Run plan for 1091210 SL: Rich Groebner, Jerry Hughes PO: Earl Marmar Prep: -- Overnight boronization followed by He ECDC -- Working Gas Species: Deuterium -- ICRF at 80 MHz up to 3 MW available. (Mainly D+E. Will use J-port if necessary) -- Special gas puffing: 1psi Ar puff enabled, puff at 0.3s, 50ms in length 10psi D2 NINJA puff enabled for GPI, CXRS -- A-Coils: Standard configuration Desired Diagnostics and their set up: 1.) Edge TS. Adjust position of fibers for discharge 1090902012. Crown of plasma is weakly shaped. Be ready to adjust pulse timing shot to shot. 2.) ECE. Setup as on 1090902, to get fast measurements near pedestal top. 3.) PCI. Unmasked configuration, digitizing for full length of discharge. Calibrate fluctuation amplitude on each shot. 4.) Fast magnetics. Digitize for full length of shot. 4.) Reflectometer. Set 0.5s digitization window to begin at 0.45s. 5.) GPI. 6.) Passive and GP-assisted CXRS. 7.) Bolometry. 8.) Lyman alpha. Run plan: 1. Load from 1090902012. Lower nl04 demand to 0.8e20. Begin with flat ICRF pulse of 2MW from 0.5s to 1.5s, for the purposes of recovering from boronization. When sufficient ICRF power is injected, EDA H-modes are expected. 2. When steady conditions are obtained, modify ICRF waveform to include a power ramp from 0.8 to 1.3s. Observe pedestal and fluctuation response. a.) Ramp power up to 3MW. b.) Ramp power down to 1MW. Puff D2 for GPI and CXRS at 1.3s, to check out these diagnostics. 3. Next, go to reproducing identical L-H transitions. ICRF will fire at a modest level, probably 2MW, in pulses of 150ms duration, with 150ms gaps in between: [0.50,0.65],[0.80,0.95],[1.10,1.25],[1.40,1.55]. Vary TS timing as needed to fill in the time history of the pedestal formation with pedestal data. Monitor fluctuations and other diagnostics. Puff for GPI and CXRS on last H-mode in series. 4. Raise current to 1.0MA. Raise nl04 to 1e20. Repeat step 2 and determine whether there is a power level that gives a good pedestal collisionality match to the EDA H-modes in step 3. 5. Repeat step 3 with an appropriately chosen level of ICRF. 6. Lower current to 0.6MA. Lower nl04 to 0.6e20. Repeat step 2 and determine whether there is a power level that gives a good pedestal collisionality match to the EDA H-modes in steps 3,5. 7. Repeat step 3 with an appropriately chosen level of ICRF.

We accomplished nearly all of the run plan. Early in the run, we developed a discharge which had 3 separate ICRF pulses so that we were able to obtain 3 EDA phases per discharge. We then ran several repeat discharges for the following conditions: Ip=0.8 MA, target ne = 0.8e20/m^3, Prf = 2.0 MW (shots 11-14) Ip=0.8 MA, Prf = 2.5 MW (shots 15-17) Ip=1.0 MA, target ne = 1.0e20/m^3, Prf 2.5 MW (shots 24 - 26) Ip=1.0 MA, Prf = 2.7 MW (shots 27 - 28) Ip=0.65 MA, target ne = 0.65e20/m^3, Prf = 2.5 MW (shots 29-31, 33) Shots 31 and 33 had higher Prf in the 3rd EDA phase. Much good data were collected from a number of diagnostics, including TS, ECE, PCI, reflectometers, GPI. The natural variability of the timing of the L-H transition provided sufficient time history coverage for the build-up of the edge pedestal, as measured with the TS system. Therefore, we did not vary diagnostic timing in any controlled way. Control room analysis by Jerry shows that we obtained adequate coverage of the pedestal evolution from the L-H transition to the turn-on of the EDA. We should also have good data for the EDA turn-off, but we did not have much time to examine that in the control room. The general picture that we formed in the control room was that the pedestal electron pressure gradient stopped increasing at about the time that the QCM turned on and that the QCM turned off about the time that pressure gradient started to drop. This was consistent at all current and power levels. Clearly, though, this preliminary conclusion needs to be checked much more carefully in subsequent analysis.

Dec 10 2009 11:27:26:337AM	1091210011	Richard Groebner	Goal: Run multiple RF pulses to make several periods of EDA Result: This worked. Obtained 3 clear phases of EDA. Plasma stays in EDA for a while after RF turns off. Plasma did not make clear return to L-mode between 3rd and 4th RF pulses. First EDA: Pedestal pegrad reaches max at about 0.65 s and then drops some. QCM turns on at about 0.62 s.
Dec 10 2009 11:38:20:120AM	1091210012	Richard Groebner	Goal: Lengthen RF on and off times to try to get to more of a steady state in EDA. Result: This worked. 2nd EDA is nicer than the first. For 2nd EDA phase, pedestal gradpe saturates about 0.97 s. QCM turns on 0.97 - 0.975 s
Dec 10 2009 11:55:01:057AM	1091210013	Richard Groebner	Goal: Repeat Result: Obtained one EDA pulse with RF on
Dec 10 2009 12:11:37:773PM	1091210014	Richard Groebner	Goal: Repeat, except for moving outer strike point down Result: No significant change from previous shot. Good EDA during 2nd RF pulse. Pedestal gradpe saturates somewhere between 1.05-1.08 s QCM returns on about 1.1 s
Dec 10 2009 12:26:07:493PM	1091210015	Richard Groebner	Goal: Raise max power to 2.5 MW Result: Good shot. Obtained 3 EDA phases. 2nd EDA: pedestal gradpe saturates about 0.97 s; QCM turns on about 0.97 s
Dec 10 2009 02:32:42:320PM	1091210016	Richard Groebner	Goal: Repeat Result: Good shot, 3 EDA pulses 1st EDA phase: pedestal gradpe saturates ~ 0.64 s; QCM turns on about 0.59 s End of 1st EDA phase: pedestal gradpe starts to drop ~ 0.71 s; QCM frequensy starts to rise about 0.70 s and turns off about 0.73 s. 2nd EDA phase: pedestal gradpe saturates ~ 0.99 s; QCM turns on about 0.96 s 3rd EDA phase: pedestal gradpe saturates ~ 1.44-1.47 s; QCM turns on ~ 1.39 s
Dec 10 2009 12:41:16:120PM	1091210017	Richard Groebner	Goal: Repeat Result: Good shot, 3 EDA pulses
Dec 10 2009 12:54:32:180PM	1091210018	Richard Groebner	Goal: Increase Ip to 1.0 MA; increase target density to 1.0e20 Result: no plasma
Dec 10 2009 02:19:29:243PM	1091210019	Richard Groebner	Goal: Obtain 1.0 MA shot Result: Obtained 3 EDA phases, last phase stays in EDA during Ip ramp down
Dec 10 2009 02:15:04:883PM	1091210021	Richard Groebner	Goal: Repeat 1.0 MA shot Result: Good shot, missing Thomson and perhaps other data
Dec 10 2009 02:24:09:337PM	1091210021	Jerry Hughes	YAGs didn't fire. No obvious reason why. There are PCI data, however. Contrast this with shot 19, where there was TS, but no PCI.
Dec 10 2009 03:08:49:960PM	1091210023	Richard Groebner	Goal: Repeat 1.0 MA shot Result: Good shot. No TS data.
Dec 10 2009 05:06:41:743PM	1091210024	Richard Groebner	Goal: Repeat 1.0 MA shot Result: Good shot. Have 3 EDA phases, first one does not achieve quite the pressure of the 2nd two pulses. Looks like we have all data.
Dec 10 2009 05:06:58:507PM	1091210026	Richard Groebner	Goal: Repeat 1.0 MA shot, increase prf to 2.7 MW Result: Good shot - has 3 EDA phases, possible MARFE early. More power has pushed us in the desired direction - first EDA phase looks more like the other two.
Dec 10 2009 05:07:22:680PM	1091210026	Richard Groebner	Goal: Repeat 1.0 MA shot, increase prf to 2.7 MW Result: Good shot - has 3 EDA phases, possible MARFE early. More power has pushed us in the desired direction - first EDA phase looks more like the other two. 2nd EDA phase: pedestal gradpe saturates ~ 0.99 s; QCM turns on at about 0.99-1.01 s? A bit difficult to determine exactly when.
Dec 10 2009 04:58:50:650PM	1091210027	Richard Groebner	Goal: Repeat 1.0 MA Result: Good shot, 3 EDA phases
Dec 10 2009 04:58:41:243PM	1091210028	Richard Groebner	Goal: Repeat 1.0 MA Result: Good shot, 3 EDA phases 1st EDA phase: pedestal gradpe is saturated from ~ 0.61-0.69 s; QCM on from about 0.60-0.72 s
Dec 10 2009 04:58:28:150PM	1091210029	Richard Groebner	Goal: Reduce Ip to 0.65 MA, target density to 0.65e19, Prf to 2.5 MW Result: Good shot, had 3 EDA phases, had an injection which ended first EDA phase 2nd EDA phase: pedestal gradpe 0.96-1.11 s, QCM on from 0.96-1.12 s
Dec 10 2009 04:58:16:710PM	1091210030	Richard Groebner	Goal: Repeat Ip 0.65 MA Result: Good shot, had 3 EDA phases
Dec 10 2009 04:58:06:430PM	1091210031	Richard Groebner	Goal: Repeat Ip 0.65 MA, Increase power in 3 RF pulse Result: Good shot, have 3 EDA phases again. More RF power - some faulting on J-port 3rd EDA phase: pedestal gradpe saturated from ~ 1.34-1.49; EDA on from ~ 1.37-1.52 s - it starts weak and at high frequency and then spins down
Dec 10 2009 05:06:14:460PM	1091210032	Richard Groebner	Goal: Repeat Ip 0.65 MA, Reduce power request in 3rd RF pulse Result: Early disruption
Dec 10 2009 05:57:12:960PM	1091210033	Richard Groebner	Goal: Repeat Ip=0.65 MA Result: Good shot, had 3 EDA phases, 3rd phase had good high power ICRF
