Run plan: 1101217 MP624: Measurements of mode converted waves in D-He3 plasmas with phase contrast imaging Bt: 8.0 T Ip: 1.0 MA nl04 ~ 0.8e20-1.0e20 m^-2 He3 puff Working Gas Species: D2 Boronization Requested: No Standard ECDC Overnight Diagnostics: Standard profile measurements, PCI, ECE (8 T) -- The goal is to get mode conversion measurements at low He3 fraction using D and E antennas. We will start from low power to minimize the effect of energetic minority tail. Hopefully, this will give us more reliable measurements than what we get from J antenna, which is 144 degrees away from PCI. Power scan will be done as time permits. -- 1. Start from shot 1100210007 (8 T, 1.0 MA, nl04 = 0.8, USN), 150 ms He3 puff, 0.5 MW ICRF. Adjust He3 puff in the subsequent shots if necessary. RF for 0.75-1.20 s one at a time. Focus on D and E antenna measurements, and take some with J. 2. Power scan Increase RF power to 1.0 and 1.5 MW.

Engineering setup for Friday 12/17/2010 MP624: Measurements of mode converted waves in D-He3 plasmas with PCI Session leader: N. Tsuji Physics operator: G. Wallace Overnight: no boronization. ECDC: Standard overnight ECDC. Run will start at 09:00 and end at 17:00. Power systems as on 1100811019 (Ip=1.2 MA, 7.9 T, nl_04=1.1e20 m-2, LSN) NOTE: alternator RPM will have to be increased to ~1715 for this 8 tesla run. NOTE: PLC limits on TF will have to be increased to be consistent with 225 kA. A-coil configuration: +Dtop -Dbot -Jtop +Jbot; Hybrid enabled (standard configuration) Gas Setup: fill B-Top with 6 psi D2 Hybrid enabled (PG4) fill B-side lower with 1 psi Ar Hybrid enabled (PG1) fill B-side upper with 15 psi He3 Hybrid ENABLED (PG2) fill B-main (C-side) with 40 psi D2 Hybrid enabled (PG3) leave NINJA as is Enable the following gate valves and shutters, assuming no vacuum problems: ECE, VUV, Z-bolo, HIREX-Sr, B-spectrometer GV Torvac setup: keep gate valves open during PULSE Specific diagnostics: TS, TCI, PCI, ECE (at 8T) ------------------------------------------------------------------------------ Boronization: no overnight; no between-shot Impurity injector: no ICRF Setup: YES, 0.5-1.5 MW each from D, E, J LH Setup: no DNB: no Cryopump: no ------------------------------------------------------------------------------ Run plan: This will be an 8 tesla run, so load seg 1 from seg 1 of 1100811019. Changes: use gas prefill settings from 1101216 (non-cryo) startup. Load seg 2 from seg 2 of 1100210007. Changes: add 150 ms He3 puff. Stop TF ramp at 6.0 T (167 kA) for first shot to make sure TF diagnostics are working properly. Increase TF ramp to 225 kA if all goes well after first shot. Set Ip to 1.0 MA. Use TF timing from 1100811019 (0.5 s flattop). Alternator RPM will have to be increased to ~1715. PLC limits on TF will have to be increase to allow 225 kA for 8 T operation.

Overall a successfull run. It took some time to optimize the He3 fraction for good MC layer location and large signal. With 80 ms puff, He3 fraction was around 0.09-0.11, and this was about the optimum for E antenna. The signal from E antenna was higher than J in general, which is what is expected qualitatively. Quantitatively, the observed signal level for E was still low compared to simulations. We tried to modify D antenna frequency to 78 MHz, and finally got it running at the 3rd last shot. The difference between J and D was not immediately obvious. This may partly be due to lower coupling of D antenna power to the core, as indicated by the trips of the antenna.

Run summary from 1101217 Physics Operator: G. Wallace Session Leader: N. Tsuji MP624: Measurements of mode converted waves in D-He3 plasmas with PCI This was an 8.0 T run to look at D-He3 mode conversion with PCI at 80 MHz. C-Mod was running well all day with only two fizzles. Increasing puffing on PG4 and PG3 stopped the fizzles. TF values of 7.9 T (224 kA) and 8.0 T (227 kA) were successfully achieved, although many cell accesses were required to inspect and replace blown fuses. Shot cycles were taking about 25 min to complete due to the extended cooling time at these TF current values. Only 18 shot cycles were obtained. A He3 puff of ~80 ms was required to achieve the desired mode conversion. Some problems were encountered with disruptions during the rampdown due to vertical instability. This was fixed by starting the ramp down of CLEARIN and RCUR a little earlier. Much effort was made by the RF group to retune their transmitters for slighly lower frequency. At 8.0 T the mode conversion layer was slightly on the high field side of the PCI viewing chords for 80.5 MHz. Decreasing the frequency by a few MHz helped to see the mode conversion better. Scorecard: Shot cycles: 18 Fizzles: 2 Duds: 0 Plasmas disrupted in rampdown: 6 Plasmas with complete rampdown: 10

Session Leader Comments
Dec 17 2010 10:52:43:973AM	1101217002	Naoto Tsujii	J, 0.5 MW. He3 fraction ~0.11. Signal is very low, but may be expected for J.
Dec 17 2010 10:53:04:687AM	1101217003	Naoto Tsujii	J, 1.0 MW. He3 fraction >0.13. A bit high.
Dec 17 2010 10:52:10:240AM	1101217004	Naoto Tsujii	Still He3 ~0.10. Try changing D antenna frequency.
Dec 17 2010 01:12:29:217PM	1101217006	Naoto Tsujii	50 ms He3. No signal. Probably only minority heating.
Dec 17 2010 01:13:58:643PM	1101217007	Naoto Tsujii	100 ms He3 puff, He3 frac ~0.10. E at 0.5 MW, signal ok.
Dec 17 2010 01:19:00:413PM	1101217008	Naoto Tsujii	100 ms He3 puff, He3 frac ~0.10.
Dec 17 2010 01:20:02:947PM	1101217009	Naoto Tsujii	80 ms He3 puff, He3 frac ~0.09(?). Mode conversion is much smaller compared to shot 7 (He3 frac ~0.10).
Dec 17 2010 01:28:07:680PM	1101217010	Naoto Tsujii	100 ms He3 puff, He3 frac >~0.10. Mode conversion appreciably larger compared shot 7.
Dec 21 2010 11:08:55:097AM	1101217011	Naoto Tsujii	100 ms He3 puff, He3 frac >~0.11. Signal seems larger, but He3 fraction might be somewhat higher.
Dec 17 2010 02:22:03:483PM	1101217012	Naoto Tsujii	90 ms He3 puff, He3 frac >0.11. Signal level seems close to what is expected, but considering sensitivity to the He3 fraction, and uncertainty of it, it's hard to be conclusive.
Dec 17 2010 03:21:40:303PM	1101217013	Naoto Tsujii	60 ms He3 frac ~0.09. Signal is comparable to shot 7.
Dec 17 2010 03:25:43:267PM	1101217014	Naoto Tsujii	80 ms He3, frac ~0.09. Both MC location and signal level around the optimum for E antenna. Signal from J is 10 times smaller, which is consistent with the previous measurements.
Dec 21 2010 11:30:23:307AM	1101217015	Naoto Tsujii	E, J at 1.0 MW. Signals slightly more than twice the privous 0.5 MW shots.
Dec 17 2010 04:18:39:233PM	1101217016	Naoto Tsujii	Finally got D at 0.3 MW. Signal per MW larger than J, comparable to E.
Dec 17 2010 06:34:16:427PM	1101217017	Naoto Tsujii	He3 frac ~0.11. D and J at the same power level. Although D did not run steadily, signal from D is about twice as high as J.
Dec 17 2010 06:37:39:230PM	1101217018	Naoto Tsujii	He3 frac ~0.11. Longer D and J pulse. It is hard to see the difference for this shot.

Physics Operator Comments
Dec 17 2010 09:17:51:680AM	1101217001	Greg Wallace	Result: Fizzle. Pressure is a little low at startup (5-6 mtorr). TF looks OK. Next shot: Go to 8.0 T for next shot. Increase PG4 puff from 25 ms to 28 ms to increase pressure at breakdown.
Dec 17 2010 09:36:46:287AM	1101217002	Greg Wallace	Changes: Go to 8.0 T. Increase PG4 puff from 25 ms to 28 ms to increase pressure at breakdown. Result: Plasma! 1.0 MA, 7.9 T. Disruption in rampdown due to vertical disruption. Startup a little bouncy but will leave it alone for now. Next shot: Reduce programmed nl_04 from 8e19 to 7e19. Reduce He3 PG2 puff from 150 ms to 100 ms.
Dec 17 2010 09:58:31:130AM	1101217003	Greg Wallace	Changes: Reduce programmed nl_04 from 8e19 to 7e19. Reduce He3 PG2 puff from 150 ms to 100 ms. Result: Plasma to rampdown. Still a little bounce in the startup; will ignore for now. Density much lower in this shot. Next shot: Increase nl_04 programming to 8e19 during flattop. Also move the start of the density flattop a little earlier. Increase TF current from 224 to 227 kA. Start TF rampdown at 1.21 s instead of 1.25 s to compensate for additional heating in TF SCR.
Dec 17 2010 10:38:12:410AM	1101217004	Greg Wallace	Changes: Increase nl_04 programming to 8e19 during flattop. Also move the start of the density flattop a little earlier. Increase TF current from 224 to 227 kA. Start TF rampdown at 1.21 s instead of 1.25 s to compensate for additional heating in TF SCR. Result: Plasma. Another disruption in rampdown. Got 7.99 T. Still a little bounce in startup. Several blown fuses in the power room---engineers are working to replace them. Next shot: Reduce PG2 puff (He3) from 100 ms to 50 ms.

Dec 17 2010 12:53:56:680PM	1101217008	Greg Wallace	Changes: Increase RCUR offset in seg 1 from 2500 to 3500 to reduce bounce. Result: Plasma. Still having disruption in rampdown. Increasing RCUR offset helped with bounce. Next shot: Decrease He3 PG2 puff from 100 ms to 80 ms.
