1091208, (tuesday) SL-plan for Run: 1091208 MP572: Detailed scan of low collisionality H-Modes SL: Dominguez PO: Irby The objective of this MP is to expand the database of the low collisionality H-mode regime and the measured parameters of these plasmas. The collisionalities that we are looking for are in the order of nu_eff<4 where nu_eff=0.1 Z_eff R/^2 where <...> is volumed averaged, density is in 10^(19)m^(-3), R is in m and Te is in keV. One particular regime that is sought is q95>7, which will be targeted using Ip~400kA. The solicited diagnostic set is: Correlation Reflectometry O-mode fixed reflectometry Core and Edge Thomson PCI Fast magnetics HIREX Sr HIREX Jr Cryopump GPI VB FRCECE D(alpha) GPC Passive CXRS Active CXRS and GPI (at the end of part A (if it's going well) and for part B) (Impurity injector will play it by ear) For future runs, it is intended to also include: CXRS (using DNB) and MSE. Boronization: overnight (standard setup (without D2 ECDC)). Target boronization parameters: 10% deuterated diborane/90 % helium dP: 120 psi TC6: 80 mTorr rmin/rdwell/rmax: 44/52/103 cm tdwell/tsweep: 60/120 s Pulsar set @ .7 on/ 0.3 off EF4 current: 0 A Post boronization ECDC ---------------------------- 1st Gas Setup: Gas: He sweep: 44/45/103 cm scan: 20/120 s Pressure: 5e-5 Torr Duration: 2 hrs ----------------------- -------------------------------------- Run plan: Since we'll be using the J antenna, HIREX Jr. will likely have pickup, making it hard to calibrate the velocity from HIREX Sr., so we'll start the day with a controlled locked mode shot in order to calibrate that way: shot 1: Use shot 1091113011 as HIREX Sr. velocity calibration We will begin with part A of the MP572 experimental plan (ne20=1.5 in the outer half of the plasma). For these shots, we'll begin with Ip~0.6 MW and vary SSEP in order to modify the ne profiles (as SSEP sweeps from LN -> UN it is expected to lower the ne profile). shot 2: Use 1070614017 as target shot to start with: Ip=600kA nl04 target= 7E19 ICRF=3.5MW @ 0.7s-1.2s SSEP scan -3mm -> +5mm from 0.7s-0.9s based on shot 1070614017, the strike point should be moved slightly upwards in order to not hit the W tile. ----------------------------------------------------- Due to the exotic nature of 1070614017, it'll be a difficult shot to reproduce. If by shot 5 we haven't been able to get a stable H-mode with similar characteristics, we'll switch to shot 1091022025, but lowering the current to Ip~600 to try to reach the right density condition -------------------------------------------------------------- shot 3-19: Depending on reproducibility of the shot, decrease Ip in 50kA steps from shot to shot to scan q95 (and lower density) in order to reach values q95>7. The main priority is to maintain steady EDA H-modes throughout the reflectometry time window (500ms). Span the range: ne(r/a~1)=1.5E20 -> ne(r/a=1)=1E20 from shot to shot. Lower the current until H-Mode becomes unsteady then increase in 10kA steps. nl04 will be modified depending on the effect of the current variations. If by shot 15 we haven't reached the ne(r/a=1)=1E20 or the q95>7 condition, concentrate on fulfilling that goal until shot 19. If part A is going well, use active CXRS and GPI during the H-mode Possible shots that have a density profile that resemble the target n_e: 1070614013 1080125022 1080125023 1080125024 ------ Second 1/2 of the day, concentrate on part B of MP572 (ne20=2.43 in the outer half of the plasma). For these shots, we'll start with Ip~0.8MW. shot 20: Use 1091022024 as target shot: Ip=800kA nl04 target= 8E19 ICRF=2.5MW @ 0.7s-1.2s SSEP maintained at -5mm shot 21-(end of the day-1): Depending on reproducibility of the shot, decrease Ip in 20kA steps from shot to shot to span the range: ne(r/a~1)~2.43E20 -> ne(r/a=1)~2E20. The main priority is to maintain steady EDA H-modes throughout the reflectometry time window (500ms). Last shot: repeat HIREX Sr. calibration Possible shots that have a density profile that resemble the target n_e: 1091022025 1091022031 1091022032

Many peaked H-modes during the run. We've expanded the database for q95>7. A few H-modes long enough to fill the whole reflectometry window. nu_eff will be calculated to see how they fit in the Greenwald scaling. Correlation lengths still need to be calculated but the signal from the channels seem to have pretty low S/N. Amanda was interested in some of the very low density shots (e.g. 14,15) for LH scenarios. Most of the diagnostics called for were operational except for the FRCECE system and all DNB related diagnostics. It looks like using only He ECDC was helpful in sustaining the low densities required for part A. As expected, the 1070614017 shot was difficult to reproduce. Shot 1-4 were having difficulties with ICRF (3 was the only fizzle of the day). Starting shot 5 we started getting short H-modes but it looks like the SSEP sweeps were not helping the ICRF coupling, this probably lead to the L-H back-transitions. Shot 8 had the first long H-Modes in which we saw the expected peaking. Several H-modes were produced but not long enough for the whole reflectometry window, so on shot 14 it was decided to go quickly into USN (SSEP +0.8cm) to try to repeat some H-modes found late in the SSEP sweep for previous shots. Shot 14 had a nice long EDA H-mode throughout the reflectometry time window. Unfortunately, 14 was pushing the EF2U supply to its limit. ne(r/a~1)~1E20 for this shot, so the plan was to slowly rise the ne profile from shot to shot to fulfill part A. Shots 15-18 were used to tweak 14 but it didn't seem to recreate the desired H-modes so it was decided to switch to using 1091022025 as the target (holding SSEP positive and lowering Ip to 625kA for shot 19) Shot 19 was a very stable EDA close to the density for part A (a bit too high) 20: repeat (moving X mode)- not great 21: repeat 19 with Ip=575kA...Good long EDA 22: Increase ICRF to 4...not great: RF tripped 23: Ip~485kA ICRF not responding great. 24: Ip~475kA ICRF not responding great but longish EDA? H-mode 25: Again, long EDA for part A 26: Controlled locked mode for HIREX Sr. Calibration 27-29 variable frequency was set for 110-116 so no high frequency data 27: Switch to part B. Reload 1091022024. Worked relatively well but the H-mode increased out of the desired range 28: Increased RF but is seems to take ne in the opposite direction 29: First shot with variable reflectometer from part B. Two H-Modes in the time window...density seems to be changing through the H-modes. 30: Good peaked H-Mode throughout the window 31: Blinked H-Mode in the window 32: Tried to force a low ne H-mode by creating a notch in ICRF. It did, in fact kill the first H-mode and create a second, but the second also blinked.

The machine startup up was very good today with only one fizzle (03). We used the startup from Friday's run. The cryopump ran all day and very reliably. No plasmas were lost because of the cryopump today. We began with a reload of 1070614017 which required re-cals on all magnetics predictors in all segments. This shot used ssep control and turned out to be very hard to modify as required by the session leader. The EF2U supply spent much of its time on the rail until Steve Wolfe made some changes to its gain and the EF4 programming. The discharges were then somewhat better, but we still had very little control of triangularity or the upper null configuration. Some useful data was obtained however before we switched over to 1091022025, which was a much more controllable configuration. We immediately got a nice long h-mode discharge at a relatively low density as asked for by the session leader. The discharge had relatively low radiated power, but the upper strike point was well into the cryopump slots, and we felt that we should reduce RXU and move it over a tile or so, to reduce possible damage to the tiles. We successfully moved the strikepoint, but the radiation in fact increased and the quality of the h-mode degraded. Moving the strikepoint back to the original position restored the quality of the discharge (an interesting discovery). Problems: . FMIT#2 ran w/o plasma on shot 01. It's not clear as yet if we did damage to the antenna or feedlines. . No TMX supplies on shot 01

Session Leader Comments
Dec 8 2009 08:36:47:463AM	1091208001	Arturo Dominguez	We'll skip the controlled locked mode shot since we expect the 1070614017 shot to be pretty difficult to reproduce. We'll hope to get the necessary Hirex Jr. data from the Ohmic part or from a steady EDA part. We'll start, then, with the 1070614017 target shot
Dec 8 2009 09:05:44:743AM	1091208001	Arturo Dominguez	Fizzle Andy said: "No TMX" that explains it We'll try it again
Dec 8 2009 09:29:02:637AM	1091208002	Arturo Dominguez	Plasma ran until 1.5s RF didn't run as planned Looks like the shape is similar to the target shape One more time
Dec 8 2009 09:44:04:900AM	1091208003	Arturo Dominguez	Fishizzle The RF that appears is actually going into the dummy load so it's NOT the same as in shot 1. Try again
Dec 8 2009 10:00:34:167AM	1091208004	Arturo Dominguez	Plasma ran well but the J antenna didn't hold well...the plasma went into a small H-mode bump but stayed in L-mode. J will run at lower power for next shot
Dec 8 2009 10:18:31:417AM	1091208005	Arturo Dominguez	Plasma full length It looks like J-port is coming along We got a brief H-mode. We think SSEP might be overshooting so we'll try to keep it closer to DN for shot 6. Small power increase from J-port It looks like we might still get it in this configuration so we'll stay here instead of switching to the 1091022025 target for now.
Dec 8 2009 10:30:44:120AM	1091208006	Arturo Dominguez	Josh, can you ping the FRCECE computer to check if it's working now?
Dec 8 2009 11:32:46:090AM	1091208006	Arturo Dominguez	SSEP was changed so that it wouldn't go up as substantially in UN Still some issues maintaining the H-mode
Dec 8 2009 11:35:52:510AM	1091208007	Arturo Dominguez	SSEP sweep was delayed so as to leave time for H-mode to form H-mode at 1.15 looks EDA-ish and has pretty high peaking. Still not steady enough though.
Dec 8 2009 11:54:05:883AM	1091208008	Arturo Dominguez	For this shot, we lower the LN SSEP in order to stay away from the DN during the H-formation. H-Modes are looking very peaked.
Dec 8 2009 11:56:23:557AM	1091208009	Arturo Dominguez	Interesting shot for H-modes. There are 3 brief H-modes of which the second has the desired ne profile that we want to start with. The third H-mode is even lower density...very peaked: ne(r/a=1) ~ 1E20 so it's what we want to target for the end of part A. The Ip wasn't changed substantially.
Dec 9 2009 08:28:33:293AM	1091208009	Arturo Dominguez	The H-modes looks EDAish. There is substantial peaking on the second one but a bit higher than it's wanted...next shot, lower Ip from 600kA to 500kA
Dec 8 2009 12:35:20:233PM	1091208010	Arturo Dominguez	Shot 10 Disrupted at 0.5
Dec 8 2009 01:59:32:153PM	1091208011	Arturo Dominguez	Brief H-Mode when RF turns on
Dec 8 2009 12:47:03:950PM	1091208014	Arturo Dominguez	Great EDA low density H-Mode. Reflectometry window is in the right timing for the data. The ne(r/a~1) is close to 1E20 so we'd like to start raising the ne profile for next shot. next shot: nl04=0.8
Dec 8 2009 01:17:47:700PM	1091208015	Arturo Dominguez	Didn't go into H-Mode
Dec 8 2009 01:31:20:420PM	1091208016	Arturo Dominguez	We raised the Ip by 50kA There are two consecutive H-modes...the second one looks like it's in the right density range. The timing window is set earlier so we only get the first ~200ms of it. we'll increase nl04 for next shot
Dec 8 2009 01:35:03:030PM	1091208017	Arturo Dominguez	nl04 was raised to 0.75 but there was only one small H-Mode
Dec 8 2009 01:58:01:390PM	1091208018	Arturo Dominguez	No H-Mode. It's looking too difficult to modify shot 14 to scan density using this as the target. We'll switch from this to using 1091022025 as our target shot while lowering the Ip to about 600kA to lower the density to our target one. I believe we lost the cryopump for shot 19
Dec 8 2009 02:20:41:827PM	1091208019	Arturo Dominguez	Great shot....a bit higher density than I would've liked,, but it looks like this is a good target. For 20, the top X point was moved to the left.
Dec 8 2009 02:21:41:733PM	1091208020	Arturo Dominguez	Not as good as 19. A few brief EDA H-mode. Will repeat 19 lowering Ip to 550kA
Dec 8 2009 02:52:30:297PM	1091208021	Arturo Dominguez	We lowered the current by 50kA Great EDA H-mode in the time window. ne profile is lower.
Dec 8 2009 03:31:56:607PM	1091208026	Arturo Dominguez	For this shot we'll load 1091113011 to get a controlled locked mode in order to calibrate the Hirex sr. velocity.
Dec 8 2009 03:43:52:670PM	1091208027	Arturo Dominguez	We'll start part B: reload shot 1091022024 with Ip=750kA
Dec 8 2009 03:59:52:827PM	1091208027	Arturo Dominguez	H-mode starts well and then there is a change at t~1s which increases nl04 out of the desired range...D(alpha) looks like it's showing L-H dithering but nl04 doesn't see it. Not an easy shot to explain
Dec 8 2009 04:44:02:110PM	1091208030	Arturo Dominguez	We'll repeat the last shot because the variable frequency channel was still set at 111GHz-116GHz. This has been fixed for this shot. Shot ran well. Good density profile at least up to t=1s.
Dec 8 2009 05:04:57:840PM	1091208031	Arturo Dominguez	For shot 31 we'll decrease Ip by 50kA. We got 2 H-modes of interest. We'll repeat it with a shifted reflectometry time window: 1-1.5 And with an RF notch at 0.9s
Dec 8 2009 05:13:06:810PM	1091208032	Arturo Dominguez	repeat shot 31 reflectometry time window: 1-1.5 with an RF notch at 0.9s It looks like we got 2 H-Modes in the reflectometry time window. the second looks like it's in the right density range. End of run....THANKS EVERYONE

Dec 8 2009 08:24:18:557AM	1091208001	Jim Irby	load from 1070614017 did recals on all magnetics predictors in all segments loaded --- open tree done imported seg 1 from 109120403 into seg 1 loaded We successfully boronized last night. We will be running with the cryopump for the first shot: trying 55 ms of gas Fizzle still set up on wrong shot. Will change after we get going.

Dec 9 2009 07:16:32:510AM	1091208001	Jim Irby	Note from Steve Wolfe following loss of F15 last September indicating how to do all the required magnetics recalculations: Physics Operators- On Thursday, Sep 24, 2009, the partial flux loop F15 became critically unreliable, failing on essentially every shot despite repeated "zapping" by Bob Granetz. There is some irony in the fact that it was probably intentional disruptions produced by Bob's gas jet that finally did the loop in, but it has been intermittently failing with increasing regularity for a couple of weeks. Fortunately, the F15 loop signal can be replaced by combinations of other loops on the outer wall, so an in-principle exact software workaround for the loss of this signal is available. Unfortunately, the previously coded implementation of this workaround turned out to be buggy, so we lost six hours on Thursday instead of just one or two. New predictor algorithms have now been prepared and successfully tested off-line, and will be used during plasma operation today. When loading shots or importing segments from shots earlier than 1090925001 you will get the Configuration ID Warning message, telling you to "recalculate all magnetic predictors". As usual, this means you will need to 1) go into the Edit Wire screens for each of the magnetics predictors (BR_0,BZ_0,RCUR,ZCUR,RXL,ZXL,RXU,ZXU,SSEP,STRKPSI) that appear in any loaded or imported segment, noting any values in the OFFSET column 2) hit the CALL button for all rows that have an algorithm name other than CLEAR or CUSTOM 3) Replace any non-zero entries in the OFFSET column which get reset to zero by the CALL. 4) APPLY (or OK) the screen, 5) OK the Factor screen when it pops up, and also any P_INFO warnings that appear. You do not need to, and generally should not, re-Call predictors for the coil currents, NL04, B21_PROJ, EF2_BY_EF4, or IP as part of this fix. You should do the preceding operations #1-5 for all segments if you have re-loaded an old shot, but if you do not want to take the time to do this for unused segments, then please hit the "Zero" button (bottom of the segment column, first button int the last row above the "DPCS Loadable Procedures" box, so that non-fixed predictors aren't left around for the next operator. Since this fix involves removing a signal from the predictors, the automatic check_predictor routine will flag any wires in active segments which still contain the bad signal by popping up a warning widget during LOAD. If this happens, you need to acknowledge the pop-up, noting which wire(s) are affected, and when the load completes go back and fix the problem. You can test whether you've missed any wires by doing a BUILD_ALL (button just to the left of LOAD) before doing the LOAD. -- Stephen M. Wolfe M.I.T. Plasma Science and Fusion Center
