MP 534: Foil/AXUV Bolometer Calibration in Helium SL: M.L. Reinke PO: S. Shiraiwa 1/2 - day run (9:00 am - 1:00 pm) This run will use He plasmas seeded with Ar and heated with ICRF to achieve high radiated power in an effort to cross-calibrate the resistive bolometers and the AXUV diode measurements. Additionally, the He plasmas will be used to demonstrate good "zeros" on the Lyman-a diagnostics indicating scattered light or filter issues are not a problem. Lastly, due to recent issues with fluorine contamination, we will explore USN and LSN ICRF heated plasmas to check the severity of the impurity influx. This run will also test a novel HIREXSR calibration method using KCl fluorescence in reflection mode. ECDC in He overnight Breakdown in D2, run main-ion as He from shot 001 Fill B-SIDE lower with 2.5 psi Ar, set PG3 voltage to 0.5 V (or whatever 50% duty cycle is these days) fill H-BOT with 15 psi N2, leave disabled DIAGNOSTICS: AXUV-diodes, XTOMO, resistive bolometers, divertor visible spectroscopy, LYMAN-a diodes. VUV/SXR spectroscopy. HIREXSR. LSN target: 1120124010 (5.4 T, 800 kA, nl04=0.8) USN target: 1120104018 (5.4 T, 800 kA, nl04=0.6) 1) load USN target, turn Ar puff on from 0.4-0.7, ICRF (D+E only) 2-2.5 MW from 0.5-1.4. 2) adjust ICRF/Ar puff to reach high PRAD/PIN, repeat as He-level is reduced and D2 removed from PFCs. 3) switch to LSN, disable Ar, no ICRF, Ohmic only test shot 4) increase ICRF power, testing impurity generation problems, H-modes are OK. If no issues, continue in LSN until lower divertor is outgassed of D2 (check visible spectroscopy) 5) take target from (4) or (2) and repeat with N2 seeding

Got good data for the bolometer calibrations and some of the Lyman-a diagnostics. The divertor deuterium emission never really went down significantly even after the confinement plasma changed over to He main-ion. We were able to run 2.5 MW into LSN and USN plasmas without any F issues. The USN, rf-heated plasmas almost all terminated in early disruption. Some were caused by Ar accumulation in a MARFE'ing plasma while others were due to W injections. This is presumed to be due to the UDIV probes and we tried sweeping to not much success.

2 very good shots for the program, and 5 more shots partly analyzed only 90° degrees phasing, we did not reach the 70° shot... 1. 1st Part : - 3 shots for LH power ladder: 1120131021, 22, 24 (23 no LH power) Launcher 3mm behind the main limiter Up to 550kW but with a lot of trips from 1s => We donâ??t see a clear dependence of RC with LH powerâ?¦ - Beautiful density scan at low power (200kW) with the same launcher position - the density scan at high power not performed because of high neutral pressure... 2. 2nd part : - we put the launcher ~ 6 mm behind the main limiter, in order to change edge plasma conditions (density profile and temperature) But too front density, the LH power is not coupled.. Then we move the launcher 2mm closer to the main limiter to do the power ladder, but still not coupled, only the end ot the power ladder.. After that, we move the plasma 5/6 mm closer to the main limiter : almost the same.. 2 last shots : Network issue 5pm

Today, the machine worked reasonably well, although we had several issues including network problem. The first half was spent to run MP534. We break down using D2 and used He as main spices. From shot 5 to 14, USN configuration was used and we had repeated obtained MARFE and W injection. Plasma became better after we switched to LSN (shot 15 to 20). The second half (after #21) was devoted for MP666. However, except for the very first case, we had problems caused by the combination of network, coupling (density control in front of the launcher), and the new LH protection system. We were able to obtain 12 full pulse length discharges out of 13 attempt. Among them, about 7 shots had a LH pulse long enough for further analysis. Following is today's score card.

Session Leader Comments
Jan 31 2012 09:57:34:683AM	1120131005	Matt Reinke	RF looks nice but target shot is nowhere near what I asked for. wanted: 800 kA, nl04~0.6 got: 500 kA, nl04~0.2-0.3 No real He line-emission on LoWEUS, density demand is so low that D2 breakdown and wall fueling is enough, no He puff needed.
Jan 31 2012 10:02:39:227AM	1120131006	Matt Reinke	runaway protection fired
Jan 31 2012 10:26:14:920AM	1120131007	Matt Reinke	W injection near the RF turn-off. Likely the cause of the disruption. Dan's checking UDIV probes. Good RF and nl04 traces. PRAD steady ~ 1 MW. NEXT: Increase PG1 (Ar) voltage to 75 V, increase nl04 to 0.9 Also putting in a small upper x-point sweep to avoid too much energy flux.
Jan 31 2012 10:36:13:543AM	1120131008	Matt Reinke	Strong MARFE, but got a nice PRAD ~ 2 MW shot. Density is over shooting by about 0.1 NEXT: Increase Ip to 900 kA, decrease nl04 program to 0.7 to try and avoid the MARFE. Increase RF power to 2.5 MW (D+E only).
Jan 31 2012 10:53:48:807AM	1120131009	Matt Reinke	Another W injection ~1.09 seconds, even with upper strike point sweep. NEXT: increase nl04 to 0.8, lengthen Ar puff from be from 0.4-1.0 Removing sweep, lowering ICRF to 2 MW.
Jan 31 2012 11:07:02:253AM	1120131010	Matt Reinke	MARFE induced Ar accumulation lead to disruption. I seem to be stuck between a MARFE and a W-injection. NEXT: adjust upper strike point as per Wolfe suggestions, reduce Ar puff length to 0.4-0.9 seconds.
Jan 31 2012 11:18:42:697AM	1120131011	Matt Reinke	Last past the RF turnoff at 1.4 seconds but had a large MARFE. Even before MAREF, density creaping up. Getting good PRAD levels. NEXT: Reduce target nl04 to 0.7, increase RF to 2.5 and put in ramp down in ICRF into Ip ICRF.
Jan 31 2012 11:34:19:707AM	1120131012	Matt Reinke	Although we lost the MAREF, we got the W injection back. NEXT: Switch to LSN target, ohmic only, no ICRF, no Ar
Jan 31 2012 11:44:38:397AM	1120131013	Matt Reinke	LSN ohmic, density overshot due to programming/MARFE issues. No F issues. NEXT: enable 0.4-0.7 Ar at 50 V, 1 MW ICRF from 0.5-1.4 seconds. Lower target nl04 to 0.7.
Jan 31 2012 11:55:03:587AM	1120131014	Matt Reinke	Large early Fe injection at 0.32 before ICRF or Ar puffing.
Jan 31 2012 12:13:32:743PM	1120131015	Matt Reinke	Good LSN shot. Early Mo injection and MARFE but steady during ICRF. No F issues. NEXT: Raise ICRF power to 2 MW, increase Ar to 75 V.
Jan 31 2012 12:27:51:240PM	1120131016	Matt Reinke	Nice steady RF/PRAD until just after 1.0 when we pick up some L/H dithers. Too much PSOL...I have the solution to that problem. More Ar Igor! Still getting deuterium signal on Lyman and H-alpha tools. Actually midplane looks ok but the divertor is still has some D2 in it. NEXT: Increase Ar puff from 0.4-0.9, increase PRF to 2.5 MW.
Jan 31 2012 12:37:50:417PM	1120131017	Matt Reinke	Still have dithers. Still have divertor deuterium signals. NEXT: More Ar, set to 100 V.
Jan 31 2012 12:52:43:267PM	1120131018	Matt Reinke	D2 still hanging around in div. NEXT: Enable B-DIV (new seeding tube) with 11 psi of N2 at 75 V, from 0.8-1.1.
Jan 31 2012 01:01:40:120PM	1120131019	Matt Reinke	Phys Op error prevented the N2 puff from firing. Flipped Greg for an extra shot and won the coin toss. NEXT: Same as 019 but with the requested N2.
