Session Leader Plan for 1080429 AM Session Leader: G. Wallace Physics Operator: S. Wolfe This run will be in support of MP551, "Penetration of Accessible LH Waves." We will be investigating the drop-off of HXR emission as the line integrated density rises above ~6e19. This will be a repeat of 1080424 without the disruptions. LH Setup: Launcher 1.0mm behind limiter, 75 and 105 degree approximate phasing, current drive direction, 600kW net power, LH on from 0.7-1.2s. Starting Shot: 1080408020 Shot Plan: 1. Bring up LH power to 600kW at 75 degree phasing with nl_04 steady at 4e19, 5.4T, 800kA. (2 shots) 2. Scan density from 3e19 (or as low as possible without locked modes) to 6e19 nl_04 between 0.7 and 1.2 seconds at 5.4 T, 800kA, 75 degrees. Cryopump and/or inner wall puffing may be required for density control. Repeat at 105 degrees. (2 shots) 3. Scan density from 5e19 to 1e20 nl_04 between 0.7 and 1.2 seconds at 5.4 T, 800kA, 75 degrees. Cryopump and/or inner wall puffing may be required for density control. Repeat at 105 degrees. (2 shots) 4. Repeat 2 and 3 at 6.2T, 800kA. (4 shots) At this point we will switch to MP541. Steps 5-8 may be attemped later in the day or on another day as time permits. 5. Repeat 2 and 3 at 5.4T, 800kA, 900kW. (4 shots) 6. Repeat 2 and 3 at 5.4T, 1.1MA. (4 shots) 7. Repeat 2 and 3 at 5.4T, 500kA. (4 shots) 8. Repeat 2 and 3 at 5.0T, 800kA. (4 shots) Total of 26 shots.

Session Leader Summary for 1080429 Session Leader: G. Wallace Physics Operator: J. Snipes MP551: Penetration of Accessible LH Waves, Shots 1-18 The tokamak started up nicely and ran clean discharges all morning after removing the ASP from it's position inside the plasma. Good density scans were obtained at 75 and 90 degree phasing with toriodal fields of 5.4 and 6.0T. Due to time constraints, only the low-end density scans (nl_04=3.3-6e19, nebar=5.5-10e19) were obtained on this day, and no current scan was performed. The cyropump ran well on this day, however we were unable to start the density scans quite as low as we had hoped for (nl_04=3e19) due to the amount of recycling from the walls and also the now familiar low density MHD activity. At first glance, the HXR emission as a function of density looks remarkably like a straight line with a negative slope (i.e. HXR_countrate = -A*nebar + B), although closer inspection shows that there is a knee in the curve in each shot around nebar=6.5e19. This is where the slope was observed to change from something proportional to 1/n to a steeper slope in previous experiments. As hoped, a scan from high to low density resulted in data which overlaid almost exactly on a scan from low to high density. A power scan with shots at 500kW and 800kW resulted in data consistent with the other scans at 700kW. Unfortunately the change to higher field did not increase the HXR count rate for any density at either phasing. Data from the day show remarkably little variation across different values of launched n|| and toroidal field when normalized to the square root of net LH power. MP541: LH wave damping with plasma temperature, shots 19-29 An ICRF power scan from 1MW to 4MW (counter-current MCCD) was conducted at 75 and 90 degree LH phasing. Te0 of up to 5keV with the LH on was obtained on shot 22. Some difficulty was encountered in obtaining shots in which both the ICRF and the LHCD systems stayed on at the same time, although most shots had at least 100ms of overlap between the two, which gives enough to to determine the profile of HXR emission. Preliminary analysis indicates a wider HXR emission profile at the higher temperatures.

The machine ran very well today despite a slow start due to a faulty UPS for the power room. There were two test shots at the beginning of the run for the data system and for EF4 to test changes in dpcs. Then, there were 27 plasmas in a row with no fizzles and no duds. Even though the cryopump seemed to fail to pump at the beginning of at least two shots and the neutral pressure exceeded 0.09 mTorr, the plasmas still went fine. There was one disruption in the flattop and one early in the rampdown and one at the end of the current rise with up to 4 MW of ICRF and up to 0.8 MW of LHCD. All of the other plasmas ramped all the way down. Very interesting results were obtained from the first half of the run where the density dependence of the LHCD efficiency was mapped out. The last part of the run was not as good in that the combined LHCD+ICRF often led to trips of one or both systems. Still for the times when both systems were running, there is good data across a range of phasing and heating power. Overall, there were 29 shots, 27 plasmas, 0 fizzles, 0 duds, and 2 test shots.

Session Leader Comments
Apr 29 2008 07:57:20:673AM	1080429001	Greg Wallace	Starting with conditions from 1080424003 for LH system.
Apr 29 2008 09:43:36:613AM	1080429003	Greg Wallace	Great shot! Plasma until rampdown, clean LH pulse. Will move on to density ramp at 75 degree phasing.
Apr 29 2008 10:11:50:637AM	1080429004	Greg Wallace	Clean shot. Density ramp looked great, 3.6-5.8e19 on nl_04. Will repeat at 105 phasing with 80ms of argon puffing.
Apr 29 2008 10:20:06:407AM	1080429005	Greg Wallace	Early trips caused by 6T. Will switch to 90 degree phasing where we have usually have more luck as the second phase.
Apr 29 2008 10:37:08:857AM	1080429006	Greg Wallace	Clean shot at 90 degrees, density ramp from 3.8-6e19. Looking back at processed HXR data from shot 4, seems like we started the density ramp quite close to the edge of the drop in HXR emission. Will go back and repeat the low density ramp at 75 and 90 degrees, delaying the ramp until .75s and requesting a bit lower density before the LH comes on.
Apr 29 2008 10:49:02:570AM	1080429007	Greg Wallace	Clean shot, but density is still 3.7e19 at .75s. Will try one more time to go lower in density by programming lower and turning off the argon.
Apr 29 2008 11:23:43:020AM	1080429008	Greg Wallace	Arcing in 23 bottom waveguides. Will turn down power on klystron 12 to 100kW.
Apr 29 2008 11:35:55:027AM	1080429009	Greg Wallace	Clean shot, got the density scan we wanted at 75 degrees. Moving on to same shot at 90 degrees.
Apr 29 2008 11:52:02:493AM	1080429010	Greg Wallace	Clean shot at 90 degrees, got the density ramp we want. Will move on to 6.2T at 75 degrees.
Apr 29 2008 12:07:26:270PM	1080429011	Greg Wallace	Clean shot at 75 degrees, 6.0T. Moving on to 90 degrees at 6.0T.
Apr 29 2008 12:28:59:913PM	1080429012	Greg Wallace	Locked mode? LH ran clean but Ip takes a dive around .85s. Will repeat to see if we can avoid the locked mode.
Apr 29 2008 12:46:53:943PM	1080429013	Greg Wallace	One trip late in the shot, but otherwise clean at 90 degrees. No sign of locked mode. Going back to 75 degrees, but ramping density down instead of up.
Apr 29 2008 01:00:15:377PM	1080429014	Greg Wallace	Density ramp didn't go quite as low as I would have liked and one trip early but otherwise clean. Will retry with ramp starting at a lower density.
Apr 29 2008 01:16:32:683PM	1080429015	Greg Wallace	Density scan goes deeper, still not quite as low as we wanted, but moving on to higher power at 5.4T with the rising density.
Apr 29 2008 01:30:35:180PM	1080429016	Greg Wallace	17T caused one trip early in the pulse. Will increase the power for klystron 9 to 110kW and try again.
Apr 29 2008 01:39:25:320PM	1080429017	Greg Wallace	One trip early, but otherwise clean. Will try next shot at ~450kW, then go on to the PM run.
Apr 29 2008 01:59:15:270PM	1080429018	Greg Wallace	Clean shot around 500kW. Next shot will move on to MP541. LH will fire at 0.15s, 500kW.
Apr 29 2008 02:19:56:270PM	1080429019	Greg Wallace	Many trips. ICRF doesn't seem to be helping with the coupling. Will try turning up klystron 9 a little to see if that helps with the high reflections on that channel. Going up to 2MW ICRF.
Apr 29 2008 02:29:40:140PM	1080429020	Greg Wallace	Some overlap of LH and ICRH. Moving on to 3MW from J.
Apr 29 2008 02:44:54:337PM	1080429021	Greg Wallace	Sustained LH + ICRF after .43s. Next shot will move on to 4MW ICRH.
Apr 29 2008 03:07:25:167PM	1080429022	Greg Wallace	Te around 4keV from .45-.65s with LH on. Will try changing the He3 puff for next shot.
Apr 29 2008 03:33:33:517PM	1080429023	Greg Wallace	First few trips 23bottom, later trips 17bottom. Nice hot plasma, though. Going on to 120 degrees.
Apr 29 2008 03:38:38:130PM	1080429024	Greg Wallace	120 doesn't look like it's going to work. Trying 105 phasing on next shot.
Apr 29 2008 03:58:24:847PM	1080429025	Greg Wallace	Nothing but trips on the LH again, even at 105 phasing. Will attempt to increase the plasma density a bit to see if that helps.
Apr 29 2008 04:17:26:020PM	1080429026	Greg Wallace	Shot looked much better with a little more density. Two sustained periods of LH with Te~3keV. Moving on to 3MW ICRF from J.
Apr 29 2008 04:34:02:170PM	1080429027	Greg Wallace	Poor coupling caused many trips. Will try raising the density and keeping ICRF at 3MW.
Apr 29 2008 04:51:34:060PM	1080429028	Greg Wallace	LH clean after trip at initial turn on. Next shot will go to 4MW and 1.2MA to try to increase the temperature as much as possible.
Apr 29 2008 05:16:15:970PM	1080429029	Greg Wallace	Last shot of the day. Disruption at .55s. LH on rom .25 to .55s. ICRF tripped at .25s so Te never made it up very high.

Physics Operator Comments
Apr 29 2008 08:09:28:980AM		Joseph Snipes	It seems there is a problem with the backup UPS power supply for the power room. If it cannot be fixed soon we may delay or cancel the run depending on Jim Irby's decree.
Apr 29 2008 08:51:55:403AM	1080429001	Joseph Snipes	Shot 1: Test shot to test the data system.
Apr 29 2008 09:02:12:190AM	1080429002	Joseph Snipes	Shot 2: EF4 test shot.
Apr 29 2008 09:40:11:330AM	1080429003	Joseph Snipes	Shot 3: Loaded shot 1080424003, which uses segment 3 as the main segment and has a SNU plasma at 0.8 MA, 5.4 T, with nl04 = 4 x 10^19 m^-3. Increased prepuff to 54 ms duration. Good shot!
Apr 29 2008 09:57:58:250AM	1080429004	Joseph Snipes	Shot 4: Changed nl04 programming to ramp down to 3 x 10^19 m^-2 at 0.6 s and then begin ramping up at 0.7 s and reach 6 x 10^19 m^-2 by 1.2 s and then begin ramping the density down at 1.3 s to zero by 1.5 s. Good shot.
Apr 29 2008 10:12:19:200AM	1080429005	Joseph Snipes	Shot 5: Repeat with argon puff from 0.3 to 0.38 s. Good shot except the LH tripped.
Apr 29 2008 10:26:59:257AM	1080429006	Joseph Snipes	Shot 6: Increased prepuff by 2 ms to 56 ms duration. Good shot.
Apr 29 2008 10:58:43:187AM	1080429007	Joseph Snipes	Brief delay to inspect EF4 power supply due to an I^2t limit that is not resetting.
Apr 29 2008 11:01:53:487AM	1080429007	Joseph Snipes	Shot 7: Reloaded shot 5 and changed nl04 to start a ramp at 2.8 x 10^19 m^-2 at 0.75 s and ramp up to 6 x 10^19 m^-2 at 1.2 s. Good shot. The cryopump apparently burped and doubled the pressure at breakdown to nearly 0.13 mTorr and yet miraculously we still got breakdown and a decent current rise!
Apr 29 2008 11:21:14:877AM	1080429008	Joseph Snipes	Shot 8: Disabled argon puff and changed nl04 to start a ramp at 2.2 x 10^19 m^-2 at 0.75 s and ramp up to 6 x 10^19 m^-2 at 1.2 s. Extended PG3 to 0.14 s at 65 V to avoid early runaways. Good shot but LH tripped.
Apr 29 2008 11:34:08:700AM	1080429009	Joseph Snipes	Shot 9: Repeat without LH trips. Good shot.
Apr 29 2008 11:59:58:250AM	1080429010	Joseph Snipes	Shot 10: Increased PG3 gas from 0.02 to 0.1 s in segment 1 to try to eliminate the early runaways. Good shot.
Apr 29 2008 12:15:43:573PM	1080429011	Joseph Snipes	Shot 11: Raised TF current to 172 kA to go to 6.2 T until 1.25 s. Slightly changed the Ip rampdown as well. Good shot but the TF did not reach 6.2 T because the current limit is set to 165 kA. We'll stick with this TF to avoid having to repeat this shot.
Apr 29 2008 12:29:33:867PM	1080429012	Joseph Snipes	Shot 12: Repeat at 90 degree phasing. Nearly locked mode (QSM quasi-stationary mode) from 0.85 - 0.99 s visible on the fast magnetic pick-up coils. Otherwise a good shot.
Apr 29 2008 12:38:59:153PM	1080429013	Joseph Snipes	Shot 13: Repeat without the QSM. Good shot without the QSM.
Apr 29 2008 12:55:58:543PM	1080429014	Joseph Snipes	Shot 14: Return to 150 kA TF current in segments 1 and 3. Set nl04 to 5 x 10^19 m^-2 until 0.75 s then negative to turn off the gas and ramp down the density during the LHCD. Good shot.
Apr 29 2008 01:14:14:993PM	1080429015	Joseph Snipes	Shot 15: Reduced nl04 to 4 x 10^19 m^-2 and turn it off at 0.7 s. Good shot.
Apr 29 2008 01:33:20:633PM	1080429016	Joseph Snipes	Shot 16: Reloaded shot 9 and then reloaded segment 1 from shot 15. Good shot.
Apr 29 2008 01:40:17:940PM	1080429017	Joseph Snipes	Shot 17: Repeat with higher LHCD power. Good shot. The ratiomatic is again showing very high neutral pressure at breakdown above 0.09 mTorr. Apparently, the cryopump is not pumping as it should. It is surprising that we get a decent current rise at this high pressure.
Apr 29 2008 02:05:25:510PM	1080429018	Joseph Snipes	Shot 18: Repeat with higher LHCD power and with some ICRF after 1.2 s. Good shot.
Apr 29 2008 02:16:48:347PM	1080429019	Joseph Snipes	Shot 19: Now going to the ICRF+LHCD part of the day for MP541. Loaded segment 3 from shot 3 into segment 3 and changed PG2 in both segments 1 and 3 to have a 100 V He3 gas puff from 0.02 to 0.22 s. ICRF from 0.1 s to 0.6 s and LHCD from 0.15 s to 0.65 s. Both RF systems tripped but were on for some of the time. Otherwise it is a good shot.
Apr 29 2008 02:32:27:907PM	1080429020	Joseph Snipes	Shot 20: Repeat to try to keep the RF from tripping. Good shot but the RF still tripped.
Apr 29 2008 02:44:08:993PM	1080429021	Joseph Snipes	Shot 21: Repeat. Good shot.
Apr 29 2008 02:57:25:643PM	1080429022	Joseph Snipes	Shot 22: Repeat. Good shot.
Apr 29 2008 03:14:55:300PM	1080429023	Joseph Snipes	Shot 23: Reduced He3 puff to end at 0.15 s. Good shot.
Apr 29 2008 03:33:20:563PM	1080429024	Joseph Snipes	Shot 24: Returned He3 puff to end at 0.22 s. Good shot.
Apr 29 2008 03:52:58:983PM	1080429025	Joseph Snipes	Shot 25: Enabled argon gas and programmed the puff from 0.2 to 0.3 s. Turned off dpcs_ftae2, which has been on all day but is not being used. Disrupted at 1.65 s. Hard x rays from 0.03 s until 1 s. Lots of runaways.
Apr 29 2008 04:19:46:503PM	1080429026	Joseph Snipes	Shot 26: Increased argon to 140 ms duration out to 0.34 s. Increased prepuff by 5 ms to 61 ms duration. Increased PG3 in both segments 1 and 3 from 0.011 s through 0.28 s. Disrupted at 1.15 s. Mode clearly locks at 0.38 s on the fast magnetics data.
Apr 29 2008 04:29:00:713PM	1080429027	Joseph Snipes	Shot 27: Raised nl04 to 6 x 10^19 m^-2 after 0.7 s. Granetz says there is some serious problem with the DNB but he is unable to tell exactly what the problem is without going into the cell. Disabled the DNB gate valve. Much better shot but the LHCD tripped early.
Apr 29 2008 04:50:29:027PM	1080429028	Joseph Snipes	Shot 28: Increased nl04 to 6 x 10^19 m^-2 from 0.28 s until 1.5 s. Good shot.
Apr 29 2008 05:09:00:463PM	1080429029	Joseph Snipes	Shot 29: Increased Ip to 1.2 MA to reach flattop by 0.56 s. Disrupted at 0.55 s.
