Session Leader Plan for 1101019

MP:463 Reaching zero loop voltage with LHCD

Session Leader: R. Parker
Physop: G. Wallace

As the name of the MP implies, the objective is to reach zero loop voltage with lower hybrid current drive. Unlike previous attempts, this one will try to reach zero voltage at low, rather than high current. This should help in at least two respects: i) lower density should be achievable, which helps current drive efficiency, and ii) lower current means that lower values of P/n should be sufficient to drive full current.

Important diagnostics for this run, in addition to the "standard" LH diagnostics, will be HIREX: in which direction and with what speed will be the rotation; impurity injection: how does impurity transport change with low or zero loop voltage; and MSE: what will be the current distribution and how does it compare with LHEAF modeling?

Run Plan

Shots 1-5: Prepare Ohmic target.

Use equilibrium from 1101015028, but program density for nl_04~ 3-4 m-2 (or lower), Current = 500 kA, TF = 5.4 T, Flattop = 1.6-1.7 s. If there is trouble achieving this target, load shot 1100217001

Shots 6-10: Bring up LH power to "comfortable" level. Adjust grill position, outer gap for good coupling at 90 deg phasing.

Shots 11-15: If V_loop ~ 0 V, Collect MSE, HIREX and impurity confinement data

If V_loop is not zero, continue tuning discharge in shots 11-15 toward lower density and current. Assuming V_loop ~ 0, shots 16-20 used as above for data collection.

Shots 16-25: If there is power margin, do scan of density, current, power relation to keep V_loop ~0.

A very good run for LH. By lowering the current, running upper null with the cryo to control the density, and optimizing the coupling with launcher position and outer gap, it was possible to produce several discharges with zero loop voltage. Good examples are shots 14 and 31. These shots can be used to unequivably infer the current drive efficiency, at least at n_par ~ 1.6 and T_e(0) in the range 3-4 keV. Good data, at least for shot 14 was obtained for MSE; this should allow a comparison with LHEAF simulations. A surprise was that the LH-induced rotation was persistently co rather than counter as expected from earlier rotation studies, although there seems to be conflicitng data from HIREX Sr and Jr.This will require an evaluation of the spatial distribution of the charge states looked at by the two instruments.

A very good run day for LH today. Several current drive trophy shots at 500 kA plasma current and low density (nl_04~3e19). Trophy shots had V_loop~0 for 0.5 s. n*I*R/P ~ 1.5-1.8e19 for the full current drive shots at n_||=1.6.

In addition to good current drive performance, the LH2 coupler achieved a steady power level of 1.0 MW for the first time, with a peak power of 1.1 MW. No injections or flashing on the LH grill face at this power level. The center 4 columns were run up to 148 kW/klystron with split columns at 185 kW/klystron. Net LH power level of 1.0 MW corresponds to a power density of 37 MW/m^2. Outer gap of ~1.5 cm gave the best LH wave coupling results. Launcher location was 0.1-0.2 mm behind limiter for the better part of the day.

Early problems with W injections during LH were solved by decreasing RXL (see difference between shots 12 and 13). This pulled the flux surfaces away from the lower divertor shelf and eliminated the W source. This will be a good trick to remember for future USN runs with high power LHCD.

Scorecard:
Plasmas: 29
Fizzles: 3
Disruptions: 3
Test cycles: 1
Total shot cycles: 33

Session Leader Comments
Oct 19 2010 08:57:25:637AM	1101019001	Ron Parker	First shot was a test of the gas valve. It was OK.
Oct 19 2010 09:29:47:890AM	1101019002	Ron Parker	Shot 2 fizzled, too much fill gas.
Oct 19 2010 10:12:48:597AM	1101019003	Ron Parker	Shot 3 ran OK,I ~ 500 kA, nl_04 ~ 3 e19 m-2. Next: Turn on LH @ 400 kW. But density at grill may be too low.
Oct 19 2010 10:13:16:190AM	1101019004	Ron Parker	Shot 4 looked promissing, LH broought v_loop to ~ 0.25 V with about 630 kW of forward power, 300 kW of net LH power. Next: Moved launcher to 0.1 mm behind limiter.
Oct 19 2010 10:13:47:727AM	1101019005	Ron Parker	Shot 5 fizzled
Oct 19 2010 10:41:38:823AM	1101019006	Ron Parker	Shot 6 ran OK, v_loop still around .3 V. Next: close right gap 1.0 cm to improve coupling.
Oct 19 2010 10:54:51:033AM	1101019007	Ron Parker	Shot 7 was a good LH shot. Next: Increase LH power to ~ 500 kW.
Oct 19 2010 10:57:56:807AM	1101019008	Ron Parker	Shot 8 ran well, good LH shot, v_loop < 0.2 V. Sawtooth stabilized. Next: Increase LH power to ~ 700 kW
Oct 19 2010 11:21:37:883AM	1101019009	Ron Parker	Good LH shot. Need a bit more power.
Oct 19 2010 11:20:47:560AM	1101019010	Ron Parker	We are getting there, v_loop ~ 0 for 100 ms, current rises during LH pulse.
Oct 19 2010 11:36:06:130AM	1101019011	Ron Parker	Shot 11 disrupted shortly after LH turned on. v_loop went positive by ~0.2 V.
Oct 19 2010 12:16:01:473PM	1101019012	Ron Parker	Shot 12 disrupted again shortly after LH turned on
Oct 19 2010 12:16:54:097PM	1101019013	Ron Parker	Shot 13 was the best yet, v_loop ~ 0 for 150 ms.
Oct 19 2010 12:21:42:740PM	1101019014	Ron Parker	A new trophy shot! v_loop = 0, 75 deg phasing for ~ 400 ms
Oct 19 2010 12:42:37:577PM	1101019015	Ron Parker	Another good shot, not quite as good as shot 14. Nathan fired two impurity injections into the LH driven phase with zero loop voltage. Next: repeat, also try to tune gap so that density stays aroound 1.e18 at the grill.
Oct 19 2010 01:39:26:430PM	1101019016	Ron Parker	Repeat of 15
Oct 19 2010 01:38:06:840PM	1101019017	Ron Parker	Repeat of 16
Oct 19 2010 01:39:48:987PM	1101019018	Ron Parker	Repeat of 17
Oct 19 2010 02:01:49:520PM	1101019019	Ron Parker	Shot 19 was programmed for higher power. LH ran full length
Oct 19 2010 02:03:08:603PM	1101019020	Ron Parker	Power was increased again for shot 20. It ran with one LH trip Net power was ~ 1 MW
Oct 19 2010 02:12:44:363PM	1101019021	Ron Parker	LH tripped early, didn't recover.
Nov 16 2010 04:55:46:140PM	1101019022	Ron Parker	More LH power trips
Nov 16 2010 04:54:53:963PM	1101019023	Ron Parker	LH still tripping, asking for too much power. Backoff for next shot
Nov 16 2010 04:53:43:087PM	1101019024	Ron Parker	Good shot, no LH trips, ~ 700 kW Next: increase power to 850 kW
Nov 16 2010 04:52:54:457PM	1101019025	Ron Parker	Shot fizzled, problem with gas/pumping
Nov 16 2010 04:52:00:880PM	1101019026	Ron Parker	A good LH shot, P_LH ~ 800 kW, v_loop ~ 0 Next: An Ohmic shot for MSE.
Nov 16 2010 04:01:39:170PM	1101019027	Ron Parker	Ohmic shot ran full length. Next: Increase LH power to 108 kW in center four columns, split column klystrons at 180 kW.
Nov 16 2010 03:59:37:170PM	1101019028	Ron Parker	Density went up slightly, v_loop slightly negative during most of shot, peak LH power = 1 MW. Next: 180 kW on splits, 135 kW on center
Nov 16 2010 03:58:14:937PM	1101019029	Ron Parker	Shot 29 ran well, a very good LHCD shot. Next: Increase power to 185 kW on splits, 148 on center
Nov 16 2010 03:57:22:887PM	1101019030	Ron Parker	Shot 30 was a bit ratty, needs some conditioning?
Nov 16 2010 03:56:19:583PM	1101019031	Ron Parker	Another pseudo-trophy shot. 1 MW full current drive. Next: Raise density to nl_04 to 4e19 m-2.(Does rotation change?)
Nov 16 2010 03:55:04:237PM	1101019032	Ron Parker	LH tripped early, did not recover. Density was nl_04 ~ 4e19 m-2 as requested. Next: try again with lower power, 170 kW in splits, 85 kW in center

Physics Operator Comments
Oct 19 2010 08:56:23:303AM	1101019001	Greg Wallace	ECDC was turned off overnight and not restarted. 1.5 hours ECDC this morning before the run. Starting shot: 1101015028 Changes: Reduce density during flattop to nl_04= 3.0e19. Reduce Ip to 500 kA in flat top, extended to 1.7 s. Reduce Bt to 5.4 T (150 kA TF bus current), extended to 1.7 s. Import cryo startup into seg 1 from 1101013029. Result: Gas valve test shot. Valves OK.
