    keyword=Cryo Problems Resolved (We Hope!)

    The word from the cryo-engineer is that when the Hall A IOC was rebooted this morning after it crashed whoever did it did not do a "crash recovery" but rather a "normal restore". The result is that the parameters for the PID loops controlling Hall A cryo levels were incorrect. They were some old values that are no longer valid. He says he did a proper restore and updated the PID parameters available to the "normal restore". We'll know for sure if this worked in about 15 minutes.
