Run Plan for 1070602, pm session MP#489 "Damping rate of TAEs near stability threshold with ICRF fast ions" Goal **** Observe the stability of moderate n (~6-14) TAEs relative to the ICRF generated ion tail temperature as the ICRF power is successively increased. This experiment was preliminarily investigated on 1060526 under MP#404a, and will be resumed now with an improved set of magnetic field probes. Run Preparation *************** * Prepare argon for HIREX * Setup GPC2 gratings for 5.8~6.0 T * Enable the dpcs_ftae2 procedure in DPCS (see Wolfe email of 1070601) * Turn on Active MHD and set qAE to 1.5, AE_order to 2 * Allow boron dust puffing Run Plan ******** Reload equilibrium from 1060526032 but with negative field and current. Shot Plan ********* Begin by reproducing results from 1060526; look for stable TAEs throughout RF heating phase. Then increase Bt to move ICRF off axis but maintain sufficient heating (watch ECE temp and neutron rate, CNPA if available). Run Picrf=2MW during 0.75-1.5s 001 Field = -5.4T, Ip=-0.8MA, NL04=0.7e20 002 Set field to -5.7T, Ip=-0.6MA, NL04=0.7e20 003 -5.9T 004 -6.1T At highest field that maintains sufficient heating, step RF power by 0.5MW every shot up to max available power. As time allows, repeat highest power shot, then decrease by 0.5MW every shot to repeat conditions. Run RF during 0.75-1.5s at the following powers: 005 0MW 006 0.5MW 007 1.0MW 008 1.5MW 009 2.0MW 010 2.5MW 011 3.0MW? 012 3.0MW 013 2.5MW

SL Plan: Goal: Verify J dipole configuration and investigate range of operation for given neutral pressure. Plan: Use near "standard" LSN (1070510007) and near double null (1070601023) H-mode discharges to 1. Test power handling of J dipole configuration 2. scan plasma density -> establish density range start at nl_04~0.7->1.4 or neutral limit 3. scan plasma current - does it effect neutral limit 4. if time available, test operation in presence of cryopump 5. if time available, neutral pressure limits with He plasmas

Dipole configuration works over much broader pressure range in comparison to 4-strap configuration. The J dipole, ~0.65 mTorr, is not quite as good as D and E, ~1 mTorr, at 0.8 MA. Would like to investigate this limit further by having a larger current and density scan.

The run started out trying to reproduce results from 1060526032. The first three shots had bad tuning in the Active MHD amplifiers due to the old DPCS module, but that was quickly sorted out. There was trouble tuning J antenna so we only got up to 2MW, a good deal lower than the 3.5MW achieved on 1060526. But there were quite a few clear resonances observed, and the heating was successfully moved off axis. We stayed at -5.9T to make tuning J easier, but even -6.1T seemed to allow good heating efficiency. Shot summary 014: Attempt to duplicate 1060526032. Used old module. 015: Same. 016: Attempt at 5.7T. Still old module. 017: New DPCS_ftae2 module loaded. -5.7T, -0.6MA, 0.7e20, 1.7MW. Several clear resonances 018: -5.9T, 2.1MW 019: -6.1T, 1MW 020: -5.9T, 2MW 021: -5.9T, 2MW 022: -5.9T, 1MW 023: -5.9T, 1.2MW 024: -5.9T, 1.4MW 025: -5.9T, 0MW, disrupt at 1.1s

We started out with a data system problem that required Mark and Henry to reboot all the data servers. Shot 01 was then a no power shot to check that everything was okay. Shot 02 was the first plasma shot, the rf fiducial LSN, 1 MA, 9e19/^2. On shot 08 and 12 today the TF current exceeded the request by 2 and 5 kA respectively. The run was delayed by about an hour to investigate. It appeared to be the AFOL link between the DPCS and the TF control cabinet. There is a 0.2 V offset that needs to be fixed. After going in and looking at the AFOL the following shot was fine (13) We made the switch from mp355 to 485 on shot 14. I forgot to reload dpcs_ftea2 and caused the MHD antenna to misbehave for a couple of shots. This error was corrected on shot 17. The machine ran extremely well today, with 100% startup. The only problem was on shot 24 which disrupted at 1.06 s with an injection score: tests 01 plasmas 02,03,04,05,06,07,08,09,10,11 12,14,15,16,17,18,19,20,21,22 23,24,25 no duds, no fizzles

Jun 5 2007 02:54:31:840PM	1070605015	Jason Sears	Moving onto physics shots since the day is late. Field was left at 5.4 by accident. Bt: -5.4T Ip: -0.8MA Nl04: 0.9e20 Picrf: 2
Jun 5 2007 03:04:19:997PM	1070605016	Jason Sears	Attempted only D and J antennas to avoid 500kHz interference. Shots 14-16 have had horrible antenna current. Bt: -5.7T Ip: -0.6MA Nl04: 0.7e20 Picrf: 0.8MW
Jun 5 2007 03:23:44:450PM	1070605017	Jason Sears	Figured out that loading the new model shot also changed the DPCS module to the outdated one, which does not provide the correct tuning signal. The problem has been fixed for this shot, and we'll repeat the first physics shot of -5.7T. Bt: -5.7T Ip: -0.6MA Nl04: 0.7e20 Picrf: 01.7MW
Jun 5 2007 03:24:09:700PM	1070605017	Jason Sears	Several clear resonances found during RF.
Jun 5 2007 03:30:41:950PM	1070605018	Jason Sears	Increased field to -5.9T. Heating still appears to be effective by Te0 and neutron rate. One ok resonance found during RF. Bt: -5.9T Ip: -0.6MA Nl04: 0.7e20 Picrf: 2.1MW
Jun 5 2007 03:49:45:387PM	1070605019	Jason Sears	Increased field to -6.1T. Heating still appears to be effective by Te0 and neutron rate but achieving high RF power is hard at that field. Bt: -6.1T Ip: -0.6MA Nl04: 0.7e20 Picrf: 1MW
Jun 5 2007 04:33:37:730PM	1070605020	Jason Sears	Began RF power scan with D,E and J antennas, aiming for 3MW at -5.9T. J matching wasn't great, so got only 2MW. Bt: -5.9T Ip: -0.6MA Nl04: 0.7e20 Picrf: 2MW
Jun 5 2007 04:44:20:183PM	1070605021	Jason Sears	Still got only Picrf: 2MW
Jun 5 2007 04:43:05:027PM	1070605022	Jason Sears	Good resonances found during RF. Picrf: 1MW
Jun 5 2007 04:44:50:620PM	1070605022	Jason Sears	Try a lower power shot and work on tuning J antenna.
Jun 5 2007 04:42:06:560PM	1070605023	Jason Sears	Attempt at 2.4MW with J antenna. Got only 1.3. Bt: -5.9T Ip: -0.6MA Nl04: 0.7e20 Picrf: 2MW
Jun 5 2007 04:42:32:153PM	1070605024	Jason Sears	Settle for a 1.5MW shot.
