SL Plan for run on MP 562 1. Start with shot 1100218028 but with Ip at 1 MA instead of 600 kA. ICRF timing from 1100218028. Power should be 2 MW from J and 1 MW from D (assuming there is no possibility of using E). This will be the fiducial shot for this run. CNPA setup: set F-top aperture to 204.5 and J-top aperture to 8.5. (2-3 shots) 2. RF power scan. This assumes we cannot use E Antenna. First 2.8 MW from J alone. Then 1.5 MW from J alone (may require aperture change). Then 1.5 MW from D alone. (5 shots) 3. Current scan. We had a lot of trouble with Ip at 800 kA so we'll try getting data at 600 kA and 1.2 MA. If these shots go well, we'll get another point at 750 kA. If we're struggling we'll move on to the field/phase scan. ICRF power should be the same as in the fiducial established in shot 1. 2 MW from J, 1 MW from D&E (5 shots) 4. Field and phasing scan: Change field to 5.6 T, current at 1 MA, ICRF power entirely from J but we want to switch the phase halfway through the shot. Half the ICRF pulses should be at 0,pi/2,pi,3pi/2 phasing and half the pulses should be at 0,3pi/2,pi,pi/2 phasing. Maybe repeat at 5.75 T (2-3 shots) 5. Density scan, increase density to nl04 = 0.9E20. If the CNPA signals are still reasonable, try increasing it to 1.2E20. (3-5 shots) 6. Modulation on top of steady state signal (if time): Keep D&E constant at 1 MW, modulate J 2 MW on top of the steady D&E signal. First shot should be at same plasma conditions as the fiducial. If this scheme produces interesting results, try at different currents. (1-? shots)

Summary for MP 562 We had a very successful run day hitting all the main points in the SL_Plan. RF scan: Got data at 0.75 MW, 2 MW, 3 MW and 4 MW of modulated power. Also got a comparison between D&E antennas and J antenna. Current scan: Got data at 1.2 MA, 1 MA, 0.8 MA and 0.6 MA. Had some trouble with CNPA noise at 0.6 and 0.8 MA Density scan: got data at nl_04= 1E20, the rest of the day was at 0.7E20. We also were able to get data on +90 vs. -90 J-Ant phasing at 5.6 Tesla and 5.4 Tesla. At the end of the run we were able to run another current scan, with 2 MW of ICRF power steady and 2 MW modulated. Had lots of runaways early in discharges, and some trouble with disruptions at the end of the day.

Machine generally ran well today. FMIT#2 was back on-line, and the rf also performed well providing 4 MW of modulated power for the MP. There were no startup field tweaks required today. The pre fill was changed only in an attempt to reduce runaways, not to improve startup, but changes in pre-fill and pg3 seg 1 puff produced no provable effect on the runaways. We had one fizzle today that may have been because of my reluctance to change the pre fill following disruption. No changes were required following the other disruptions (we had many). On shot 06 I changed ZCUR from -0.005 to 0.0 m to see if we could reduce W injections. This change seems to have worked. As we lowered the plasma current, I programmed an overshoot, keeping the current rise approx constant during startup. This procedure seems to have improved our control of the target density. Disruptions sometimes as early as 150 ms were caused mostly maybe completely by injections. Early in the run, we had a few W injections. At least one disruption seemed to be caused by massive boron injections in which Matt saw very bright second order lines. Others were moly. Runaways seem to be becoming more difficult to suppress. Shot 21 had very few runaways and also a high startup density and ratiomatic pressure around 30 ms when the x-ray signal begins to rise. Note that the standard neuts_hards detector with a BGO scintillator and PMT detector saturated often during the run at approx 600 (units of 10^12/s). The solid state detectors which did not saturate ranged up to 10,000 on some shots. We should spend some time understanding this problem (more time). jim Problems: EF1 failed to commutate on shot 01 EF1 reached current limits on several shots today which may have contributed to disruptions at higher currents. Main gas valve did not work on shots 01 and 02 --- re-seat of board again worked. No TF on shot 13 --- ok on shot 14 Data system hangs on a couple of shots Score: disruptions 03,05,11,20,26,27,28,29,30,33 dud 01,13 fizzle 26 plasma 02,03,04,05,06,07,08,09,10,11 12,14,15,16,17,18,19,20,21,22 23,24,25,26,27,28,29,30,31,32 33

Session Leader Comments
Mar 9 2010 09:08:47:627AM	1100309001	Aaron Bader	dud. EF1 issue. Next shot: fix ef1 and try again.
Mar 9 2010 09:25:01:803AM	1100309002	Aaron Bader	D ran well. But E and J both did not work. Next shot: try again to get 3 MW, increase later gas to get more constant density.
Mar 9 2010 09:44:13:260AM	1100309003	Aaron Bader	Early disruption, from Boron injection. F-top CNPA not happy at this power level, close aperture a little. Next shot: repeat
Mar 9 2010 10:03:52:207AM	1100309004	Aaron Bader	Good shot. ICRF good, and gas issue seems to be resolved. Tails may not reach steady state, they're close, so next shot we will increase on pulse length and reduce F-top aperture.
Mar 9 2010 10:18:18:380AM	1100309005	Aaron Bader	Early tungsten injection kills the plasma. Next shot: raise nl_04 to 0.7E20, raise zcur by 0.5 cm. Try to get rid of these W injections.
Mar 9 2010 12:15:52:437PM	1100309006	Aaron Bader	Good shot. No W injection. We can use this as a fiducial. Ip 1 MA, ICRF 3 MW, nl04 0.7E20 Next shot: ICRF power from J alone.
Mar 9 2010 12:16:28:377PM	1100309007	Aaron Bader	Plasma ran well, J-top a bit ratty. Ip 1 MA, ICRF 2.8 MW (from J only), nl04 0.7E20 Next shot: Lower to 2.5 MW from J and try again.
Mar 9 2010 12:17:21:203PM	1100309008	Aaron Bader	Plasma ran well, J-Ant ran well, CNPA ran well. A trifecta of useful data. No noticeable difference between tail energies on shots 8 and 6. Ip 1 MA, ICRF 2.5 MW (from J only), nl04 0.7E20 Next shot: 2.5 MW from D & E
Mar 9 2010 12:18:13:703PM	1100309009	Aaron Bader	E good, D has a lot of trouble. Startup also a bit rocky. Ip 1 MA, ICRF: 1.25 from E, 0-1.25 from D, nl04 0.7E20 Next shot: Repeat but put a little more of the power load on E. Invoke Irby magicks on startup.
Mar 9 2010 12:19:25:363PM	1100309010	Aaron Bader	Good plasma, antenna scan complete. Will forego the power scan for now, we'll return to it later. Start with current scan. Ip 1 MA, ICRF 1.35 from E 1.15 from D, nl04 0.7E20 Next shot: Raise current to 1.2 MA
Mar 9 2010 12:19:56:190PM	1100309011	Aaron Bader	Good plasma, density a little high and not constant. We had this same issue last time we tried this plasma, it's unclear that we will be able to get better density control. Ip 1.2 MA, ICRF 3 MW, nl04 0.9-0.7E20 Next shot: Move to 800 kA
Mar 9 2010 12:20:20:410PM	1100309012	Aaron Bader	Good plasma and RF. CNPA has some noise, but it's unclear that we can do better, so we go onwards with the run plan. Ip 800 kA, ICRF 3 MW, nl04 0.7E20 Next shot: move to 600 kA
Mar 9 2010 12:13:56:683PM	1100309013	Aaron Bader	no TF. next shot: redo 600 kA shot.
Mar 9 2010 12:30:41:813PM	1100309014	Aaron Bader	Good plasma. Lot's of noise on J-Top CNPA, as expected with this current level. We can get statistics for the higher energy ions but we're pretty hosed on the lower energy stuff. Ip 600 kA, ICRF 3 MW, nl04 0.7E20 Next shot: back to 1 MA and raise density to 1E20
Mar 9 2010 02:06:24:377PM	1100309015	Aaron Bader	Good plasma. Again, noise occurs on CNPA, but there is good signal on J-top Ch 6, which is probably the best we can hope for at this density. Ip 1 MA, ICRF 3 MW, nl04 1E20 Next shot: back to 0.7E20 and finish up the RF power scan we didn't complete earlier. So, 2 MW ICRF.
Mar 9 2010 02:07:38:503PM	1100309016	Aaron Bader	Good plasma and ICRF. Noise down on CNPA as expected. Ip 1 MA, ICRF 2 MW, nl04 1E20 Next shot: Start the phase scan. We'll increase field to 5.6 T to move the resonance in the middle of the J-Top CNPA. Change phase to +90 (0, pi/2, pi, 3pi/2)
Mar 9 2010 01:15:17:677PM	1100309017	Aaron Bader	Good plasma and ICRF. Noise is higher on J-Top than expected. We'll get around this by trying again with 2.5 MW from J only. Ip 1MA, ICRF 3 MW (J at +90 phase), nl04 0.7E20 (field 5.6 T) Next shot: same field, current and density. ICRF 2.5 MW from J only at 90 phasing.
Mar 9 2010 01:25:36:953PM	1100309018	Aaron Bader	Noise down on CNPA. Good plasma and ICRF. Ip 1MA, ICRF 2.5 MW (J only at +90 phase), nl04 0.7E20 (field 5.6 T) Next shot: J-Ant at opposite phasing.
Mar 9 2010 01:56:31:490PM	1100309019	Aaron Bader	There is a difference in the two phase values. Ip 1 MA, ICRF 2.5 MW (from J, phase -90) nl04 0.7E20 Next shot: redo fiducial shot 6.
Mar 9 2010 01:56:43:943PM	1100309020	Aaron Bader	early disruption next shot: retry
Mar 9 2010 02:16:37:107PM	1100309021	Aaron Bader	everything looks good. Ip 1 MA, ICRF 3 MW, nl04 0.7E20 next shot: change ICRF power to 4 MW
Mar 9 2010 02:32:18:437PM	1100309022	Aaron Bader	CNPA looks good. Seems to have survived the 4 MW Surprisingly little change in the CNPA signal between 3 and 4 MW Ip 1 MA, ICRF 4 MW, nl04 0.7E20 next shot: change ICRF power to 3 MW modulated and 1 MW solid.
Mar 9 2010 02:44:16:950PM	1100309023	Aaron Bader	CNPA looks good. A couple very brief cut outs on J-top, but we can work around them. Noise levels good. F-top has a couple more problems. Ip 1 MA, ICRF 4 MW (3 Modulated, 1 stead), nl04 0.7E20 next shot: change ICRF power to 2 MW modulated and 2 MW solid. close F-top aperture some more.
Mar 9 2010 02:59:28:530PM	1100309024	Aaron Bader	Everything good. F-top survived without any cutouts. J-top good as well. 1 trip on ICRF on the 8th pulse. Ip 1 MA, ICRF 4 MW (2 steady 2 modulated), nl04=0.7E20 Next shot: raise current to 1.2 MA
Mar 9 2010 03:13:21:127PM	1100309025	Aaron Bader	Plasma disrupts late. CNPA cuts out when ICRF trips on the 6th pulse. 9th pulse is also iffy. Ip 1.2 MA, ICRF 4 MW (2 steady 2 modulated), nl04=0.7E20 Next shot: lower current to 800 kA. Not sure if we'll survive this.
Mar 9 2010 03:25:57:890PM	1100309026	Aaron Bader	Fizzle Next shot: try again, lower current to 800 kA.
Mar 9 2010 03:43:49:833PM	1100309027	Aaron Bader	Good plasma and RF, but we forgot to change to 800 kA. CNPA saturated on most J-Top channels. Next shot: lower current to 800 kA.
Mar 9 2010 04:07:35:080PM	1100309029	Aaron Bader	Disruption Next shot: retry.
Mar 9 2010 04:22:59:753PM	1100309030	Aaron Bader	Disruption, but we may have enough data from this shot. Ip 800 kA, ICRF 4 MW (2 steady, 2 modulated) nl04 0.7E20 Next shot: try 700 kA
Mar 9 2010 04:42:38:790PM	1100309031	Aaron Bader	Early disruption Next shot: 900 kA shot. Keep D&E constant at 2 MW. Modulate J at 2MW with half the pulses at +90 phase and half at -90 phase.
Mar 9 2010 04:56:06:073PM	1100309032	Aaron Bader	Good shot. CNPA good. Ip 900 kA, ICRF D&E constant at 2 MW. Modulate J at 2MW with half the pulses at +90 phase and half at -90 phase, nl04 0.7E20 Next shot, same with field at 5.6T
Mar 9 2010 05:02:11:750PM	1100309033	Aaron Bader	Early disruption. Next shot: end of run.

After not being able to get signals from the 60 and 75GHz channels, Seung Gyou and I checked the power from the diodes and it was determined that both the 60GHz XMTR and 75 XMTR diodes have internal shorts. They are being sent for repair. The 50 and 88GHz channels, as well as the variable and 140GHz channels are functioning but will be reinstalled today after the run.
