| Run Summary for 1031118, MP#335: "Edge plasma flows in upper versus lower x-point discharges" Physics Operator: W. Rowan Session Leader: B. LaBombard ________________________________________________________________________________ 1031118 Run Plan Purpose: The primary purpose of these experiments is to investigate the sensitivity of the magnitude and direction of the parallel plasma flows (routinely observed in the edge plasma) to the magnetic geometry, in particular upper, lower and double-null configurations. Today's Run: This run is a continuation from 1031114. Today we are looking to finish the comparisons between single-null upper and lower and then move on to double-null discharges. We also want to revisit some NL04 = 0.6 and 0.7 discharges since John saw no change in the core argon rotation on Friday going from upper to lower null while the probes still saw large flows in the inner wall. For all shots, we want left gap to be 13 mm and right gap to be 15 mm This will allow the ISP to reach the separatrix and provide a reasonable SOL width at the outer midplane to look at flows. NINJA gas setup is 400 torr helium (8 PSI). All shots are nominally 0.8 MA, 5.3 tesla discharges Optional RF conditioning after 1.2 s Reload from shot#1031114027 with segment 3 turned on Set density program (in segment 3!) to NL04 = 0.6 NOTE on shot#1031114027: Segment 2 - single null lower Segment 3 - single null upper Segment 4 - double null Shot Plan: Single Null Upper (SNU) 1,2 - NL04 = 0.6,0.7 SNU Switch to SNL 3,4 - NL04 = 0.6,0.7 SNL 5,6 - NL04 = 1.2, SNL Switch back to SNU 7,8 - NL04 = 1.2, SNU Begin density scan in DN configuration. Shot#9,10 (DN) Turn on segment 4 Program NL04 = 0.8x10^20 m^-2 Can proportional gain on SSEP be decreased to remove x-pt oscillations? Increase right gap by 3 mm (to 15 mm). Decrease left gap by 3 mm (to 13 mm). Check probe targeting. 11,12 - NL04 = 0.6, DN 13,14 - NL04 = 1.0, DN 15,16 - NL04 = 1.2, DN ________________________________________________________________________________ Result: We got 10 data-quality shots today for a full run-day spent. (Computer related problems soaked up most of the run time.) The SNU/SNL density scan is now complete. The double-null density scan remains to be done. One would think this could be accomplished by scheduling another half day.... Strong parallel flows were again detected by the probes, similar to the overall behavior seen in recent days. The new data should provide us with good profile data from all three probes (ASP,FSP,ISP) up to the separatrix. A big surprise was the change in the behavior of core rotation seen today compared to that seen last friday. On friday, John saw the rotation clearly depend on SNU/SNL x-point location (more counter-rotation in SNU) for all densities except the NL04 = 0.6 data points. Today, the rotation was strong counter-rotation, independent of SNU/SNL and density! So either the measurement is suspect or the core rotation cares about some other unidentified parameter. It will be interesting to see if corresponding differences are present in the Mach probe data. Shot Summary: [values in () are probe rest positions for future reference] 1,2 - cycle tests 3,4,5 - no power shots 6 - SNU, NL04 = 0.54 and rising - ASP(+8.5), FSP(+8.5), ISP - good data 7 - SNU, NL04 = 0.6 and rising to 0.8 - ASP(+8.5), FSP(+8.5), ISP - good data 8 - SNU, NL04 = 1.2 -> 1.4 - ASP(+8.5), FSP(+8.5), ISP - could be deeper 9 - SNU, NL04 = 1.2 -> 1.4 - ASP(+9.5), FSP(+9.5), ISP - could be deeper ISP shows very little density - looks like detachment 10 - dud 11 - SNU, NL04 = 1.05 -> 1.2 - ASP(+10), FSP(+11), ISP 12 - fizzle 13 - SNU, NL04 = 0.9 -> 1.0 - ASP(+9), FSP(+11), ISP 14 - disrupted early ....... long computer-problem delay..... 15 - SNL, NL04 = 1.1 -> 1.4 - ASP(+8.5), FSP(-4), ISP - good data 16 - SNL, NL04 = 1.15 -> 1.33 - ASP(+8.5), FSP(-4), ISP - good data 17 - SNL, NL04 = 0.6 -> 0.7 - ASP(+8.5), FSP(-4), ISP - good data 18 - SNL, NL04 = 0.67 -> 0.75 - ASP(+9), FSP(-4), ISP - excellent data 19 - Early disruption |

| Run Plan for 11/18/03 Purpose: MP #335-Edge plasma flows in upper vs lower x-point discharges Session Leader: LaBombard If MP335 completed, go on to Purpose: MP #363 LH Threshold Session Leader: Hubbard Physics operator: Rowan Engineering operators: Cochran, Fitzgerald, Parkin ----------------------------------------------------------------------------- Summary This was a continuation of run 1031114. Starting from shot 1031114027, we completed density scans in SNU and SNL configurations. There was one dud during this run which was due to a power systems problem. There were two disruptions at early times (approximately 0.15 s). Shots before and after the two disruptions were okay. It is not clear from the data what caused the disruptions. Possibly something fell in. After shot 014, there was a problem with the RAID. This was corrected, but required more than three hours and time lost there accounted for the small number of shots on an otherwise quite successful day. The absence of fizzles -- a hallmark of last week's runs -- was encouraging. We did not complete the double null part of MP 335 and did not start on MP 363. ----------------------------------------------------------------------------- Score card Useful Plasmas 16 Early disruptions 2 Fizzles 0 Duds 1 (due to power systems) Total 19 ----------------------------------------------------------------------------- Log Engineering Setup and Run Plan for 11/18/03 Purpose: MP #335-Edge plasma flows in upper vs lower x-point discharges Session Leader: LaBombard If MP335 completed, go on to Purpose: MP #363 LH Threshold Session Leader: Hubbard Physics operator: Rowan ECDC overnight in D2 at 2e-4 Torr, stopping by 07:00.

Start from shots on in Brian's MP (11/14 and 11/18 am). Adjust shape as indicated by Jerry; cell access to adjust fibre positions if needed. This will determine kappa and delta for the other configurations. 2) Switch to LSN. 800 kA, ~ 5.4 T. 3-4 shots. a) Power ramp up to ~ 3 MW, to determine L-H threshold. b) Discharge with fixed power just below threshold, for 100-200 ms, followed by high power phase (4-5 MW). Repeat as needed for probe, HIREX. 3) Switch to DN . 5-6 discharges. a) 2 Discharges at power which gave L-H threshold in LSN (eg. 1 MW). Document ETS profiles, flows, rotation. b) Power ramp to maximum available (5 MW>) to determine the new L-H threshold. c) As above, make discharges with power just below L-H transition for ~ 200 ms, followed by higher power to get H-mode phase. 001.
