Subject: Further Investigation of Turbulence and Transport in Low Density Ohmic Plasmas to Resolve the Mystery of Electron Transport This run is the second phase of MP 571. The experiments will be carried out at different plasma currents but at the constant toroidal magnetic 5.2 T to allow us to explore the impact of the q profile on electron thermal transport. The experiments start at Bt = 5.2 T and Ip = 0.8 MA to obtain a low-density shot with nebar ~ 0.3 10^20m^-3 in the linear ohmic regime. After this shot is obtained, move to the plasma at Ip = 0.6 and 0.4 MA, while keeping Bt = 5.2 T. At each plasma current, the electron density (nebar) will be scanned from 0.3 (possibly 0.2) to 0.8 10^20m^-3 to cover both the linear ohmic region and the transition from the linear ohmic to the saturated ohmic region. If the time is allowed, we will also try to cover the density scan at Bt = 3.9 T and Ip = 0.6 MA, which is not completed on 1090917.

Subject: Further Investigation of Turbulence and Transport in Low Density Ohmic Plasmas to Resolve the Mystery of Electron Transport A computer problem caused us to lose more than 1 hour today. Moreover, because of locked modes, only single plasma was obtained at 1 MA. However, reasonable coverage in density, current, and magnetic field has been obtained in today's and yesterday's runs.

After 12 hours of ECDC in helium overnight we were able get very low densities today. Shot 01 was around 1e19/m^2 on nl04. However, we also had serious runaway issues that took 5 or 6 shots to fix with probably too small an incremental change in the prefill, the pg3 seg 1 gas puff, and early nl04 programming. Later in the run we also had problems with locked modes, both early and late in the discharge, when trying to get data at 1 MA. The early locked modes were almost certainly the result of a rapid drop in the density before 450 ms. We were eventually able to fill in the early density drop by changing the early nl04 programming. Disruptions caused by the locked modes resulted in a few fizzles today since it was hard to lower the prefill, as we usually do following disruptions, without getting back the runaways. We had to enter the cell to zap one of the full flux loops. We somehow managed to fill up the data disks and lose data on shot 24. Much work by Josh to restore some of the data. Had one no power shot (25) because of a CAMAC server issue. On shot 30 the EF2 power supply stopped following demand. This problem will have to be fixed on Monday. no power 025 fizzle 09,10,18 plasma 01,02,03,04,05,06,07,08,11,12,13,14,15 16,17,21,22,23,24,26,27,28,29,30 disruption 01,08,16,17,30

Session Leader Comments
Sep 18 2009 08:57:15:800AM	1090918001	Liang Lin	Shot 1: Lots of runaways. Next: Repeat.
Sep 18 2009 09:31:36:783AM	1090918002	Liang Lin	Shot 2: Still a lot runaways. The plasma is in the linear ohmic regime for sure. However, no reliable density and temperature profiles from TS or ECE. Consequently, the data is not usable. Next: raise nl04 to 0.15 10^20 m^-2 to see the situation improves.
Sep 18 2009 09:27:14:610AM	1090918003	Liang Lin	Shot 3: Still a lot runaways. Next Shot: raise nl04 to 0.2 10^20 m^-2.
