I-mode with lower single null and unfavorable grad-B topology The purpose of these experiments is to characterize I-mode in lower single null topology with unfavorable grad-B topology. The experiment has several motivations and goals: a) exploit the better power handling capability of the lower divertor to further explore I-mode performance vs. shaping b) determine if the vertical target geometry in the lower divertor leads to consistently better confinement performance and c) document the I-mode power widths and peak heat flux using the better divertor diagnostic set in the lower divertor. We will build on the success of the previous I-mode campaigns with an emphasis towards the three main goals of the experiment: a) better â??fill outâ?? shaping space of triangularity and elongation b) characterize divertor response in I-mode c) document static and fluctuation features of the core and pedestal plasma during this exploration. Experiments will all be in counter-clockwise Bt and Ip with LSN x-point topology. We will keep the cryopump cold since it will still be of use since the secondary upper x-point streams outer SOL flux surface into the pump entrance. General parameters Bt = 5.8 T LSN Cryopump on Diagnostics: divertor heat flux, TS, ECE Starting shot: referenced from 02/14/11 startup run in reversed B (e.g. 1110214018) Shot Plan --------- 1. Establish reference for Ip scan at lower δ 1-3 shots Reference shape: #1110214018, Ip=0.8 MA, NL04 target ~ 0.7e20. Bt = 5.8 T 250 ms Prf steps: 2.0, 2.25, 2.5, 2.75 May have to vary target density for I-mode access. a) Obtain steady I-mode and document heat flux b) Assess optimal neon seeding for impurity control & measure heat flux. 2. Increase Ip at low low δ 5-6 shots Same as above but at i) 1.0 MA NL04~0.8 without neon seeding ii) 1.0 MA NL04 ~ 0.8 with neon seeding. iii) 1.25 MA, NL04 ~0.9 iv) 1.25 MA NL04~0.9 with neon seeding Again may have to tweak target density which generally needs to increase with Ip Success determined by obtaining sharper I-mode transitions + divertor heat flux Scan from here on will use optimal neon seeding. v) Repeat trying to hold I-mode constant throughout shot. 3. Lower triangularity scan at fixed current (I~1.2 MA or TBD) and NL04 and keep upper triangularity as fixed as possible: 5 shots a) Lower δ ~ 0.35, 250 ms Prf steps: 2.6, 2.7, 2.8, 2.9 b) Lower δ ~ 0.45 250 ms Prf steps: 2.6, 2.7, 2.8, 2.9 c) Lower δ = 0.6, 250 ms Prf steps: 2.6, 2.7, 2.8, 2.9 d) Lower δ = 0.7, 250 ms Prf steps: 2.6, 2.7, 2.8, 2.9 e) Lower δ = 0.75, 250 ms Prf steps: 2.6, 2.7, 2.8, 2.9 f) Lower δ = 0.8 , 250 ms Prf steps: 2.6, 2.7, 2.8, 2.9 4. Upper triangularity scan at fixed current, lower triangularity 4 shots Target lower triangularity will be chosen based on Step 3 a) Upper δ = 0.4, 250 ms Prf steps b) Upper δ = 0.5, 250 ms Prf steps c) Upper δ = 0.6, 250 ms Prf steps d) Upper δ = 0.7, 250 ms Prf steps e) Upper δ = 0.8, 250 ms Prf steps 5. Current or q95 scan at optimized triangularity and kappa. (4 shots) Choose optimal case from shaping scan and change Ip a) Ip = 0.8 MA b) Ip = 1 MA c) Ip = 1.2 MA d) repeat with constant power to hold I-mode steady. d) Ip = 1.4 MA

A successful day in that we saw new aspects of I-mode. Overall observation: I-mode characteristics at modest dominant triangularity (0.5) and/or with vertical target are different than our experiences at higher dominant triangularity in the upper divertor. The biggest "success" of the day was seeing a substantial increase in the power window for I-mode. The best examples of this are 1 MA, delta~0.5 shots: I-mode was obtained between 2.2 and 3.5 MW, with no H-mode transition. (When the power was slowly ramped up we ceased to see H-modes in the latter part of the run day.) This is significant towards demonstrating I-mode as a viable operating scenario, and (perhaps not surprisingly) shaping seems to play an important role. Control room assessment of WCM is that it was at higher frequency. Also the L-I transition (shot 17 for example) was qualitatively different: the pedestal T seemed to ratchet up every sawtooth crash, and after about 5-6 attained its stationary value. We obtained very good absolute performance at 1 MA in I-mode: H98~1.1-1.2, pedestal T > 1 keV. When we did get H-modes they were very high performance (although transient) with H98 > 1.5 routinely seen and 1e14 n/s. I-mode was also obtained at 0.8 and 1.25 MA in the standard LSN shape. We also saw interesting behavior in the lower triangularity scan at 1 MA. a) Moving to lower triangularity, thus moving the OSP up onto the nose, resulted in disruption-causing Mo injections, hinting that divertor power loading is important to that problem. b) A very surprising result: when the lower triangularity was bumped up to ~0.6, and the outer leg moved into the slot, the I-mode disappeared, despite matched density and ICRF power to delta_Lower~0.5 with the outer leg on the vertical target. The discharge just stayed in L-mode?? However we faced a learning curve about running in this configuration; in particular we struggled with Mo injections for much of the day. The source location of the injections is not clear. The inner divertor was significantly more attached than in favorable grad-B. Also, heat diagnostics at the outer divertor hinted at very high local heat flux (> GW/m2). As usual some combination of more density + neon helped. We were far from optimizing this but ran out of time We probably lost ~1/3 shots to technical issues like EF(1?) failure, Marfes and cryopump burps. And ~1/3 to injection caused disruptions. As a result we probably got ~1/3 -1/2 through run plan.

This was the first reversed field experiment following the bus modifications required for reversed field operation. Some critial work on developement of the discharge for this run was done on 1110214. The latter acquired the basic LSN discharge that we used to start this run. The discharge variations included small changes in density and plasma current. There were significant changes in the lower triangularity in terms of effect on the plasma. Large changes in the upper triangularity were less perturbative. There were upper and lower triangularity scans. The lower triangularity scan ran into inner and outer noses but seemed to accomplish the SLs basic requirements. Possibly appropriate to make a second attempt at the scan using a higher x-point. In this case, this would have added an additional varying quantity, elongation. A major problem during the run were the frequent impurity injections. While neon puffing was primarily for control of limiter and divertor loading, it also seemed to reduce the injection of impurities. Some injections caused disruptions. The I-mode experiment should have been quite simple, but the injections were a limit. The cryo pump was used for the first half of the run. It appeared to have little effect but for some operational problems which resulted in fizzles and delayed shots. It was not used from shot 016 on and its limited effect on the plasma was confirmed. The plasma was LSN, and the cryo is expected to have a stronger effect for USN. A EFC failures resulted in duds. These were due to a continuing engineering issue. Score Card 24 plasmas 01 no power shot; cryo problem during init 02 duds; EF1 failures 01 runaway shut down 011. runaway shut down. 03 fizzles ------------ 31 total

Session Leader Comments
Feb 15 2011 10:28:38:150AM	1110215001	Dennis Whyte	Reverse B 0.8 MA B ~ 5.8 Tesla Standard LSN with strikepoint on vertical target Lower delta ~ 0.5 RF ratty: will continue to condition
Feb 15 2011 10:28:17:420AM	1110215002	Dennis Whyte	Reverse B 0.8 MA, lower delta~0.5 RF starting to condition, 2 MW but uneven Three Mo injections: Last one at 1.05 disrupted the plasma. Will try again. May have to start Neon seeding?
Feb 15 2011 10:27:53:887AM	1110215004	Dennis Whyte	Reverse B 0.8 MA, lower delta~0.5 RF more steady H-mode at 1.35 s Several large Mo injections after 1.05 s. Inner divertor clearly hotter. Will tweak up density to try and reduce
Feb 15 2011 10:54:43:923AM	1110215005	Dennis Whyte	Reverse B 0.8 MA, lower delta ~0.5 RF constant. Impurity injections eliminated and constant Prad < 1 MW with this slightly higher density NL04~0.7 instead of 0.6 No H-mode transition up to 3 MW Note: high Pnet in this shot. Starting to look like I-mode with a Te pedestal based on TE/ECE. H98 ~ 0.85-0.9 through much of the shot. However no clear sign of WCM. Perhaps because of combo of low Ip and low delta?
Feb 15 2011 11:35:11:943AM	1110215008	Dennis Whyte	Reverse B 0.8 MA, lower delta ~0.5 Increased power but this led to several early H-modes even though the power was less than the 2.7 MW at end of shot 5 that did NOT have H-mode This behavior is similar as previous I-mode exploration in that earlier ICRF tends to trigger H-modes Fairly nice (transient) H-modes with high H98~1.4
Feb 15 2011 12:14:35:767PM	1110215009	Dennis Whyte	Reverse B 0.8 MA, lower delta ~0.5 Decrease powers but still H-modes There are signs that broadband fluctuations are decreasing before H-modes. Magnetics: BP6T_ABK shows WCM just before the H-mode transition Conclusion is that this is what I-mode might look like at this lower current and triangularity
Feb 15 2011 12:05:29:940PM	1110215010	Dennis Whyte	Reverse B 0.8 MA, lower delta ~0.5 Decreased ICRf H-mode at 1.1 seconds at 2.7 MW Is this I-mode at ~0.8-0.9 s? I think so H98 ~ 1, Te pedestal clearly formed No clear sign of WCM, but 88 GHz reflectometer shows clear reduction in broadband fluctuations. JT says we obtained good IR profiles throughout the shot.
Feb 15 2011 12:39:38:900PM	1110215012	Dennis Whyte	Reverse B 1.0 MA, lower delta ~0.5 Clear I-modes around 0.8 and 1.2 s Interesting (strange) behaviour of the pedestal Te with power (Pnet constant or increasing) yet Te takes several jumps...appears to correlate with WCM on magnetics. No H-mode H98 ~ 1 Got good I-mode heat profiles in divertor Sign on Wide that there is something heating up in the inner divertor. Start adding the neon
Feb 15 2011 01:10:14:697PM	1110215014	Dennis Whyte	Reverse B 1.0 MA, lower delta ~0.5 Very clear I-mode, particularly from 1.35-1.5 s. H98 ~1.2 Probably one of best I-modes in H factors we've ever seen. Clear WCM too
Feb 15 2011 01:24:30:260PM	1110215015	Dennis Whyte	Cryo burps are burning shots. Not clear that cryo is providing much pumping anyway so place in standby
Feb 15 2011 01:40:41:403PM	1110215016	Dennis Whyte	Good steady I-mode through most of the shot No H-mode transition up to 3.15 MW H98 ~ 1.15 Good IR data on this shot Low Prad, no injections I-mode maintained over a wider range of input power (2.2 - 3 MW) than we have ever achieved in previous campaigns. Density starts to increase somewhat at end of flattop (weak particle barrier) This looks like a trophy for analysis.
Feb 15 2011 01:50:34:047PM	1110215017	Dennis Whyte	another very good steady I-mode through most of the shot No H-mode transition up to 3.45 MW H98 ~ 1.2 for much of the flattop Good IR data on this shot Low Prad, on big injection at 0.8 s but the plasma recovered In combo with shot 16 this shows I-mode from 2.2 to 3.45 MW Running out of time looking for H-mode here Going to higher Ip
Feb 15 2011 02:02:59:623PM	1110215018	Dennis Whyte	LSN delta ~ 0.5 Ip =1.25 Early injections + large injection --> disruption Got I-mode at 3 MW, H98~ 1 Tweak up density & neon to counter injections
Feb 15 2011 02:26:36:780PM	1110215020	Dennis Whyte	LSN delta ~ 0.5 Ip =1.25 Early disruption Next: delay power input to account for later flattop in Ip
Feb 15 2011 02:58:50:540PM	1110215021	Dennis Whyte	Good I-modes from 0.8 to end of flattop. Several injections but recovered. No H-mode up to 3.6 MW again the power window for I-mode seems much larger at this triangularity WCM has varying characteristic throughout affected by small density changes and injections.
Feb 15 2011 03:27:28:647PM	1110215023	Dennis Whyte	Good I-modes at 1.25 MA, Best I-mode phase ~ 1.2-1.3 s Did not get H-mode Just a few smaller injections, so higher NL04 and neon worked well. Very clear I-L transition at 1.05 seconds. The Te_ped ratchets up with each sawtooth pulse Should provide very good analysis for fluctuations and pedestal
Feb 15 2011 03:51:04:750PM	1110215024	Dennis Whyte	Back to 1 MA for shape scan. Early disruption
Feb 15 2011 04:25:45:857PM	1110215027	Dennis Whyte	continuing to get early injection with this smaller lower delta. I'm worried that moving the strikepoint up onto the nose has decreased our power handling capability PUnting on this triangularity and trying to get some higher triangularity.
Feb 15 2011 04:43:38:640PM	1110215028	Dennis Whyte	LSN, 1 MA, lower delta = 0.6 Moved the OSP into the slot. A stunning change compared to delta=0.5 (shot 17). Same density, same power, same Pnet, yet no sign of I-mode in this shot. pedestal T stays constant, and stored energy ~100 kJ (compared to 140-150 kJ in shot 17) just from that small change in triangularity/OSP position.
Feb 15 2011 05:07:17:937PM	1110215029	Dennis Whyte	LSN, 1 MA, lower delta = 0.7 No sign of I-mode Early disruption. Probably caused by touching power onto the inner nose.
Feb 15 2011 05:17:40:770PM	1110215031	Dennis Whyte	LSN, 1 MA, back to lower delta ~ 0.5 and increase the upper triangularity Successfully recovered I-mode performance close to shot 17
