Run Summary for 1000829 MP 253 Very Low Power EDA Session Leader - M. Greenwald Phys Op - E. Marmar With its good energy confinement, moderate particle confinement and lack of large ELMs, the EDA H-mode could be a highly favorable regime for a tokamak reactor - if we can understand the underlying physics sufficiently to extrapolate into new regimes. The key to understanding EDA seems to be in the quasi-coherent fluctuations which have been observered by the reflectometer, PCI, and probes. These fluctuations seem always to accompany EDA and have been shown to drive significant particle flux. We want to understand the relationship between the mode and the local pedestal profiles allowing us to evaluate the micro and macro-stability. The first step will be to localize the mode relative to the density and temperature pedestals. We will try to correlate both mode amplitude and convected flux with the local gradients. Because the range of the scanning probe is limited by incident heat flux, we will attempt to run EDA H-modes at the lowest possible powers. Following the recipe that was successful on 990831, we will begin with discharges at relatively low q and then scan Bt and Ip to raise q allowing access to the EDA regime. Since q(t) must be similar from shot to shot, lowering the power will necessarily mean running at both lower field and current. Possible scenarios are shown in the figure attached to the MP. Our main goal is to look for magnetic components of the quasi-coherent mode with the A side scanning probe (with its magnetic pickup). We are also getting our first look at an EDA with the fast framing tangential camera. This is set up with an Halpha filter and a hydrogen puff. ============================== Results: A good day. Especially for the first day after boronization. Ohmic H-modes were easy to get. The EDAs were not as clear as in some previous runs, but the Q-C fluctuations were clearly seen on the reflectometer, electrostatic probes AND on the magnetic probes. These were seen clearly when the probe was within 1-2 cm of the separatrix. The e-folding distance of the magnetic signal was consistent with the probe size, so won't tell us anything about the m number. Although the probe itself never got closer than 1 cm of the separatrix, the amplitude of the signal reached 400 T/sec peak to peak. Accounting for the mode frequency, this corresponds to about 4 G or about 20 A/cm^2. This is of the same order as the edge current density which is calculated to be approx. 100 A/cm^2. The electrostatic probes, which are part of the same probe head, saw the modes quite clearly - with similar time histories, etc. The main distinction is that they only see the mode when they are immersed in it (deep penetration) but the magnetic probe provides signals when it is only close. The conclusion is that the Q-C mode has a very significant magnetic component. On shot 21, the probe caught some ELM precursors (presumably from type III ELMs. These were also seen with the wall magnetics suggesting that they lower m number. These fluctuations were not seen on the floating potential, strengthening this conclusion. Thus we would conclude that the Q-C mode is distinct from ELM precursors. On shot 29, the probe was inserted to with 8 mm of the separatrix and left to dwell there for the entire shot. A time history of the magnetic fluctuations was obtained. This had a time history which was essentially identical to the reflectometer. We got images with the fast camera for most shots. Clear differences between L-mode, ELMfree H-mode, and EDA are seen. Light from L-modes are quite broad, extending 5-6 cm outside the separatrix. In ELMfree H-mode, the region of emission is much narrower and hugs the separatrix. During EDA, clear fluctuations are seen outside the separatrix. These are: 1. not terribly coherent 2. not where the electrostatic probe has seen fluctuations 3. too large. So while these suggest additional transport in the far scrape-off (consistent with profile measurements) they do not seem to be the Q-C fluctuation itself. ================================ Shots suitable for further analysis include: 1000829014 Multiple H-modes, Weak eda during first two hmodes seen with reflectometer and magnetic probe amplitude about 400 T/sec peak to peak at 140 kHz,corresponds to about 4 G this corresponds to about 20 Amps/cm^2 1000829015 Single h-mode only much weaker eda 1000829017 One H-mode period fluctuations seen on probes (before peak insertion)and reflectometer 1000829018 Single longer H-mode weak EDA good fluctuations seen of reflectometer 1000829018 Single longer H-mode, weak EDA with clear transition at 0.82 sec good fluctuations seen of reflectometer Clear differences seen between ELMfree phase and EDA slight effects on Halpha 1000829019 Probe catches EF/EDA transition in the middle of the first scan clear potential and B field fluctuations seen 1000829019 Probe catches EDA/EF transition in the middle of the first scan clear potential and B field fluctuations seen 1000829020 Similar to previous shot, 2nd h-mode makes transition to EDA caught by second probe scan 1000829021 2nd probe plunge sees elm precursors and elms (type III?) just before the H/L transition at 1 sec these are not seen on floating potential but are seen on fixed magnetics. Suggests that this mode is not the same as the quasi-coherent mode. 1000829020 Interesting frames on fast camera, look at 53-60 shows EF to EDA to L-mode transitions 1000829023 First probe scan in EF, 2nd into EDA clear difference in fluctuation character seen 1000829024 Similar to previous shot clear dithering seen on B probe correlates with H alpha 1000829025 Probe in maybe a bit too far some impurities injected 1000829026 Similar to shot 25 1000829027 Higher density Similar H-mode EDA is weaker 1000829028 Lower density, stronger eda 1000829029 Probe in dwell mode got good time history of magnetic fluctuations

Run Plan and Engineering Setup for 1000829 Boronization recovery MP253 Low power EDA H-modes Physics Operator: Marmar Session Leader: Greenwald Engineering Operators: Cochrane/Dekow/Parkin Engineering Setup: Following boronization, He ECDC stopping 1 hour before the run commences Power systems setup: Same as for 1000825001 Set OH1, OH2U and OH2L fizzle delays at 300ms Set TF fizzle delay at 400 ms Gas setup: B-Top 6 psi D2 Hybrid Enabled B-side lower 1 psi Argon Hybrid Enabled B-side upper ~30 psi He Hybrid DISABLED (reserve for between shot ECDC) C-side 30 psi D2 Hybrid Enabled J-bottom leave as is Hybrid DISABLED The following Gate Valves should be ENABLED, assuming no vacuum problems: ECE, VUV Run Plan: Recover normal operation following boronization. If fizzles are a big problem, we will consider between shot ECDC in helium. If recovery goes well, turn the run over to MP253 Low power EDA, with Greenwald as session leader. At some point during the day, we will run an EF4-only test for magnetics check-out. Results: Date: 29-AUG-2000 09:00 Expires: 12-SEP-2000 00:00 From: DAIGLE::IRBY Subj: Boronization We boronized the machine last night. Approx. 140 psi of diborane gas was used corresponding to about 2048 Angstroms of boron on the walls. The boronization was followed by 2.5 hours of ECDC in helium at 5.e-5 Torr. The run went well. Recovery from boronization was achieved by shot 6, and the run was turned over to MP253 starting on shot 7. After that we had almost all good plasmas, many of which were useful for the mini-proposal. Shot 1 ran through (loaded from last week). After that, we needed to raise the fill pressure, perhaps partly because the sparker draws very little current right after boronization, and partly because the fill pressure was on the low side anyway. Shot 22 disrupted early because of a power supply problem (OH2L). Shot 31 went to 68 kA, and then died, going down. Shot 32 was the EF4 test.

Aug 29 2000 09:56:03:123AM		Martin Greenwald	MP 253 Very Low Power EDA (After boronization re-start) Session Leader - M. Greenwald Phys Op - E. Marmar Background: With its good energy confinement, moderate particle confinement and lack of large ELMs, the EDA H-mode could be a highly favorable regime for a tokamak reactor - if we can understand the underlying physics sufficiently to extrapolate into new regimes. The key to understanding EDA seems to be in the quasi-coherent fluctuations which have been observered by the reflectometer, PCI, and probes.

The principle goal for the day will be looking for a magnetic component to the quasi-coherent oscillation which has been previously observed with the reflectometer, pci, and langmuir probes. We will also be looking for a visible image of the fluctuation using the fast edge framing camera.
