MP430 - Between shot boronization

Plasma setup like 1060329005

Assume 10 minute boronization length to start with. Pressure 5
mTorr. Pause at center of each scan. Steady ECDC, no pulsing.

To reduce fizzles after boronization the prefill is greatly reduced
see 1050810xxx and wait to get the pressure down to <2.5x10-6 Torr
We will start using static fill, rather than the prepuff.

-1) Establish plasma operation with RF.

1) Establish plasma and RF power for suitable fiducial

2) Boronize sequence (1 shot to measure effect, 2nd shot to determine
if it has worn off) using 10 cm wide scans to cover from 90 to 50
cm. Work from outer major radius inward in 10 cm steps.

3) Once done with the scan, return to the most effective
location to examine reproducibility.

4) Scan using 5 cm stepsize on either side of the best location.

Potential next steps

- Switch in 10% diborane 90% He mixture bottle.

- Compare the usual boronization including pulsed ECDC with leaving
the ECDC on steadily during the period.

- If not done earlier then reduce the length of boronizations now to
10 and 5 minutes length (4 shots min. if not including fizzles).

- Compare boronization lifetime by comparing D&E heated versus J heated.

1060405 - MP#430 'optimization of boronization location'

We did optimize the boronization process today. Several factors contributed to this. First, we learned that the pre-breakdown puff was better than the static fill for getting breakdown; With static fill we had 2 fizzles following a boronization. With the pre-puff we often had no fizzles. The second factor is that we learned a little about shortening the boronization process; Filling the machine with diborane can be done in parallel with the magnet resistance measurements saving ~ 5 minutes. We also found that we could start into init at higher pressures saving some time as well. The above, together with the engineering operators efficiency gains, led to a time between shots (at when init starts) of ~ 17 minutes on the big board time in the best case.

One small additional change we made - we changed the relative sweep period and dwell time for the boronization. We kept the 20 sec dwell, but lengthened the sweep (which includes the dwell time) from 60 to 200s. We could consider eliminating the dwell completely. But, don't forget, although we do not think this change will have a big effect we cannot rule it out.

We would like to compare this data, with 20% diborane, to the data from 1050705, when we last did a boronization location study with 78 MHz (1050810 was 50MHz on J-port, with a He3 resonance, so the erosion of the boronization erosion could be different). All shots today had rapidly decreasing confinement during the shot. It appears that it is faster than for 1050705; For example shots 1050705009 and 12 at 20 minutes boronization with 10% diborane have slower energy delay than shot 23 from today. So, although the stored energy from today matches that of 1050705, the degradation is faster, perhaps more like the 10 min. boronization shots from that day.

The main goal of today, repeating the same boronization, but centered at different radial locations, was not accomplished. The problem was that the boronizations were not reproducible. The first 2 boronizations were done with the pressure under pressure feedback. It was clear that the pressure could not be controlled well. In one case I observed the pressure dropped below 1 mT for several minutes (the gauge onle reads down to 1 mT) and then jumped up to 14 mT; 5 mT was what was programmed. After the first 2 boronizations the operators switched to manual control but this was only marginally better. Because of all the efforts to get the pressure right the lengths of boronizations also varied beyond the 10 minutes requested. We hoped to make some sense of how much pressure variation there was by looking at the historian data. Unfortunately only 5 out of 10 were recorded in the trend data. The problem, in the end, was with the valve. It died in the 'open' position during the last boronziation.

For further reference the following shots are of interest:

4: no boronization, for comparison
7: first shot after 85-95 cm boronization
10: first shot after 75-85 cm boronization
11: second shot after 75-85 cm boronization
14: first shot after 65-75 cm boronization
15: second shot after 65-75 cm boronization
17: first shot after 55-65 cm boronization
18: second shot after 55-65 cm boronization
19: first shot after 45-55 cm boronization
20: second shot after 45-55 cm boronization
21: first shot after 75-85 cm boronization
22: second shot after 75-85 cm boronization
23: first shot after 70-80 cm boronization
24: second shot after 70-80 cm boronization
25: first shot after 65-75 cm boronization
26: second shot after 65-75 cm boronization
28: first shot after 60-70 cm boronization
29: second shot after 60-70 cm boronization

The time between shots (after a boronization) is as follows:

shots 4-7: 58 minutes
shots 7-10: 58:39
shots 11-14: 68:24
shots 15-17: 54:06
shots 18-19: 35:21
shots 20-21: 28:12
shots 22-23: 24:23
shots 24-25: 24:31

The 'standard' shot rate appears to be around 13 minutes. So, the 10 minute boronization added about 11 minutes time to between shots. It is possible to trim mor etime off the boronization schedule but it will need better gas changeover control and trying shots when the pressure is higher in the machine.

If we repeat this run then, of course, we will need to redo the scans. But, we should aim to vary the pressure as well- if we could raise the pressure and boronize for a shorter period then we could shorten the boronization further.

PO Summary for Run 1060405 Boronization localization

SL: Blip
PO: Irby

We began by establishing a LSN plasma on shots 01 to 04. Shot 05 was
a dud following the first boronization. I had reduced the static fill
pressure to 6.5e-6 Torr, which was clearly too low, but consistent
with fill pressures obtained during pre-puffs on run 1050810. We then
spend a few more shots searching for a good static fill pressure
following boronization, but finally gave up on shot 16, when we went
back to a pulsed gas prefill. Going to a 6 ms gas puff for the first
shot following a boronization, and then going to 16 or 18 ms for the
2nd shot produced a very good string of discharges. We also had one
nice 2nd shot startup with a 6 ms pre-puff.

*****************
So the prescription for getting a discharge following between shot
boronization is the same as it was last year: reduce pre-puff to
6 ms for the 1st shot. Then increase pre-puff to 16 or 18 ms for
the 2nd and following shots.
*****************

Shot 23 was the best performance discharge of the day with 199 kJ of
stored energy. The ECDC scan for this shot was 70/75/80 cm.

We had trouble from the beginning of the run today controlling the
pressure during the boronization. By going to manual control of the
voltage on the piezo valve we were able to control it most of the day,
but we had to stop the run following shot 29 because the piezo failed
in an open condition. The machine would immediately fill with gas
when we tried to initiate the boronization.

Apr 5 2006 09:17:45:570AM1060405001Bruce Lipschultz1 MA, nl04=1e20, fiducial shot. J tripping a bit. Repeat before boronization.

Repeated short H-modes.
Apr 5 2006 09:33:17:900AM1060405002Bruce Lipschultz1 MA, nl04=1.1e20. We seem to have lost a fringe on the interferometer leading to slightly higher density and that caused higher pressures at the antennas and J had problems. D antenna did as well?

H-factor ~ 1.4 with 2 MW.

Repeat and try to get things (density and ICRF) settled.
Apr 5 2006 09:55:15:527AM1060405003Bruce Lipschultz1 MA, nl04=0.75e20. No interferometer fringes lost and too low a density. So set the density programming back to 1.0

H-factor ~ 1.0 with 3 MW.

Repeat and try to get things (density and ICRF) settled.
Apr 5 2006 10:23:58:197AM1060405004Bruce Lipschultz1 MA, nl04=0.9e20.

OK to go for between shot boronization (10 minutes, scan from 85-95 cm, dweel at 90 cm, no pulsing).

At the moment the boronization is set for 20 seconds of dwell (at one spot) out of a 60 second sweep period.
