ENDX Ion Pump

I noticed that LLO was running their main ion pump at 7kv in the end station. Ours was set to 5kv.

Today at 22:30 UTC I set the voltage to 7kv. The immediate response has been a small increase in pressure at PT510. We'll watch for a few days and see where it goes.

Here is the last 11 hours of pressure. Looks like the 7kv is doing its thing.
