We are going to try and calibrate the various valves and plena to be used in tomorrow's run for impurity seeding.

The idea is to cross-calibrate H-bottom, B-side-lower, B-div and H-div by filling them all to the same pressure Ne, injection for 100 ms using 75% duty factor, and looking at the pressure rise in the vessel. That will be compared to the pressure drop in the individual plena.

We're going to do several gas-into-empty-torus shots to calibrate four different gas valves (B-side-lower, H-bottom, B-divertor, H-divertor), corresponding to PG1, PG5, PG6, PG7). The plena have been loaded with 20 psi of neon, and a 100 ms pulse starting from t = -1.9 s has been loaded into all the corresponding valve waveforms in seg 1. The waveform amplitude is 75. Gas Setup: leave B-Top as is Hybrid DISABLED (PG4) fill B-side lower with 20 psi Ne Hybrid enabled (PG1) leave B-side upper as is Hybrid DISABLED (PG2) leave B-main (C-side) as is Hybrid DISABLED (PG3) fill H-bottom with 20 psi Ne Hybrid DISABLED (PG5) fill B-div with 20 psi Ne Hybrid DISABLED (PG6) fill H-div with 20 psi Ne Hybrid DISABLED (PG7) leave NINJA as is DISABLED Torvac setup: keep gate valves closed for 25 seconds after pulse

Feb 13 2012 12:22:47:510PM 1120213001 Bruce Lipschultz First shot - 01 - B-side lower. The pulse for this valve and all the following ones will come at -1.9 seconds. Valve not set for hybrid enable.

Feb 13 2012 12:30:19:980PM 1120213002 Bruce Lipschultz shot 2 - B-side lower: gas went - 0.8 torr-liters according to 4060*G-side MKS. Actual pressure of 0.22 mT peak.

BUT - the gate valves were not closed and the pressure was dropping. So repeat.

Feb 13 2012 01:06:21:837PM 1120213003 Bruce Lipschultz shot 3 - B-side lower: gas went - 1.17 torr-liters according to 4060*G-side MKS. Actual pressure of 0.3 mT peak.

The piezo plenum read 1.49 tl peak, 1.02 tl at 15s

This was 75% duty factor

The MKS gauge on the B-side lower plenum seems to have a major droop and a zero offset.

Feb 13 2012 01:35:11:143PM 1120213004 Bruce Lipschultz shot 4 - B-div: gas went - 1.75 torr-liters according to 4060*G-side MKS. Actual pressure of 0.43 mT peak.

The piezo plenum reads 2.14 tl peak, 1.4 tl at 17s.
BUT, did we get 100% duty factor? No, since it is chopped in hardware the mout 22 should read 7.5 which it does

Feb 13 2012 01:04:16:960PM 1120213005 Bruce Lipschultz shot 5 - H-div: gas went - 1.85 torr-liters according to 4060*G-side MKS. Actual machine pressure of 0.46 mT peak.

MKS on H-div piezo plenun read 2.3 tl peak, 1.6 equilibrium at 15 seconds

BUT, did we get 100% duty factor? No, since it is chopped in hardware the mout 22 should read 7.5 which it does

Feb 13 2012 01:19:27:313PM 1120213006 Bruce Lipschultz shot 6 - H-bottom: gas went - 0.975 torr-liters according to 4060*G-side MKS. Actual machine pressure of 0.24 mT peak.

Feb 13 2012 01:18:13:080PM 1120213006 Robert Granetz
Shot 06 -- H-bottom (PG5) fired neon for 100 ms with torus gate valves closed for 25 s.

Feb 13 2012 01:25:15:667PM 1120213007 Robert Granetz
Shot 07 -- Fire B-divertor with 15 psi neon in its plenum

Feb 13 2012 01:42:27:803PM 1120213008 Robert Granetz

Shot 17 -- Fire B-divertor with 400 ms pulse starting at t = -1.0 s, 15 psi neon in plenum, and programmed amplitude of 50. This is to look at the overshoot/droop in the plenum pressure measurement, trying to discern whether it's an overshoot at the beginning, or a droop over longer timescales.

Feb 13 2012 03:14:10:353PM 1120213018 Robert Granetz
Shot 18 -- Fire H-divertor with 100 ms pulse starting at t = -1.0 s, 15 psi neon in plenum, and programmed amplitude of 75. This is the last gas calibration shot today.

Session Leader Comments
Feb 13 2012 12:22:47:510PM	1120213001	Bruce Lipschultz	First shot - 01 - B-side lower. The pulse for this valve and all the following ones will come at -1.9 seconds. Valve not set for hybrid enable.
Feb 13 2012 12:30:19:980PM	1120213002	Bruce Lipschultz	shot 2 - B-side lower: gas went - 0.8 torr-liters according to 4060*G-side MKS. Actual pressure of 0.22 mT peak. BUT - the gate valves were not closed and the pressure was dropping. So repeat.
Feb 13 2012 01:06:21:837PM	1120213003	Bruce Lipschultz	shot 3 - B-side lower: gas went - 1.17 torr-liters according to 4060*G-side MKS. Actual pressure of 0.3 mT peak. The piezo plenum read 1.49 tl peak, 1.02 tl at 15s This was 75% duty factor The MKS gauge on the B-side lower plenum seems to have a major droop and a zero offset.

Physics Operator Comments
Feb 13 2012 12:39:00:660PM		Robert Granetz	We're going to do several gas-into-empty-torus shots to calibrate four different gas valves (B-side-lower, H-bottom, B-divertor, H-divertor), corresponding to PG1, PG5, PG6, PG7). The plena have been loaded with 20 psi of neon, and a 100 ms pulse starting from t = -1.9 s has been loaded into all the corresponding valve waveforms in seg 1. The waveform amplitude is 75.
Feb 13 2012 12:11:17:837PM	1120213001	Robert Granetz	Shot 01 -- B-side-lower, 100 ms, neon. Torus GV will stay closed for 25 s.
Feb 13 2012 12:16:46:080PM	1120213001	Robert Granetz	Shot 01 -- no gas...operator error Next shot: try again with B-side-lower set to hybrid enabled
Feb 13 2012 12:27:31:497PM	1120213002	Robert Granetz	Shot 02 -- B-side-lower (PG1) fired for 100 ms. But the torus gate valve remained open. Next shot: try again, this time with the torus GV closed for 25 s.
Feb 13 2012 12:35:44:750PM	1120213003	Robert Granetz	Shot 03 -- B-side-lower (PG1) fired neon for 100 ms with torus gate valves closed for 25 s. Next shot: enable B-divertor (PG6), disable B-side-lower
Feb 13 2012 01:02:31:540PM	1120213004	Robert Granetz	Shot 04 -- B-divertor (PG6) fired neon for 100 ms with torus gate valves closed for 25 s. Next shot: enable H-divertor; disable all others
Feb 13 2012 01:02:43:670PM	1120213005	Robert Granetz	Shot 05 -- H-divertor (PG7) fired neon for 100 ms with torus gate valves closed for 25 s. Next shot: enable H-bot; disable all others
Feb 13 2012 01:18:13:080PM	1120213006	Robert Granetz	Shot 06 -- H-bottom (PG5) fired neon for 100 ms with torus gate valves closed for 25 s.
Feb 13 2012 01:25:15:667PM	1120213007	Robert Granetz	Shot 07 -- Fire B-divertor with 15 psi neon in its plenum
Feb 13 2012 01:42:27:803PM	1120213008	Robert Granetz	Shot 08 -- Fire B-divertor with 15 psi neon in its plenum, but move the 100 ms pulse to start at t = -1.0 s (instead for -1.9 s)
Feb 13 2012 01:38:04:983PM	1120213009	Robert Granetz	Shot 09 -- Fire B-divertor with 100 ms pulse starting at t = -1.0 s, 15 psi neon in plenum, and programmed amplitude of 100 (instead of 75)
Feb 13 2012 01:49:30:180PM	1120213010	Robert Granetz	Shot 10 -- Fire B-side-lower with 100 ms pulse starting at t = -1.0 s, 20 psi neon in plenum, and programmed amplitude of 100
Feb 13 2012 01:59:55:070PM	1120213011	Robert Granetz	Shot 11 -- Fire B-side-lower with 100 ms pulse starting at t = -1.0 s, 20 psi neon in plenum, and programmed amplitude of 95
Feb 13 2012 02:06:14:980PM	1120213012	Robert Granetz	Shot 12 -- Fire B-divertor with 100 ms pulse starting at t = -1.0 s, 15 psi neon in plenum, and programmed amplitude of 95
Feb 13 2012 02:14:47:430PM	1120213013	Robert Granetz	Shot 13 -- Fire B-divertor with 100 ms pulse starting at t = -1.0 s, 15 psi neon in plenum, and programmed amplitude of 50
Feb 13 2012 02:20:23:550PM	1120213014	Robert Granetz	Shot 14 -- Fire B-side-lower with 100 ms pulse starting at t = -1.0 s, 20 psi neon in plenum, and programmed amplitude of 50
Feb 13 2012 02:30:35:040PM	1120213015	Robert Granetz	Shot 15 -- Fire B-side-lower with 100 ms pulse starting at t = -1.0 s, 20 psi neon in plenum, and programmed amplitude of 20
Feb 13 2012 02:38:53:543PM	1120213016	Robert Granetz	Shot 16 -- Fire B-divertor with 100 ms pulse starting at t = -1.0 s, 15 psi neon in plenum, and programmed amplitude of 20
Feb 13 2012 03:07:16:000PM	1120213017	Robert Granetz	Shot 17 -- Fire B-divertor with 400 ms pulse starting at t = -1.0 s, 15 psi neon in plenum, and programmed amplitude of 50. This is to look at the overshoot/droop in the plenum pressure measurement, trying to discern whether it's an overshoot at the beginning, or a droop over longer timescales.
Feb 13 2012 03:14:10:353PM	1120213018	Robert Granetz	Shot 18 -- Fire H-divertor with 100 ms pulse starting at t = -1.0 s, 15 psi neon in plenum, and programmed amplitude of 75. This is the last gas calibration shot today.
