shot 6 went off OK, but LH had only trips.
Feb 21 2008 10:49:48:543AM	1080221007	Ron Parker	Shot 7 was full length, LH had several trips before staying on from 0.45 s to ~ 0.5 s, and 0.54 s to 0.7 s.
Feb 21 2008 11:37:44:680AM	1080221008	Ron Parker	Delay was due to cell access to fix camera view of LH grill. Shot 8 ran OK. About 0.2 V reduction in loop voltage due to LH.
Feb 21 2008 11:38:39:867AM	1080221009	Ron Parker	Shot 9 ran OK, LH power up to 500 + kW.
Feb 21 2008 12:23:14:920PM	1080221010	Ron Parker	Shot 10 was fine, LH ran uninterupted. Long sawtooth delay.
Feb 21 2008 12:37:21:293PM	1080221011	Ron Parker	Shot 11 disrupted during ICRF pulse.
Feb 21 2008 12:37:53:827PM	1080221012	Ron Parker	Shot 12 disrupted again at 1 s.
Feb 21 2008 04:15:12:357PM	1080221013	Ron Parker	Shot 13 ran full length, but both LH and ICRF were choppy.
Feb 21 2008 01:15:00:087PM	1080221014	Ron Parker	Granetz substituting for Ron as physics operator for the next hour.
Feb 21 2008 01:15:23:027PM	1080221014	Ron Parker	Shot 14 was fine, LH ran uninterrupted. Next shot: change LH and ICRF timing. Also turn on NINJA D2 puffing after t=1.0 s for Kenny Marr. (Logbook entry made by Granetz)
Feb 21 2008 01:55:27:057PM	1080221015	Ron Parker	Shot 15 was fine, LH only faulted twice. Next shot: repeat, no DPCS changes (logbook entry made by Granetz)
Feb 21 2008 01:36:48:067PM	1080221016	Ron Parker	Shot 16 was fine. This shot and the previous shot both had a large drop in Te around t=0.5 s; not sure why. Next shot: reduce early ICRF power (Logbook entry made by Granetz)
Feb 21 2008 01:58:27:573PM	1080221017	Ron Parker	Shot 17 was fine, LH faulted after t=0.6 s. P_ICRF was about 1.1 MW until t=0.5 s, then jumped up to 2.6 MW as desired. The large, early drop in Te is gone. Next shot: repeat, except enable the argon valve and program in a 100 ms puff starting at t=0.3 s. ICRF power will stay down at 1 MW for the entire pulse. (logbook entry made by Granetz)
Feb 21 2008 02:10:08:057PM	1080221018	Ron Parker	Shot 18 was fine, LH had one fault. Didn't get an H-mode at the lower ICRF power. Next shot: raise nl_04 to 4e19 m-2. Also turn the ICRF power back up to 2.6 MW after t=0.5 s. (logbook entry made by Granetz)
Feb 21 2008 02:26:01:623PM	1080221019	Ron Parker	Shot 19 was fine, LH faulted after t=0.6 s. P_ICRF = 2.6 MW after t=0.5 s. Target nl_04 was 4.e19 m-2, as desired. Ron is back and will take over as physics operator now. (logbook entry made by Granetz)
