    keyword=RQ1 current control

    Sorry, my mistake, the software regulator uses the current unless the field is very low. This was the reason the present control board in RQ1 was originally removed. The error in current setting becomes larger with more radiation damage, as was sustained in PREX. Since the background is presently much less it would be expected that the present offset will probably not change. If the RQ1 is stable enough, I expect it to remain so till Monday. If there is a need to replace the control board, I think we can read the parameters off the present board and set them on one of the newer control boards. That would make the process a bit more straightforward.
