MP 692 : Formation of ITB in I-mode Plasmas (for use as 2-D high-Z impurity transport studies)

SL: M.L. Reinke
PO: E. Marmar

This run day will be dedicated to the first ever investigation of the influence of poloidally varying impurity density on flux-surface averaged radial transport. Strong in/out asymmetries have been demonstrated in C-Mod driven by centrifugal force and poloidal electric fields sustained by ICRF heating and these are predicted to have an influence on radial turbulent transport. On 1101208, the pre-cursor to MP 692, control of these in/out asymmetries was demonstrated (in piggyback) using resonance layer scans and these observations were repeated on 1120830 when MP 692 was first run.

Another day of MP 692-like plasmas (LFS/HFS off-axis heating in I-modes) will be run to obtain detailed radial and poloidal impurity density profiles. Plasma with matched Te and ne will form discharge pairs with LFS and HFS accumulation in which the RADIAL impurity peaking can be compared. A scan of Bt at fixed Ip and (nearly) fixed q95 will be done at the same density.

Zeff is also an important factor in determining the poloidal asymmetry so Ne and GPI He puffing will not be used (if possible) and argon for HIREXSR kept to a low level. Molybdenum laser blow off will be used to study the radial impurity transport and enhance the Mo content for estimating of the in/out asymmetry.

In order to aid matching LFS and HFS heating, the density will be scanned during the ICRF pulse using the NINJA (see shot plan). Core fluctuation diagnostics used on 1120830 should also be enabled in order to add more data to the MP 692 data set.

Today we obtained L/I-mode plasmas with molybdenum laser blow that were configured to have varying levels of in/out impurity asymmetries at nominally fixed ne,Te and a small range of q95.

This was accomplished by varying Bt to alter the minority resonance location and Ip to adjust the q95. For LFS heating, strong HFS impurity accumulation, up to nz/ ~ -0.2 was observed while for HFS heating, centrifugal effects dominated at nz/ ~+0.3 was seen. It was difficult to obtain matched plasmas in these conditions since although we know qualitatively how to vary the asymmetry, it's far from being able to be "dialed-up" by the PO.

The laser blow-off performed well with the new lens that adjusted the focus to account for movements driven by the RFQ placement at B-Port. In most plasmas signal was easily observed above background on HIREXSR and SXR tomography, although in some cases clear I/L back-transitions were induced by the Mo radiation.

The day began with difficulty after ~2 hours of data system problems. Josh blamed them on my lack of bringing food, but I claim such problems WITHOUT food is clearly the outlier based on recent data. Earl/Jim allowed the run to go till 6:00 pm to help make up for the lost time. We were able to get through the run plan and have time for a few extra intra-shot Bt scans.

Shots 10,11 were 5.4 T shots to demonstrate proper machine operation
Shots 12,13 were locked mode attempts...still haven't gotten a good one but these showed decent velocity "zero"
Shots 14-22 were LFS heating shots
Shots 23-37 were HFS heating shots

A problem with Module#3 on HIREXSR was reported AFTER the run, but apparently from shots 019-037 we only had 1,2 & 4. This will limit the up/down asymmetry studies/corrections but should still allow 1-D profiles analysis.

A big complication for this run was the limiter heating and the L/H or I/H transition. At the highest Bt and low nl04, we ended up with an injection from the shoelace/QCM antenna (shot 020). Because we wanted multiple injections and thus long pulses, we were limited in P/ne due to limiter heating. When we went up in density to avoid pulling out the tail, we hit H-modes. Wolfe suggested using some hydrogen puffing to try and pull the fast-ion distribution back, which would actually be a great idea for future (if any) iterations of this experiment.

There isn't any direct way to tell yet if the asymmetry level made much different in the radial transport. I observed some variation of the confinement time, but detailed analysis is required even for initial results. I'm fairly confident we have at least ONE matched pair of shots, though.

NEXT: move on to #3a
Sep 13 2012 12:10:25:700PM1120913014Matt ReinkeMove on to Section #3 - Ip=1.0, Bt=5.9

RESULT: good L/I-mode. Strong HFS accumulation. NINJA had H-mode transition and forget to set HIREX back to fast timing

NEXT: increase Bt to 6.1 T and Ip to 1.2 MA
Sep 13 2012 01:13:41:497PM1120913018Matt Reinkemoving to #3d 6.1 T, 1.2 MA - worried about limiter heating so test out at higher Ip first. Dropping ICRF back down to 3.0 MW.

Sep 13 2012 01:25:17:200PM1120913019Matt Reinkeset nl04 back to 0.8, increase ICRF power to 3.5 MW but decrease pulse length to end at 1.2 seconds. Remove NINJA pulse.

RESULT: injection at 1.0 seconds looks to be from the ASP - BAD DAN!!! HIREXSR data collection failure.

NEXT: repeat
Sep 13 2012 01:53:20:267PM1120913020Matt Reinkerepeat 019 to get HIREXSR data

NEXT: move to HFS heating
Sep 13 2012 02:49:56:157PM1120913023Matt ReinkeMove to #4a 4.9 T, 1.0 MA, first LFS heating point

Sep 13 2012 04:02:51:027PM1120913027Matt Reinke#4b' 4.8 T, Ip=0.9 MA

RESULT: good shot, density is a little low, but got the right q95

NEXT: move to #4c' 4.6 T, Ip=1.0 MA raise nl04 to match earlier shots
Sep 13 2012 04:15:58:627PM1120913029Matt Reinke#4c, 4.6 T, 1.0 MA raise nl04 to 0.9

NEXT: drop density and ICRF power to sit below L/H or I/H threshold
Sep 13 2012 04:29:55:673PM1120913030Matt Reinke#4c' 4.6 T, 1.0 MA drop nl04 to 0.83, ICRF to 2.8 MW

Sep 13 2012 04:41:29:823PM1120913031Matt Reinke#4d' 4.6 T, 0.9 MA

RESULT: good shot, late H-mode transition again

Sep 13 2012 05:15:30:970PM1120913033Matt Reinke#4d' 4.6 T, 0.8 MA w/ higher ICRF power and no NINJA

RESULT: H-mode transitions everywhere! Do not think I can get an effective q95 match here.

NEXT: increase back to 1.0 MA and do intra-shot BT scan
Sep 13 2012 05:24:10:487PM1120913034Matt Reinke#5a - scan Bt during the shot 4.6-5.3 T over 0.7-1.4 seconds, increase Ip to 1.0 MA

RESULT: got H-modes but managed to get the last injection clean, density was a little high

NEXT: reduce nl04 and Bt ramp rate and repeat w/ RF at 3 MW
Sep 13 2012 05:42:03:560PM1120913035Matt Reinke#5a - Bt ramp up to 5.2 T, nl04 target to 0.7 and drop ICRF power to 3.0 MW, increase to x4 LBO's at 0.7,0.9,1.1,1.3

RESULT: got nice strongly rotating LFS peaked case at slightly higher Bt, but nl04 drop led to some limiter/QCM heating

NEXT: keep 5.0 T flat, adjust nl04 programing to prevent drop, add NINJA
Sep 13 2012 05:57:16:553PM1120913036Matt ReinkeThis would be more to a point from #4 since Bt is fixed at 5.0. Getting some ELMs in this area so NINJA wants into the mix.

RESULT: good steady x4 injections and strong rotation, but weak asymmetry

NEXT: increase Ip,nl04 ramp during ICRF pulse
Sep 13 2012 05:58:00:353PM1120913037Matt ReinkeIncreasing Ip to 1.1 MA and putting in a density ramp during the ICRF pulse

RESULT:

NEXT: end of run
