MP#570 - Boundary layer heat transport experiments in L-mode plasmas Goal 8 tesla discharges today We will target the 8 tesla data sets as outlined in the MP, performing density scans at 0.8 MA and 1.2 MA. Setup Reload shot#1100803007, with request for NL04 ~ 0.3. This shot had the desired strike point sweep on the outer divertor, with all gaps tuned up nicely, including a ramp of the outer gap for the ASP. We will adjust gap programming as needed. Program toroidal field to 8 tesla. NINJA should be filled to 10 PSI He for GPI. Program gas to hit plasma at 1.2 s. IR camera on and aligned. Set ASP, FSP and WASP scanning probes to fire at 0.8, 1.0 and 1.2 seconds Argon will be enabled for HIREX data at the same puff parameters as on 1100721. Cryopump with be used from the start. Helium ECDC for 1 hr prior to run. No ICRF or LHRF. A. LSN, 8 tesla, 0.8 MA NL04~ 0.4, 0.55, 0.7, 0.85,1.0e20 Two shots at each density, probes scanning to resolve shear layer. B. LSN, 8 tesla, 1.2 MA NL04~ 0.6, 0.8, 1.0, 1.2, 1.4e20 Two shots at each density, probes scanning to resolve shear layer. |

Run plan: This will be an 8 tesla run, so I've loaded seg 1 from seg 1 of
1100319018 (the most recent 7.8 T shot). Changes: increase
TF_current to 224 kA to get 8.0 T; set pre-fill pulse to 55 ms
(cryopump startup).
Load seg 2 from seg 2 of 1100803007.
Changes: load TF_current waveform from seg 2 of 1100319018, then
increase to 224 kA; start Ip rampdown at t=1.3 s (which is
consistent with the TF programmed rampdown starting at 1.25 s)
Alternator RPM will have to be increased to ~1715.
PLC limits on TF will have to be increase to allow 224 kA

| Run Summary for 1100811
MP#570 -- "Boundary layer heat transport experiments in L-mode plasmas" It was a successful run day for MP#570. We managed to complete two density scans at 7.9 tesla toroidal field, one at 0.8 MA and one at 1.2 MA. Although we did not obtain the top-end densities that were called out in the run plan (target values: 1.0e20 @ 0.8 MA and 1.4e20 @ 1.2 MA), we got close enough to see the roll-over of the divertor conditions to a high-recycling regime where the divertor heatflux footprint begins to be affected (achieved values: 0.94e20 @ 0.8 MA and 1.2e20 @ 1.2 MA). The IR camera was operated on most shots, but Jim Terry reported numerous cases where the camera dropped large blocks of frames (unrecoverable) or the software had trouble with saturated frames or stabilization problems (recoverable?). Apparently, the large toroidal field (~8 tesla) caused the periscope to swing with higher amplitude than usual, testing the limits of the stabilization algorithm. Gas-puff imaging (diodes and phantom camera) was routinely performed with good data being reported. We ran all shots with the strike-point programmed sweep up the divertor plate such that the embedded probes could sample the footprints with high resolution. The run got off to a slow start, with two test shots dedicated to getting a pulsed-gas value conditioned plus a delay while blockage to an LN2 feed line for the cryopump could be resolved. Shot# 5 was the first 8 tesla shot, which ended in a TF crowbar and some blown fuses. Reducing the TF pulse length to limit temperature rises in the power supply fixed the problem. We cranked out a perfect string of 8 tesla shots after that time, with the exception of shot#8 which was a locked-mode reference shot (5.4 tesla) for Matt Reinke. Shots 5 through 13 (except 8) were performed at 0.8 MA with increasing density. ASP, FSP and WASP scanning probes were successfully operated to map out the 'upstream' conditions in detail. We carefully monitored the heat flux profiles on the outer divertor as reported from embedded Langmuir probes and surface thermocouple sensors. In the sheath-limited regime, the profiles reported by these two separate measures agreed. An e-folding length of 2.8 mm in the common zone was a typical value. As the divertor transitioned into the high recycling regime (NL04 ~ 0.8), two things happened: (1) heat flux profiles from the LPs and TCs started to disagree, with the LPs reporting higher heat fluxes that the TCs, and (2) e-folding lengths by both measures got longer. It is clear from the thermal sensor data (surface TCs, tile TCs, calorimeters) that the LP data is not to be trusted for heat flux analysis in this regime; the LP-inferred heat flux simply does not arrive on the plate. We saw this same behavior play out previously in 5.4 tesla shots at 0.55, 0.8 and 1.04 MA at a similar densities normalized to the Greenwald density, so it is a very robust result. Shots 14 through 20 were done a 1.2 MA. Running out of wall clock time, we had to rush through the density scan, taking only one shot instead of the usual 2 at each density point, with an elevated anxiety level about the fate of the scanning probes. Fortunately, the scanning probe targeting was adequately maintained, if not optimal -- at least we didn't toast anything. A similar behavior was found with regard to the divertor footprints recorded by the surface TCs and the Langmuir probes, but now with the power e-folding length in the common zone being ~ 2.2 mm at the 1.2 MA conditions. Phys-Op Bob Granetz (with Greg Wallace as assistant) did an excellent job today. Many thanks to the entire operations staff for running the final shot after 5:00 pm -- a bad habit that this session leader will have to break. Having more or less completed the 8 tesla data set, our plan is to let MP#570 lie fallow for a while to digest the results and to focus our attention back on EDA H-modes again (MP#591).

MP570 - Boundary layer heat transport experiments in L-mode plasmas
Session leader: B. LaBombard
Physics operator: R. Granetz
This run was all at 8 tesla (except the first plasma shot, 1100811003,
which was done at 6 T to make sure all the TF instrumentation was working
properly). This required reloading the startup and PLC settings from the
most recent high-field run last March. We ran two different plasma
currents, 0.8 MA and 1.2 MA, and a range of densities at each current. The
tokamak ran very well at 8 T and both currents. The only problem was on
shot 5, the first 8 T shot, on which some of the TF SCR's tripped their
overtemperature limit, resulting in a TF crowbar and two blown fuses. I
worked around that problem by shortening the TF pulse by 200 ms, by
starting the TF later. Everything went like clockwork after that. In
order to keep the magnet temperature from rising much, we stayed in RECOOL
for 20 minutes to begin with, but eventually had to extend that by a few
extra minutes.

Shot 01 -- No-power cycle and gas test. Got the pre-fill, but nothing from the main fueling valve.
The F-side ratiomatic pressure gauge is working again.
Next shot: try another no-power gas test shot to unstick the valve
|
| Aug 11 2010 09:40:59:297AM | 1100811002 | Robert Granetz |
Shot 02 -- No-power gas valve test. This time the B-main valve actually opened.
Next shot: Go for plasma, but at Jim Irby's suggestion, I have reduced Btor to 6 T for
this first plasma shot, just to check that all TF diagnostics are working.
|
| Aug 11 2010 09:39:23:617AM | 1100811003 | Robert Granetz |
Shot 03 -- Plasma, full length. 0.8 MA, 6.0 T, 0.4e20 m-2, LSN, cryopump.
The TF rampdown starts at t=1.25 s, as programmed, and the Ip
rampdown starts at t=1.30 s, as programmed.
TF instrumentation is all working properly.
Next shot: go for 8 tesla plasma
|
| Aug 11 2010 09:56:44:200AM | 1100811004 | Robert Granetz | Shot 04 -- No-power shot cycle because the cryopump was not ready. Cell access to check on cryopump LN2 line Next shot: 8 T plasma; I've tweaked RCUR programming to adjust outer gap, at the SL's request. |
| Aug 11 2010 10:56:29:157AM | 1100811005 | Robert Granetz |
Shot 05 -- Plasma, full length. TF crowbarred due to SCR overtemperature. TF gets to flattop
around t=0.4 s. 0.8 MA, 7.9 T, 0.4-0.5e20 m-2, LSN, cryopump. Outer gap evolution
is not quite what JT wants.
Long delay to change TF fuses.
Next shot: start TF 200 ms later (PLC set to -1.3 s instead of -1.5 s) to shorten TF flattop
at the beginning end; tweak RCUR programming some more
|
| Aug 11 2010 11:17:40:167AM | 1100811006 | Robert Granetz |
Shot 06 -- Plasma, full length. No TF overtemps. 0.8 MA, 7.9 T, 0.4-0.5e20 m-2, LSN, cryopump. Outer
gap evolution is improving.
Next shot: a bit more tweaking of RCUR to tailor the outer gap scan around end-of-flattop;
add -0.3 mT to BR_0
|
| Aug 11 2010 11:29:44:500AM | 1100811007 | Robert Granetz |
Shot 07 -- Plasma, full length. 0.8 MA, 7.9 T, 0.4-0.5e20 m-2, LSN, cryopump. Good outer gap
evolution.
Next shot: load locked-mode shot 1100721006 so Matt can calibrate HIREX rotation; also load
the corresponding engineering PLC timings
|
| Aug 11 2010 11:50:03:193AM | 1100811008 | Robert Granetz |
Shot 08 -- Plasma, locked-mode calibration shot, disrupted at t=1.58 s; locked at t=0.71 s.
0.8 MA, 5.4 T, 0.4e20 m-2, LSN, cryopump.
Next shot: reload the previous 8 tesla shot, 1100811007, along with the engineering PLC timings;
change nl_04 to 0.55e20 m-2
|
| Aug 11 2010 12:06:18:843PM | 1100811009 | Robert Granetz | Shot 09 -- Plasma, full length. 0.8 MA, 7.9 T, 0.6e20 m-2, LSN, cryopump. Next shot: repeat, no changes |
| Aug 11 2010 12:33:17:953PM | 1100811010 | Robert Granetz | Shot 10 -- Plasma, full length. 0.8 MA, 7.9 T, 0.6e20 m-2, LSN, cryopump; startup is degrading again Next shot: increase nl_04 to 0.7e20 m-2; add -0.2 mT to BR_0 (offset is now 0.0000 T) |
| Aug 11 2010 12:46:53:923PM | 1100811010 | Robert Granetz | I've noticed that the TF is not getting to flattop until t=0.7 s now (shots 7, 9, 10), whereas it reached flattop by t=0.6 s on shot 6). So the TF magnet must be heating up. Jim Irby is checking this. |
| Aug 11 2010 01:07:19:513PM | 1100811011 | Robert Granetz | Shot 11 -- Plasma, full length. 0.8 MA, 7.9 T, 0.8e20m-2, LSN, cryopump Next shot: tweak nl_04 to 0.65e20 m-2 |
| Aug 11 2010 01:38:28:007PM | 1100811012 | Robert Granetz | Shot 12 -- Plasma, full length. 0.8 MA, 7.9 T, 0.7e20 m-2, LSN, cryopump Next shot: set nl_04 to 0.85e20 m-2; increase argon pulse to 60 ms (was 50 ms) |
| Aug 11 2010 02:00:18:617PM | 1100811013 | Robert Granetz | Shot 13 -- Plasma, nearly full length. 0.8 MA, 7.9 T, 0.95e20 m-2, LSN, cryopump Next shot: set Ip to 1.2 MA; set nl_04 to 0.5e20m-2 |
