We ran 32S5+ overnight. Keerthi has been working with the new surface source oven for the last couple of weeks. His results to come. Meanwhile, here are a stripchart of overnight beam plus a few panels after my tweaking. Slits are at 5mm position.
Observations:
- The heater responds smoothly in 0.1A steps.
- There is an optimal heater setting; more is not necesaarily more.
- As always, there are several RF resonances within a range.
- Higher resonance produces more beam but less stable.
- Lower resonance produces less beam but more stable.
- Optimal heater loading technique and current setting will require further study.

Last stripchart is FC6 starting a couple of minutes before shutting off the heater.
Power down everything around 17:30, and turn off IOS turbos. I have left IOS:IV0 open to ensure the intermediate section gets vented before the cart is removed. I am leaving the MCIS turbos on for now,. to continue pumpimg residual sulphur. |
