Session leader summary for 1101105 Session Leader: G. Wallace Physics Operator: R. Parker Miniproposal: 605 LH2 Lower Hybrid Launcher Checkout and Conditioning The purpose of today's run was to assess the performance of the LH launcher after implementing the multijunction-like modification to the magic-T power splitters. The modification involved removing the dummy load on the 4th port of each magic-T and replacing it with a short. The power splitting on klystron 10 was very uneven with the original location of the short. The forward power in column 16 was very low and as a result the reflection coefficient was >> 100%. A ~1/4 wavelength shim was added between the magic-T and the short. Following this change the power splitting was much better and col 16 did not cause any more problems for the rest of the day. Reflection coefficients were very high (~100%) on many columns for phases of 105 deg and above. 75 and 90 deg phases had low reflection coefficients and few nuisance trips. Scans of ZCUR and the outer gap showed that the launcher behavior has not changed substantially with the MJ-like modification. Power is still distributed between rows of the launcher as the plasma moves. Power was increased up to 180 kW/klystron at 75 deg phasing. Net power with the modified magic-T's was 10-15% higher than for the unmodified system (with the same klystron power and reflection coefficient). Overall reflection coefficient is about the same as before the modification. The increase in net LH power comes from the recirculation of the reflected power. The launched n|| spectrum does not appear to be adversely effected by the recirculation of the reflected power. A Fourier transform of the forward power at the waveguide mouths is very similar to the unmodified spectrum with the exception of some small shifts in the side lobes. The current drive efficiency seemed to be as expected based on changes in loop voltage.

A relatively easy day for the PO, with few changes in plasma conditions. There were two delays for a total of 3 hours, caused by troubleshooting problems with the lower hybrid system. The first was between shots 1 and 2 (2.5 hours), the second between shots 4 and 5 (0.5 hour). The initial shot was the same as 1101019031. During the early part of the run the triangularity was varied, as was the vertical position (by 4 cm at the X-point) and the right gap (by 2 cm) -- all to optimize LH coupling. Beginning with shot 12 the equilibrium was fixed with no further variations. Scorecard: 22 plasma attempts, all successful, 1 disruption (caused by too large a jog in the vertical position), and 21 plasmas which ran into rampdown.

Session Leader Comments
Nov 5 2010 09:32:07:093AM	1101105001	Greg Wallace	Result: All trips. First two segments (75 deg) look OK except for col 16 which has very high reflected power. 90 deg segment looks OK except for col 16 as well. 105 deg and higher phasing have very high reflections on many columns. Forward power on IDC for klystron 10 looks very low---only 20 kW? Same thing happened on test shot into dummy load. Sum of forward power on split columns (from JGDC's) is greater than power into magic-T (from IDC). Net power/FINT power is also higher for same reflection coefficient, so the math seems to be correct. We're seeing about 64% of the FINT power making it to the plasma now, as compared to about 56% without the magic-T modification, which is a factor of 1.14 in net power for the same klystron power. Next shot: Increase programmed nl_04 to 4e19.
Nov 5 2010 11:59:37:550AM	1101105002	Greg Wallace	Result: All trips again. Col 16 is the problem at lower phases. Seems like our "unmagical"-T idea does not work on klystron 10. This is not particularly surprising since MJ modification requires that both columns have similar reflection coefficients. We know col 16 has high reflections than 15 by factor of ~2. We might need to put klystron 10 magic-T back the way it was. Next shot: Decrease RXU and RXL by 1cm and 2cm respectively to increase triangularity. This might help redistribute reflected power on col 16?
Nov 5 2010 12:08:44:070PM	1101105003	Greg Wallace	Result: Still all trips on the LH. Col 15 and 16 are not splitting evenly again. Seems like we really can't handle the MJ modification on klystron 10, at least without changing the short location. Next shot will go back to plasma from shot 2 and will put klystron 10 into dummy load. Next shot: Reload shot 2, put klystron 10 into dummy load.
Nov 5 2010 12:50:52:240PM	1101105004	Greg Wallace	Result: No trips for 75 and 90 deg segments. All higher phasings were only trips. Klystron 7 forward power level drops from 20 kW to 12 kW as phase changes. Next shot: Same plasma. Installing 2cm phase shim between magic-T and short on klystron 10. We hope that by adding ~1/4 wavelength shim between the short and the magic-T that this will move us from a very uneven power split to an even power split between cols 15 and 16. Also troubleshooting problem with klystron 10 drive system during the hour we are in the cell installing the shim.
Nov 5 2010 01:12:20:433PM	1101105005	Greg Wallace	Result: Much better with 1/4 wavelength shim added to magic-T on klystron 10. 75 deg segment had no trips, a few trips in 90 deg segment. 105 and higher phasing segments still all trips. Power splitting on klystron 10 is now a bit uneven but in the other direction (more forward power in 16 than 15) which helps keep reflection coefficient down on col 16. n|| spectrum looks clean based on Orso's probes. Next shot: Move on to step 2 of run plan. Will go to 75 deg phasing and move plasma vertically from -2 cm to +4 cm.
Nov 5 2010 01:18:57:847PM	1101105006	Greg Wallace	Result: Disruption at .65 s. Looks like we made the vertical shift a little too severe and the plasma disrupted when it hit the bottom of the LFS limiter. Next shot: Reduce ZCUR scan by 1 cm on either extreme. New scan will be from -1 cm to +3 cm.
Nov 5 2010 01:33:49:430PM	1101105007	Greg Wallace	Result: No trips at 75 deg. Plasma was able to handle the vertical jog. LH reflection coefficient was not particularly sensitive to change in plasma position. Next shot: Repeat vertical jog at 90 deg phasing.
Nov 5 2010 01:47:06:927PM	1101105008	Greg Wallace	Result: LH ran clean again, this time at 90 deg phasing. Vertical jog did not adversely effect reflection coefficient. Refco remained around 30% throughout the pulse. 229 kW net power out of 378 kW FINT total with refco of 30%. Next shot: Back to 75 deg phasing. Reload shot 5. Outer gap scan from 0.5 to 3.0 cm during LH.
Nov 5 2010 01:59:03:273PM	1101105009	Greg Wallace	Result: Outer gap scan from 0.8 cm to 2.75 cm. No LH trips at 75 deg phasing. Reflection coefficient dropped throughout shot as gap increased. Next shot: Decrease initial gap to 0.5 cm and increase final gap to 3 cm. Stay at 75 deg.
Nov 5 2010 02:11:28:123PM	1101105010	Greg Wallace	Result: Got wider range of outer gap. A few trips at the end of the LH pulse when outer gap is 3cm. Overall transmission efficiency (net power / FINT power) is 64% compared with mid 50's% without modification. Next shot: Same plasma, 90 deg phasing.
Nov 5 2010 02:29:43:670PM	1101105011	Greg Wallace	Result: Many trips in later part of discharge (large outer gap). Reflection coefficient steady around 30%. Overall efficiency of ~62%. Without MJ modification this would be ~53%. Next shot: Steady outer gap of 2cm. 75 deg phasing. Increase power to 80 kW/klystron.
Nov 5 2010 02:43:13:097PM	1101105012	Greg Wallace	Result: Clean LH pulse at 80 kW/klystron. 430 kW net power and 650 kW FINT power = 68%. Approx 15% higher net power for same klystron power as compared to old setup (assuming 22% reflected power). Next shot: Increase to 130 kW/klystron. Stay at 75 deg.
Nov 5 2010 03:00:49:200PM	1101105013	Greg Wallace	Result: Clean LH pulse at 130 kW/klystron. Significant current drive, Vloop reduced to ~0.35 V. 725 kW net power out of 1050 kW FINT power or 69%. Again, 15% more net power than old configuration for same klystron power and refco. Next shot: Increase to 150 kW/klystron on all except for #10.
Nov 5 2010 03:10:45:153PM	1101105014	Greg Wallace	Result: Clean LH pulse at 150 kW/klystron. 800 kW net out of 1225 kW FINT = 65% net power with 20% reflected. ~10% more net power than without MJ modification. Next shot: Increase to 170 kW/klystron.
Nov 5 2010 03:27:02:087PM	1101105015	Greg Wallace	Result: Many trips in second half of pulse. Looks like klystron 2 wasn't restriking properly. Next shot: Decrease to 150 kW/klystron, try again.
Nov 5 2010 03:37:43:830PM	1101105016	Greg Wallace	Result: Circulator 2 arc fault. No successful restrikes after klystron 2 was shut off by TPS. Next shot: Repeat.
Nov 5 2010 03:54:31:457PM	1101105017	Greg Wallace	Result: Clean LH pulse at 150 kW/klystron. Net power 800 kW out of FINT power of 1200 = 67% with refco of 24%, 15% more than before modification. Next shot: Increase LH power to 160 kW/klystron.
Nov 5 2010 04:07:17:110PM	1101105018	Greg Wallace	Result: Clean LH at 160 kW/klystron. 870 kW net for 1280 kW on FINTs = 68% with 20% reflected power. Next shot: Go back up to 170 kW/klystron.
Nov 5 2010 04:23:47:540PM	1101105019	Greg Wallace	Result: One restrike at 0.9 s. Might be due to 14T. 910 kW net, 1375 kW on FINTs, 66% to plasma at 20% refco. Next shot: Increase to 180 kW/klystron.
Nov 5 2010 04:43:19:703PM	1101105020	Greg Wallace	Result: Looks like we've hit the power limit for the magic-T on klystron 2. Next shot: Scan from 60 to 90 deg phasing at 160 kW/klystron for Roman.
Nov 5 2010 04:51:07:063PM	1101105021	Greg Wallace	Result: Lots of trips but some segments without trips. Looks like more activity in the klystron 2 magic-T? Next shot: Going down in power to get a clean shot.
Nov 5 2010 05:03:04:383PM	1101105022	Greg Wallace	Result: All trips. Last shot of the day.

Physics Operator Comments
Nov 5 2010 09:16:59:027AM	1101105001	Ron Parker	First shot ran OK, disrupting about halfway into rampdown. LH tripped repeatedly
Nov 5 2010 09:19:42:920AM	1101105001	Ron Parker	We're holding while LH figures out why klystron 10 produced less than 1/2 of requested power.
Nov 5 2010 11:45:38:847AM	1101105002	Ron Parker	Finally, after trouble shooting problem with LH, shot 2 ran essentially full length, but LH continues to fault.
Nov 5 2010 11:59:22:653AM	1101105003	Ron Parker	For next shot, we are going to try to increase triangularity by moving the lower X-point in 2 cm, and 1 cm on the upper.
Nov 5 2010 12:07:05:547PM	1101105003	Ron Parker	The plasma shot was fine, higher X-point triangularity, but LH still faulting. Next: Repeat shot 2
Nov 5 2010 12:18:59:513PM	1101105004	Ron Parker	Shot 4 ran well, LH survived during the 75 and 90 deg phasing, but faulted for the others. Next: There will be a cell access, expected to last ~ 1 hour Mahlzeit!
Nov 5 2010 01:12:25:623PM	1101105005	Ron Parker	Shots have resumed, shot 5 ran essentially full length (down to ~ 165 kA)
Nov 5 2010 01:21:15:987PM	1101105006	Ron Parker	Shot 6 disrupted, we moved the plasma too far down, and it became limited about 45 deg from horizontal in the radial direction. Next: We'll take + and - 1 cm off programmed vertical displacement.
Nov 5 2010 01:51:26:050PM	1101105007	Ron Parker	Shot 7 ran full length, with vertical sweep
Nov 5 2010 01:51:57:937PM	1101105008	Ron Parker	Shot 8 ran full length, no plasma changes from shot 7.
Nov 5 2010 01:56:18:547PM	1101105009	Ron Parker	For shot 9, we are scanning outer gap, starting at 0.5 cm and ending at 3 cm. Shot ran as programmed, although the right gap scanned from 0.8 to 2.8 cm.
Nov 5 2010 01:59:43:130PM	1101105009	Ron Parker	Next, as in shot 9 but add + and - 3 mm to gap scan
Nov 5 2010 02:12:58:307PM	1101105010	Ron Parker	Shot 10 ran full length. Next: Same plasma shot.
Nov 5 2010 02:32:33:243PM	1101105011	Ron Parker	Shot 11 ran full length (to 200 kA in rampdown) Next: +2 cm right gap seems to be optimum for coupling at 75 deg, so we'll fix it there for the next shot.
Nov 5 2010 02:52:57:733PM	1101105012	Ron Parker	Shot 12 ran full length, similar to others in this run LH power slightly over 400 kW
Nov 5 2010 02:56:06:633PM	1101105013	Ron Parker	Shot 13 ran full length, LH power broought up to 675 kW Loop voltage touches 0 early during LH pulse, but relaxes to aboout 0.4 V
Nov 5 2010 03:14:54:730PM	1101105014	Ron Parker	Shot 14 ran full length, LH power up to 800 kW
Nov 5 2010 03:22:24:607PM	1101105015	Ron Parker	Shot 15 ran OK, but LH tripped early and didn't recover.
Nov 5 2010 03:37:25:450PM	1101105016	Ron Parker	Shot ran OK, but Klystron 2 circulator arced, and LH tripped early.
Nov 5 2010 03:57:23:033PM	1101105017	Ron Parker	Shot 17 ran essentially full length, LH ran through at 800 kW.
Nov 5 2010 04:35:12:763PM	1101105018	Ron Parker	Shot 18 ran full length. No changes for next shot.
Nov 5 2010 04:35:28:527PM	1101105019	Ron Parker	Shot 19 ran full length. No changes for next shot.
Nov 5 2010 04:36:14:313PM	1101105020	Ron Parker	Shot 20 ran full length.
Nov 5 2010 05:01:45:173PM	1101105021	Ron Parker	Shot 21 ran into rampdown
