MCC calls. Same issue as before: the "capture" RF cavity (right after 5
MeV in the injector, I believe) has tripped because the water supply is
out of nominal temperature range. Interestingly, the water is too cold
(not what I would have guessed...). They are calling in an expert from
EES to look at the temperature control circuit, meanwhile they will try
to recover the system (assuming the temperature comes back in range,
which is apparently what it did the previous time, earlier this shift).
