Run Plan for 2/29/2008 MP #505c Study of sawteeth in low-density plasmas and associated RSAEs We will be looking for the excitation of q=1 RSAEs during the sawtoothing phase of the plasma discharge. The plasmas we we be looking at are low density and L-mode with moderate to high ICRH power. An upper single null configuration will be attempted to maximize the effectiveness of the cryo-pump for maintaining a steady density. A series of parameter scans in the toroidal field, plasma current, and ICRH power will take the larger portion of the day. If time remains, we will investigate the use of secondary current ramps in the flattop portion of the discharge. Late addition to the MP: the strongest RSAEs were formerly excited prior to the 3rd sawtooth crash. This timing was also very close to the time the plasmas went diverted. I would like to investigate the effects of changes in edge geometry on the core modes by alternating between USN and LSN multiple times throughout the shots. ------------------------------------------ Setup: ECDC and bake at 60C overnight. equilibrium target: 1080103008 ICRF: all transmitter RUN-ON by 8:30am initial power waveform: 1)turn on at 0.20 s 2)ramp to full 2.0 MW by 0.21 s 3)flattop to 0.75 s 4)turn off at 0.75 s LH: no LH required for this run. LH grill should be pulled back as far as possible cryo-pump: yes. diagnostics: 1) PCI at 10 Mhz 2) magnetics at 10 Mhz 3)cNPA set with aperture appropriate for shot similar to 1080222028 4)Neutrons and Hirex to monitor Ti 5)ECE and Thompson (with the option for alternate timing) ------------------------------------------ Shot sequence: *** Prepare Ohmic shot around 10:15am for President Hockfield visit *** Part I - USN vs. LSN comparison 001: start with 1080103008 (USN) (no cryo-pump) 002: repeat using cryo-pump 003: move time of diversion closer to beginning of sawteeth try to get transition to LSN later in shot (around 0.40 s) 004-006: compare RSAE activity from former shots to LSN configuration using shot 1080103011 as target Part II - Bt Scan Using best configuration from prior shots 007-014: Scan from 4.8 T to 6.0 T in 0.15 T steps Part III - ICRF power scans 014-017: Vary power balance from antennas D&E, J only, slow power ramp Part IV - Ip variation 018-021: Flattop values of 600,700,900 and 1000 kA Part V - Secondary Current Ramps 022-024: try for 2 MA/sec ramp rate in flattop, perhaps starting from 600 kA

ICRF on from 0.2 - 0.75 s. The purpose of the run is to investigate sawteeth at low density with ICRF heating to drive reversed shear Alfven eigenmodes near q=1. We will compare USN and LSN magnetic configurations and scan the toroidal field from 4.8 T to 6.0 T in 0.15 T steps. Then, we will choose the best field and do a plasma current scan from 0.6 MA to 1 MA. Finally, we will also do some fast Ip ramps from the flattop phase. See the session leader plan for more details.

MP #505c - Studies of low density sawteeth and assciated RSAEs The run was difficult at first, many disruptions plagued us up until shot 014. Keeping the density above 0.5 (nl_04) seemed to be critical. Additionally, a series of ICRF tests on shots 015-017. The results of these tests showed that J is the likely cause of the high levels of impurities. The remainder of the run was performed without J running with D&E (J was run after D&E shut off, and seemed for the most part fine). A power level of 3.0 MW was maintained through most of the day. The central electron temperatures reached a maximum of about 4 keV, significantly lower than last summer. The RSAE excitation was also not as strong, suggesting that the pressure or pressure gradient terms may be strong modifiers of the RSAE DR. We did not complete the entire Bt scan as outlined, though we covered the range 5.25-5.95T. Maximal excitation occured at 5.7T (compare shots 031 and 032, among others). The current scans showed that lower currents also seemed to be better. This seems at first reckoning to be counter-intuitive as a larger edge q should give rise to a smaller interior volume for these modes and hence larger damping. The higher field is likely showing that the off-axis heating is more effective at generating the fast-ion population. Why the lower current is better will need more consideration. The RF was turned on early in the ramp to get hot plasmas at the beginnning of the sawtoothing phase. A side effect of this was the excitation of some early TAEs, and in shot 026, RSAEs, similar to the 2004 data. This was done at 5.7 T and 600 kA, conditions that we have not looked at in former RSAE studies. ---------------------- total shots: 32 disruptions: 003, 009, 010, 011, 012, 013, 017, 018, 019, 026, 029, 030 system fault: 006 test: 007

It was a pretty good run although we had some difficulty with disruptions at low density and high ICRF power. The machine ran quite well with only one computer glitch on shot 6 just before President Hockfield's visit, which was followed by a no power test shot while she was in the control room. All of the other shots had plasma, except perhaps for shot 1 which only reached 88 kA briefly. The startup was surprisingly robust despite many disruptions. The cryopump ran well. The ICRF ran well, but did lead to disruptions at high power and low density. The data suggest that J port was mainly responsible for the impurity increases that led to the disruptions at low density. When operating above nl04 = 6 x 10^19 m^-2, the disruptions were much less frequent. Alfven cascades in the current rise, TAEs, and q=1 RSAE's associated with sawteeth were all observed on both PCI and sometimes on the magnetic pick-up coils as well. So, despite the large number of disruptions, some quite valuable data on the modes were obtained that will be useful for Eric Edlund's dissertation. There were 32 shots, 29 plasmas, 1 fizzle, 1 computer fault, and one test shot.

Feb 29 2008 09:49:08:593AM	1080229003	Joseph Snipes	Shot 3: Repeat with more ICRF power. Got 3 MW. Disrupted at 0.92 s due to a locked mode.
Feb 29 2008 09:55:47:770AM	1080229004	Joseph Snipes	Shot 4: Turned on the cryopump. Set the prepuff to 50 ms duration. Good shot.
Feb 29 2008 10:07:34:630AM	1080229005	Joseph Snipes	Shot 5: Repeat with higher ICRF power. Good shot.
Feb 29 2008 10:22:51:380AM	1080229006	Joseph Snipes	Shot 6: Repeat with ICRF starting at 0.12 s. Computer system fault. No power.
Feb 29 2008 10:52:41:773AM	1080229007	Joseph Snipes	Shot 7: Turned off dpcs_ftae2, which had been on from the shot I copied. Try a no power test shot. OK.
Feb 29 2008 11:03:42:317AM	1080229008	Joseph Snipes	Shot 8: Run with power. Good shot.
Feb 29 2008 11:21:57:027AM	1080229009	Joseph Snipes	Shot 9: Reduced nl04 to 5 x 10^19 m^-2 and reduced the rise in nl04. Took out the preprogrammed gas in segment 3 from PG3, which was nearly zero anyway. Lowered Ip to 0.75 MA from 0.25 to 0.4 s. Disrupted at 0.4 s
Feb 29 2008 11:40:47:987AM	1080229010	Joseph Snipes	Shot 10: Changed programming on RCUR, CLEARIN, RXL,U, and ZXL,U to divert 0.05 s earlier. Disrupted at 0.688 s due to a locked mode starting at 0.55 s.
Feb 29 2008 11:55:22:317AM	1080229011	Joseph Snipes	Shot 11: Asked the engineering operator to turn the A coils on at 0.2 s rather than 0.3 s as had been copied from 1080103002. Changed TF current to 145 kA in both segments 1 and 3. Disrupted at 0.368 s.
Feb 29 2008 12:16:19:560PM	1080229011	Joseph Snipes	Shot 12: Asked the engineering operator to turn off the A coils. Brief delay for RF data acquisition problems. Disrupted at 0.15 and again at 0.23 s.
Feb 29 2008 12:33:46:127PM	1080229013	Joseph Snipes	Shot 13: Disrupted again at 0.44 s. Turned the A coils on again for shot 14.
Feb 29 2008 12:41:47:820PM	1080229014	Joseph Snipes	Shot 14: Try turning off the RF. Good shot.
Feb 29 2008 12:58:41:123PM	1080229015	Joseph Snipes	Shot 15: Try turning on ICRF antennas each only at 1 MW starting at 0.3 s staggered in time. Reduced proportional gain on the nl04 feedback from 9 to 6 throughout the shot. Disrupted at 0.88 s. It appears that the E port antenna causes some impurity injections and perhaps the J port antenna as well.
Feb 29 2008 01:05:36:867PM	1080229016	Joseph Snipes	Shot 16: Try D and J followed by E port alone. Good shot.
Feb 29 2008 01:23:47:713PM	1080229017	Joseph Snipes	Shot 17: One more RF test shot with combinations of D, E, and J. Disrupted at 1.44 s just after the RF switches off. The radiated power is lower with D+E rather than with J+E or J+D at the same power level.
Feb 29 2008 01:32:42:210PM	1080229018	Joseph Snipes	Shot 18: Return to MP505c with D+E starting at 0.12 s and then add some J at 0.5 s to see if that causes problems or not. Disrupted at 0.568 s after J port comes on indicating that J port is causing the disruptions.
Feb 29 2008 01:45:58:130PM	1080229019	Joseph Snipes	Shot 19: Raised TF current to 153 kA in segments 1 and 3. Disrupted at 0.42 s following a locked mode at 0.367 s.
Feb 29 2008 02:05:52:780PM	1080229020	Joseph Snipes	Shot 20: Raised nl04 to 6 x 10^19 m^-2. Good shot. It seems the low density caused all of the disruption problems (combined with high RF power).
Feb 29 2008 02:22:28:580PM	1080229021	Joseph Snipes	Shot 21: Raised TF current to 157 kA in segments 1 and 3. Good shot.

Feb 29 2008 03:43:30:783PM	1080229026	Joseph Snipes	Shot 26: Reduced Ip to 0.5 MA. Disrupted at 1.33 s. Overshot 0.5 MA to 0.66 MA. Got Alfven cascasdes in the current rise between 0.15 and 0.16 s on the magnetics and PCI.
Feb 29 2008 03:47:44:020PM	1080229027	Joseph Snipes	Shot 27: Increased Ip to 0.9 MA. Good shot.
Feb 29 2008 03:53:55:030PM	1080229028	Joseph Snipes	Shot 28: Eric asked to raise Ip to 0.9 MA by 0.3 s. So, I've programmed that. We'll see if it gets there.
Feb 29 2008 04:02:53:940PM	1080229028	Joseph Snipes	Shot 28: Eric asked to raise Ip to 0.9 MA by 0.3 s. So, I've programmed that. We'll see if it gets there. Reached 0.85 MA by 0.3 s.
Feb 29 2008 04:22:37:960PM	1080229029	Joseph Snipes	Shot 29: Eric asked to raise Ip to really reach 0.9 MA by 0.3 s. So, I've programmed it to go to 0.95 MA at 0.3 s. We'll see if it gets there. Reduced TF current to 150 kA. Disrupted at 0.22 s. Current rise is indeed too fast.
Feb 29 2008 04:33:16:533PM	1080229030	Joseph Snipes	Shot 30: Reduced Ip to 0.8 MA. Disrupted at 0.57 s. Byford says there was a commutation fault following that disruption.
Feb 29 2008 04:54:17:760PM	1080229031	Joseph Snipes	Shot 31: Reduced Ip to 0.7 MA and ramped it to 0.9 MA starting from 0.4 to 0.5 s then ramped back to 0.7 MA from 0.7 s to 0.8 s. Good shot.
Feb 29 2008 05:01:28:410PM	1080229032	Joseph Snipes	Shot 32: Same current ramps but with the TF current set to 157 kA. Good shot.
