Trigger channel problem: while Trigger ch-11 (HGTD) has a healthy TTL signal as usual, our regular Caladium Trigger ch-10 (NIM) appeared to be totally dead. Sending TRG11 to a TTL->NIM converter didn't get any NIM output and eventually realized that the NIM<->TTL converter is a bad module. Grabbed another NIM<->TTL from ESA upstairs and this finally worked. We are not driving the TLU trigger from TRG11 after TTL->NIM.
4:45am Asked for beam bu but MCC couldn't get it going - cooling water for kicker magnet too cold ! MCC tried several times with no success.
10:30am Still cannot turn on magnet. Give up. Moved Caladium out of beam line for T577 to take over day shift.
