Engineering setup for Tuesday 2010/02/23 MP591 - Boundary layer heat transport experiments in H-mode plasmas Session leaders: B. LaBombard Physics operator: R. Granetz Overnight: standard boronization followed by 2 hours of ECDC in helium and and then 1 hour of ECDC in D2, along with a 60 C bake Run will start at 09:00 and end at 17:00. Power systems as on 1100212032 (LSN, 0.8 MA, 5.4 T) A-coil configuration: +Dtop -Dbot -Jtop +Jbot; Enabled (standard configuration) Gas Setup: fill B-Top with 6 psi D2 Hybrid enabled (PG4) fill B-side lower with 2 psi Ar Hybrid DISABLED (PG1) leave B-side upper as is Hybrid DISABLED (PG2) fill B-main (C-side) with 40 psi D2 Hybrid enabled (PG3) leave NINJA as is DISABLED Enable the following gate valves and shutters, assuming no vacuum problems: ECE, VUV, Z-bolo, HIREX-Sr Torvac setup: keep gate valves open during PULSE Specific diagnostics: edge and SOL diagnostics, divertor heat load diagnostics including the IR camera ------------------------------------------------------------------------------ Impurity injector: no Boronization: no between-shot boronization ICRF Setup: up to 4.5 MW with all transmitter systems LH Setup: no DNB: no Cryopump: yes, ready for the start of the run ------------------------------------------------------------------------------ Run plan: start from 1100212032, which was a LSN, 0.8 MA, 5.4 T shot with a ramp programmed into RXL. Set nl_04 target to 0.9e20 m-2. Run a bunch of shots until the RF and the divertor diagnostics recover from the overnight boronization. Then begin filling in the parameter matrix, i.e. vary Psol, nl_04, Ip.

Run summary for Tuesday 2010/02/23 MP591 - Boundary layer heat transport experiments in H-mode plasmas Session leaders: B. LaBombard Physics operator: R. Granetz The tokamak, cryopump, and RF systems worked quite well today. Nearly all shots were full length discharges. We spent the first 10 shots doing post-boronization recovery for the divertor diagnostics and the RF, and then ran a variety of densities and currents in EDA H-modes. For most of the day the startups were not good, with one or two outward bumps on most shots, but I wasn't able to improve it, and it didn't seem to matter anyway. Scorecard: 29 plasmas 0 duds 1 fizzle 0 power supply tests 0 no-power MDS shot cycles -------------- Total: 30 shot cycles

Feb 22 2010 03:49:30:770PM Brian Labombard MP#591 - Boundary layer heat transport experiments in H-mode plasmas

Primary goals for today are:

(1) Set up optimized plasma shape and strike point position for heat flux footprint measurements in 0.8 MA LSN EDA discharges.
Condition RF to 4.5 MW, condition outer divertor for heat flux measurements using strike point sweep.
(2) Having established above, begin filling in the parameter matrix of MP#591 - scan Psol, density,
and plasma current, starting at 0.8 MA

Setup:

Overnight boronization with ECDC cleanup, using parameters identical to evening of 02/11/10.

All shots today will be 5.4 tesla.
NINJA will be used. Set up will be done at run-time by GPI scientists.
ICRF up to 4.5 MW
Cryopump will be used to assist boronization recovery; it may not be needed after the first ~10 shots.

Shot Plan:

Reload from shot#1100212032. This was a 0.8 MA, 5.4 tesla shot with a sweep programmed into RXL.

Feb 23 2010 08:53:40:103AM Robert Granetz

Loaded all segments from 1100212032; set nl_04 to 0.9e20 m-2. Cryopump is ready for shot 01, so set prefill to 52 ms.

Feb 23 2010 09:18:50:133AM 1100223001 Robert Granetz

Shot 01 -- Plasma, full length. 0.8 MA, 5.4 T, nl_04=0.8-0.9e20 m-2, LSN, cryopump. Good RXL ramp. A little RF from J, nothing from D nor E. Next shot: We'll be repeating these shots for awhile in order to clean off the boron from the divertor diagnostics and to condition the RF post-boronization.

Session Leader Comments
Feb 22 2010 03:49:30:770PM		Brian Labombard	MP#591 - Boundary layer heat transport experiments in H-mode plasmas Primary goals for today are: (1) Set up optimized plasma shape and strike point position for heat flux footprint measurements in 0.8 MA LSN EDA discharges. Condition RF to 4.5 MW, condition outer divertor for heat flux measurements using strike point sweep. (2) Having established above, begin filling in the parameter matrix of MP#591 - scan Psol, density, and plasma current, starting at 0.8 MA Setup: Overnight boronization with ECDC cleanup, using parameters identical to evening of 02/11/10. All shots today will be 5.4 tesla. NINJA will be used. Set up will be done at run-time by GPI scientists. ICRF up to 4.5 MW Cryopump will be used to assist boronization recovery; it may not be needed after the first ~10 shots. Shot Plan: Reload from shot#1100212032. This was a 0.8 MA, 5.4 tesla shot with a sweep programmed into RXL. Set L-mode target density to NL04 ~ 0.9e20 at RF turn-on Set ICRF on from 0.7 to 1.5 seconds. Condition RF as needed to 3.0 MW flattop. A. 0.8 MA, conditioning shots, L-mode target NL04~0.9e20 1. Establish steady EDA, PICRF~ 3.0 MW Multiple shots to condition RF to 3.0 MW and sweep strike point over divertor to remove boron layer. Optimize plasma shape, IR camera ~8 shots 2. Program fixed strike point. ~2 shots B. 0.8 MA, RF Power and density Scans 1. NL04~0.9e20, ICRF Power: 2.0, 1.0, then 4.5 MW Alternate between fixed and swept strike point shots. ~8 shots 2. Raise density if possible, respecting neutral pressure limits for ICRF. NL04~1.2e20?, ICRF Power: 1.5, 4.5 MW Alternate between fixed and swept strike point shots. ~4 shots C. 0.5 MA, RF Power and density Scans Change to 0.5 MA. Adjust strike sweep programming as needed. 1. NL04~0.6e20, ICRF Power: 3.0, 1.0, then 4.5 MW Alternate between fixed and swept strike point shots. ~6 shots 2. NL04~0.9e20, ICRF Power: 1.5, 4.5 MW Alternate between fixed and swept strike point shots. ~4 shots ...
