    keyword=Moller quad power supply problem

    Earlier in the shift (~7:30 PM) we began Moller tuning with Yves in MCC and Sasha here. Long sad story short, the new Moller quad power supply can't change polarity - which is required for the new first quad. So, we had to give up on Moller commissioning for the evening and hope that the DC power group can help/fix this issue Monday. The 1st and 2nd quads need to be able to change polarity, but not the 3rd and 4th, so perhaps some power supply (and software) swapping can be accomplished if need be.
