Hydrogen recovery using disruptions The purpose of these experiments is to force hydrogen recovery from the material surfaces in C-Mod by thermal desorption by intentionally disrupting plasmas. Special experimetnal requirements - Gate valves close during shot and 3 minutes afterward - We will possibly want to be able to vary the gate valve close time during the run - Pre and post shot RGA-1 on the bypass valve is essential Plan The plan is to use the same shots (5.4 T, 1 MA) as being used for the FFT tests, which after FFT works will include a Ip scan. Fizzle strategy is uncertain. We'll evaluate whether or not the fizzles are unecessarily delaying plasma ops during the run. Unlike previous H/D recovery days we'll use ICRF to achieve H-mod and higher W_th, and hopefully more robust H recovery. Therefore we will use (obviously) the latter part of the shot. Nominally we'll wait ~100 ms after the FFT ICRF (E?) to start the setup of our target plasma for the VDE. The VDE timing needs to be set by the physop to be consistent with the FFT timing. (2 shots/disruptions per step) 1. Check back on standard downward Ohmiv 1 MA VDE and diagnose H/D recovery Reference shot: 1070405018 2. Repeat with 0.5 MW ICRF (whatever sources ICRF recommend) 3. " " 1 MW 4. " " 1.5 MW 5. " " 2 MW We would like to get these done at 1 MA, but will welcome higher Ip to increase W_th.

Only 4 good plasmas, shot 5, 6, 8, and 10. (delay in FFT preparation, I2t board problem in the morning, and flux loop F10 problem after shot 10) The FFT system has been tested to L-mode at 200 kW Pforw level. After some adjustments and bug fixing, it worked well in shot 10. The system got a near perfect match (<3% power reflection) 2.5 ms after the RF power was above the pre-set threshold (50 kW). And stayed matched the whole time with RF power on. We did't have enough plasma to test the L-H transition, density scan, and current scan etc. However, based on the information we have, the FFT matching should be better in H-mode. We didn't have chance to test the power handling capability either. At 200 kW forward power, the FFT was good at handling about 400 kW circulating power.

Four total VDE at 1 MA. Two went down, which released very little gas (~1-2 Torr-L net release when taking into account fuelled D2) indicating this region had been "conditioned" already Two VDE's went up, which releases much more gas ~80 Torr-L with a substantial (~40%) fraction of Hydrogen. The last VDE (#010) seems to have caused a short in F10. The VDE charactertics (halo current, Wth at disruption) were not outside the norm for "regular" C-Mod VDE, so not sure what happened.

It was a very difficult run. The run was delayed initially for the ICRF guys to fix the fast ferrite tuner. Then, we had a series of I^2t faults due to a faulty EF1 shunt. By shot 5, we got plasma and the programmed disruption for Dennis Whyte. Then, we got a second disruption that was then followed by alternating fizzles and disruptions for a total of four plasmas each with programmed vertical disruptions. After shot 10, flux loop F10 had a 0.7 V offset and Granetz went into the cell to put a charged capacitor across the leads of the flux loop to attempt to clear the intermittent fault in the flux loop. We then did a series of EF3 only test shots under PLC control to check out the flux loop. All tests indicated that the flux loop measured far less flux than its comparable loop. So, the flux loop appears to be shorted in two places around the vessel so that it is not measuring the correct amount of flux. This flux loop is important for machine operation. So, the run has been cancelled. Perhaps, something can be done to either repair the loop or reprogram the software to no longer use F10.

Session Leader Comments
May 1 2007 07:22:38:743AM		Yijun Lin	A big leak found on FFT#2 elbow (a bad welding). The filled gas had a small amount of SF6. This leak has causes some trouble on TCI laser. We will have to vent the section and refill with N2 only, and not to run E port exceeding 1 MW.
May 1 2007 09:45:30:283AM		Yijun Lin	Check out the fault signal from the fft (connected to the transmitter fault chain) test shot 3505: fault signal -5.25 V. (FFT 1 fault). test shot 3506: fault signal at 2.6 V. (fft 2 fault) Now: source ready bypassed. Connect Kalmus to the coaxial line. test shot 3507: FFT power threshold set at 10 kW. Kalmus power to the vacuum. The FFT computer should not do anything. I should get data from on the Pforw, Prefl, etc. Got power. test shot 3508: Lower FFT threshold to 0.15 kW, so that it will fire. No current. Debugg...two enabling wires were not connected. Should have fixed. test shot 3509: repeat. there was current. and one module was faulted out. Put back source ready and connect E port to normal operation. Set FFT power threshold to 10 kW.
May 1 2007 10:33:14:930AM	1070501001	Yijun Lin	5.4 T, 1 MA, standard plasma shot 1: FFT power threshold at 10 kW. E port: 3 x 20 ms pulse. 150 kW, 200 kW, and 200 kW. Expected to be in L-mode phase. To check out the behavior of the system. result: No plasma. No power shot. The FFT computer was timed out (no data, not triggered). I believe this is normal behavior because the real-time routine started in 'check' and was waiting for a pulse. The pulse did not come after the normal time delay (~40 seconds), so it was timed out. A long delay due to network problems.
May 1 2007 10:50:41:840AM	1070501002	Yijun Lin	no power test shot. A tube arc on FMIT #3 before this shot (see RF logs) FFT computer was not triggered again. Supposedly, the same cause as in shot 1.
May 1 2007 11:00:15:800AM	1070501002	Yijun Lin	2nd shot 2. Still no power shot.
May 1 2007 12:06:16:853PM	1070501003	Yijun Lin	again. breakers were pulled during check. No plasma shot. Found a broken shunt on I^2t board. Being repaired.
May 1 2007 12:35:50:570PM	1070501004	Yijun Lin	EF1L test. FFT computer was triggered. Ran as expected (that is, did nothing without RF power) Next: Plasma attempt
May 1 2007 01:13:06:717PM	1070501005	Yijun Lin	5.4 T, 1 MA, standard plasma FFT power threshold at 10 kW. E port: 3 x 20 ms pulse. 150 kW, 200 kW, and 200 kW. Expected to be in L-mode phase. To check out the behavior of the system. result: FFT did not work as expected. (oscillation). Suspected something wrong in I/V measurement. Cell entry. Found the FFT current and voltage signals are swapped. The real current was small though. The connections were corrected. Good news is that the Antenna ran. The match was close without FFT working properly. next: repeat.
May 1 2007 03:30:05:960PM	1070501005	Dennis Whyte	Downard ohmic VDE at 1 MA 17 Torr-L D2 injected ~18 Torr-L gas recovered after shot (gate valves close 3 minutes) RGA-1 is not working today, so we're reading the old RGA by hand in the period after the gate valve opens to get relative gas composition H2 1.4e-6 HD 6.7e-6 D2 1.9e-5 Note the very small gas recovey (barely above the injected gas) and very small H2. These are the smallest gas recoveries we've seen in this conditioning period, suggesting we've cleaned out the lower divertor + shelf.
May 1 2007 01:40:46:340PM	1070501006	Yijun Lin	5.4 T, 1 MA, standard plasma FFT power threshold at 10 kW. E port: 3 x 20 ms pulse. 150 kW, 200 kW, and 200 kW. Expected to be in L-mode phase. To check out the behavior of the system. result: It indeed worked. I changed l_stub1_init to 1.55 m (from 1.60m) and l_stub2_init to 1.10 m (from 1.04 m) for next shot. There is noise on FFTDC2 higher than 10 kW (the threshold) when D port was on. Tighten DC1 power reflection threshold from 1% to 0.25%. Raise the power threshod to 50 kW to avoid running from D noise. next: longer pulse.
May 1 2007 03:32:41:413PM	1070501006	Dennis Whyte	Downard H-mode VDE at 1 MA, 1.5 MW Rf, W_th~72 kJ 18 Torr-L D2 injected ~21 Torr-L gas recovered after shot H2 8.4e-7 HD 1.2e-6 D2 2.3e-6 More H recovery with this higher stored energy than last shot, but still quite small.
May 1 2007 01:42:48:637PM	1070501007	Yijun Lin	fizzle
May 1 2007 02:21:46:060PM	1070501008	Yijun Lin	5.4 T, 1 MA, standard plasma FFT power threshold at 50 kW (either DC1 or DC2). E port: 200 kW, from 0.65 to 0.9 sec. Result: Still tried to run with D port. The offset at the matched point is worse. Next: 1. change program to look DC1 power threshold (still 50 kW). 2. change l_stub1_init to 1.63 from 1.55m, l_stub2_init to 0.99 m from 1.1 m (this adjustment is from calculation from DC2/DC1 data if there is FFT current). 3. longer pulse to 1.1 sec.
May 1 2007 03:42:02:150PM	1070501008	Dennis Whyte	Upward H-mode VDE at 1 MA, 1 MW Rf, W_th~52 kJ 18 Torr-L D2 injected ~100 Torr-L gas recovered after shot H2 5e-6 HD 9.6e-6 D2 6e-6 Significant H recovery with an UPWARD VDE, showing the history of desorption matters...since little total Joules have been put into the upper divertor.
May 1 2007 02:12:53:993PM	1070501009	Yijun Lin	fizzle
May 1 2007 03:41:02:980PM	1070501010	Yijun Lin	5.4 T, 1 MA, standard plasma FFT power threshold at 50 kW (DC1 only). E port: 200 kW, from 0.65 to 1.1 sec. Result: FFT #2 current overloaded at 0.9 sec. The overload signal shut off the transmitter (interlock worked). Found the interrupts were not disabled (which caused some missing computer cycle) Next: 0. disable the interrupts. 1. change the range of the demand so that we won't get overload. the current range to -130 to 130 A for both. (previously, -150 to 150 A) (the other thing is to raise the threshold in the cell. But it will take too much time). 3. change l_stub1_init to 1.62 m, l_stub2_init to .99 m
May 1 2007 03:44:25:120PM	1070501010	Dennis Whyte	Upward H-mode VDE at 1 MA, ~ 2 MW Rf, W_th~80 kJ 14 Torr-L D2 injected ~34 Torr-L gas recovered after shot H2 4e-7 HD 9.8e-7 D2 1.5e-6 H recovery smaller than with previous upward VDE.
May 1 2007 03:08:01:983PM	1070501011	Yijun Lin	dud. Flux loop problem. Cell access to fix it.
May 1 2007 04:02:07:207PM	1070501012	Yijun Lin	EF3 test. not good.
May 1 2007 04:17:51:917PM	1070501013	Yijun Lin	EF3 test. no good

May 1 2007 09:00:43:207AM	1070501001	Joseph Snipes	Waiting for the ICRF guys to fix the fast ferrite tuners to begin the run.
May 1 2007 10:03:15:010AM	1070501001	Joseph Snipes	Shot 1: Loaded shot 1070405018. Note that we are using segment 3 to force the disruption with a downward vertical position shift of about 2 cm starting at 0.89 s then the derivative and proportional gains of the fast ZCUR in wire 3 of segment 3 are turned off at 0.98 s, which leads to a disruption at about 1.03 s. The density is programmed for nl04 = 5 x 10^19 m^-2, Ip = 1 MA, and ITF = 150 kA. I^2t fault pulled the breakers in check. No power shot.

May 1 2007 12:48:28:340PM	1070501005	Joseph Snipes	Shot 5: Gate valves closed during the shot and for 3 minutes following the shot. Good shot. Disrupted as planned at 1.03 s.
May 1 2007 01:04:53:697PM	1070501005	Joseph Snipes	Cell access for ICRF et al.
May 1 2007 01:17:06:930PM	1070501006	Joseph Snipes	Shot 6: Moved disruption timing to a nominal 1.4 s to give the ICRF more time for FFTs. Good shot. Disrupted at 1.42 s.
May 1 2007 01:42:30:277PM	1070501007	Joseph Snipes	Shot 7: Fizzle!
May 1 2007 01:56:13:720PM	1070501008	Joseph Snipes	Shot 8: Reloaded segment 1 from shot 6 just to be sure that the early gas tweak did not change the startup. It does not look like it did since the gas valve does not open until about 0.025 s and the breakdown has already failed before that time on shot 7. Good shot. Disrupted at 1.42 s.
May 1 2007 02:16:17:730PM	1070501009	Joseph Snipes	Shot 9: Repeat. Fizzle.
May 1 2007 02:35:08:673PM	1070501010	Joseph Snipes	Shot 10: Corrected ZCUR wire 3 gains to go to zero at 1.46 s instead of 1.4 s so that the plasma has time to move under feedback control before the feedback is turned off. Good shot. Disrupted at 1.47 s. However, the plasma still disrupted upward.
May 1 2007 02:35:48:267PM	1070501010	Joseph Snipes	Flux loop F10 has a 0.7 V baseline offset. Granetz going into the cell to zap the feedthrough.
May 1 2007 03:01:35:433PM	1070501011	Joseph Snipes	Shot 11: Increased nl04 to 8 x 10^19 m^-2. Dud! It appears to be a problem with the F10 flux loop again. We will have another cell access to attempt again to repair F10.
May 1 2007 03:53:23:297PM	1070501012	Joseph Snipes	Shot 12: EF3 test under PLC control at 8 kA. F10 clearly measures lower flux than F18. So, it is not working properly.
May 1 2007 04:27:17:620PM	1070501013	Joseph Snipes	Shot 13: EF3 test under PLC control at 8 kA. F10 clearly measures lower flux than F18. So, it is not working properly.
May 1 2007 04:28:07:263PM	1070501014	Joseph Snipes	Shot 14: Swapped F09 and F10 to ensure that the problem is with F10. EF3 only test. The problem moved. So, F10 is broken. End of the run.
