Session Leader Plan for 1110317

MP 649: Scaling of parallel impurity transport with Mi, q95 and vi

This run will focus on running L-mode plasmas with large amounts of on-axis D(3He) mode-conversion and D(H) minority heating in order to reach high toroidal rotation speeds (~100 km/s).
This run will be done at ~5.1 T with J-ANT at 50 MHz in D(3He) and D+E at 80 MHz for D(H) heating.

These plasmas will be used to study the in/out ratio of molybdenum density on a flux surface thought to be driven by centrifugal force by using LBO Mo injections and examing the 2D emissivity distribution using XTOMO and AXUV diode arrays.

A LSN plasma will be used since we're in reversed field and want to avoid H-mode. The current/density scans required by MP649 will be completed starting with a favorable target from 1110316 which will optimize mode-conversion flow-drive in I-modes.

***NO OVERNIGHT EC/DC****

GAS SETUP:
==========
main-ion: D2
B-SIDE-LOWER: 3.0 psi Ne for seeding as necessary for PFC protection
H-BOTTOM: 1.5 psi Ar for HIREXSR
NINJA - D2, leave disabled but possible at higher nl04 shots
***3He puffing for ICRF***

ICRF:
==========
J at 50 MHz 2-3 MW, D+E 80 MHz at 2-3 MW

DIAGNOSTICS:
============
all Te and ne diagnostics (TCI, TS, GPC1, GPC2, FRC). GPC1, GPC2 setup forfield 5.1 T. FRC for 5.4 T shots.
PCI for D(3He) mode-conversion observations, FICX 3He piggyback
HIREXSR, XTOMO, AXUV diodes, bolometry, XEUS, McPherson
Mo laser blow-off
DNB-based CXRS
divertor heat-flux diagnostics (probes/thermo/IR) for operations feedback
GPI diagnostics on standby, D2 puffing-only for high nl04 shots
reflectometer and magnetics as desired for I-mode analysis since we'll probably make them

EQUILIBRIUM:
============
TARGET: use 1110316019
LOCKED MODE: use 1110316021

SHOT PLAN:
============
1) run HIREXSR locked-mode calibration plasma

2) ICRF conditioning, diagnostic testing (Ip=0.9 MA, nl04~0.7)
2+ MW of J-ANT from 0.6-1.0, add 2+ MW of D/E from 1.0-1.4

A very useful day. We got through all of the run plan and had time for a few shots to try for high Te.
Between 1110316 and today I got a current scan from 0.7-1.3 MA by 100 kA at a range of densities and velocities. Now begins the immense amount of data analysis.

Shots 001,006 and 022 were locked mode calibration shots. We made the same flub as before on shot 001 that we left the Ne on. We disabled B-SIDE-LOWER for 006 but then forgot to turn it back on. Earl just removed the puff from the target shot for 022.

For 002-005 we worked to get back a demonstration shot yesterday, the 1110316019 reference. We then started the Ip and nl04 scans.

007-012 were 0.9 MA, nl04~0.65,0.47
013 was 0.7 MA, nl04~0.5
014-021 and 035-036 were 1.1 MA, nl04~0.95,0.67,0.8
023-034 were 1.3 MA, nl04~1.1,1.2,0.95,0.8,0.7

We had a number of issues with Mo injections, MARFEs and locked modes but not unexpected considering the parameter space we were covering. We had some trouble avoiding I-H transitions and limited the ICRF power coming from D+E.
We saw the same issue as yesterday with the rotation hitting a limit and not scaling with the WMHD at the I-mode transition.

The machine ran reasonably well today, although there were quite a few early disruptions, mostly associated with natural impurity influxes/injections and/or locked modes. Nevertheless, a good number of high performance I-mode shots were produced, and the session leader run plan was essentially completed, covering 4 plasma currents from 0.7 to 1.3 MA, with density scans at each but the lowest current.

Startups were reliable, with one fizzle, a few bouncers with early hard x-rays, and one shot with late breakdown that nevertheless ramped up. Minor tweaks to prefill and EF4 precharge current were made a couple of times. There was a short delay at the start of the day to resolve an ICRF breaker issue in the hi-yard. The cryo system interface PC had a problem after one of the shots, also causing a short delay.

Session Leader Comments
Mar 16 2011 05:11:14:733PMMatt Reinkereconsidered the overnight ECDC
perform ECDC as done for 1110316
Mar 17 2011 09:24:56:893AM1110317001Matt Reinkeload the 1110316019 target with some tweaks to check machine/RF status
D+E start at 1.0
LBO injectionst at 0.85 and 1.25

***need to wait for J-ANT to warm up***
instead run the locked mode (no ICRF/no injections) loaded from 1110316021

RESULT: the Ne went in, forgot to disable B-SIDE-LOWER, early disruption. No locked mode.

NEXT: move to ICRF target shot, turn on LBO
Mar 17 2011 09:32:18:217AM1110317002Matt Reinkeload the 1110316019 target with some tweaks to check machine/RF status
D+E start at 1.0
LBO injectionst at 0.85 and 1.25

RESULT: fizzle

NEXT: retry
Mar 17 2011 09:53:21:263AM1110317003Matt Reinkeretry the ICRF target

RESULT: early disruption at ~0.3. Looks like there was an Fe injection. AXUV diodes and the hailstorm on the LH camera suggest it came from the A-PORT area.

NEXT: repeat
Mar 17 2011 10:04:14:857AM1110317004Matt Reinkestill trying for target

RESULT: early MARFE and disruption, Ar screams up and is ~x2 of the target shot.

NEXT: reduce Ar (50 V) and repeat
Mar 17 2011 10:23:46:767AM1110317005Matt Reinketrying for target shot

RESULT: good repeat of ICRF example from 1110316. the target density reaches the same prior to the ICRF turn on then density rises a bit higher.
The 0.85 injection is clean but the 1.25 was into the ~H-mode.

NEXT: run the locked mode shot and then start the scans in the SL_PLAN
Mar 17 2011 10:39:14:260AM1110317006Matt Reinketry for the HIREXSR locked mode calibration shot

RESULT: great locked mode, velocity decays to ~+4 km/s so we're in good absolute velocity calibration

NEXT: begin Ip/nl04 scans from SL_PLAN Ip=0.9, nl04=0.5
Mar 17 2011 10:56:00:500AM1110317007Matt Reinkestart the Ip/nl04 scan 0.9 MA, nl04=0.5
also put 70 V on the Ne puff. Forgot that I increased the pressure to give me some headroom at higher Ip

RESULT: good RF but very poor density control also the Mo LBO's weren't significant

NEXT: repeat with improved LBO, also increase Ar to 70 V to try and increase signal during ICRF pulse
Mar 17 2011 11:08:30:903AM1110317008Matt Reinkeretry the 900 kA shot

RESULT: early injections, Mo and Fe

NEXT: repeat
Mar 17 2011 11:24:32:523AM1110317009Matt ReinkeIp=0.9, nl04=0.5 target

RESULT: still bad LBO and had some large unauthorized Mo injections

NEXT: repeat w/o D+E to try and remove big injections (from limiter heating?)
Mar 17 2011 11:31:43:407AM1110317010Matt ReinkeIp=0.9, nl04=0.5 w/o D+E

RESULT: nice steady plasma, the 0.85 injection is polluted but the 1.25 is good

NEXT: increase nl04 to 0.7
Mar 17 2011 11:44:29:823AM1110317011Matt ReinkeIp=0.9, nl04=0.7

RESULT: LBO's are right after the ICRF so we didn't get clean data

NEXT: repeat but add another LBO at 1.05 to make sure data is collected
Mar 17 2011 11:54:43:587AM1110317012Matt ReinkeIp=0.9,nl04=0.7
also noticed that we've been w/o the Ne puff since we did the LM (006) that might be what's causing some of the Mo problems.
Will re-enable when going to high current.

RESULT: good shot w/ 2 of the LBO's clean

NEXT: move to lowest current point, Ip=0.7 and nl04=0.5
Mar 17 2011 12:10:30:173PM1110317013Matt ReinkeIp=0.7 and nl04=0.5

RESULT: got two good Mo LBO

NEXT: up to the high Ip points
Mar 17 2011 12:23:08:620PM1110317014Matt ReinkeIp=1.1 MA, nl04=0.9
re-enable Ne puff and use the ICRF waveform from 009
NINJA firing at 1.1 seconds
reducing back to 0.85 and 1.25 Mo LBO's

RESULT: good injection at 0.85, but get an H-mode during the 2nd ICRF pulse

NEXT: lower D+E power
Mar 17 2011 12:35:43:477PM1110317015Matt Reinkerepeat shot w/ lower D+E power (3.9 MW total w/ J) to avoid I/H transition

RESULT: the 2nd LBO injection is once again masked by an unauthorized Mo.

NEXT: lower D+E again to 3.5


Mar 17 2011 12:48:08:097PM1110317016Matt ReinkeIp=1.1, nl04=0.9, lower D+E to avoid H-mode
increase to x3 LBO's at 0.85, 1.15 and 1.35 to try and make up for my terrible luck with injections

RESULT: early disruption, but the 1.15 injection is clean so move on

NEXT: Ip=1.1, nl04=0.7
Mar 17 2011 01:03:20:580PM1110317017Matt ReinkeIp=1.1, nl04=0.7
turn NINJA off, same ICRF pulse

RESULT: locked mode ~ 0.48

NEXT: Have the PO tweak the nl04/ip ramp part of the shot and repeat
Mar 17 2011 01:18:21:197PM1110317018Matt ReinkeIp=1.1,nl04=0.7
repeat w/ PO magical fixes

RESULT: good shot, two of the LBO's are good

NEXT: lower the target density to 0.5
Mar 17 2011 01:26:39:030PM1110317019Matt ReinkeIp=1.1, nl04=0.5

RESULT: hit a locked mode and early disruption

NEXT: move back up to nl04 to avoid the locked mode, increase the ICRF power to increase the temperature to lower the collisionality
Mar 17 2011 01:40:36:883PM1110317020Matt ReinkeIp=1.1, nl04=0.7 but w/ increased D+E ICRF heating

RESULT: disruption at ~1 sec due to a Mo injection that started just before D+E came on

NEXT: repeat
Mar 17 2011 01:55:31:433PM1110317021Matt ReinkeIp=1.1,nl04=0.7

RESULT: got two of the LBO's on this one, end of 1.1 MA shots

NEXT: locked mode shot, then move to 1.3 MA
Mar 17 2011 02:02:08:370PM1110317022Matt Reinkelocked mode shot for HIREXSR calibration

RESULT: good locked mode, voffset ~ +5 km/s

NEXT: move to 1.3 MA, nl04~1.1

Ip=1.3, nl04=1.1
enable NINJA

RESULT: early MARFE and disruption in current ramp, looks like nl04 is too high too early

NEXT: PO adjustment of density rise and repeat
Mar 17 2011 02:35:25:390PM1110317024Matt ReinkeIp=1.3, nl04=1.1
