Valved in aux carts and continued to pump IP2,3 today. This evening I turned HV ON and both are maintaining so far. Because IP3 is a newly rebuilt pump, I valved out the aux cart for the evening. If it checks out tomorrow morning, we can decouple that cart and use it on the NEGs. IP2 is currently at 7kV and 715 uA. I left pump cart valved into IP2 for the night.
