16:00 Shift Start
SL: Z.-E. Meziani, TO: N. Sparveris, 3rd: R. DeLeo
H. Fansler, H. Smith and J. Segal are down in the hall working on the HRS motion.
16:15 Success in moving the right HRS. It is moving from 44 deg towards 12.5 deg. The group is working on the motion of the Left HRS too.
18:00 target alarm about cryostat. We weren't sure what was going on as the temperatures of the target started to rise uncontrollably.
The incident happened while the Bigbite spectrometer was being moved. Strong rope put by radcon to delimit the perimeter of the radiation controlled area was tied between one of the two vacuum lines leading to the target and the Bigbite spectrometer.
18:30 JP was paged and target heater and fans in both loops were turned off. JT valves were closed, See ELog # 349972
19:00 Cryo group called to mention that they closed ESR supply and return line.
20:20 everybody is out of the Hall except Doug
Vaccum line fixed and pumping started around 20:00
The run coordinator informed us that we won't need a shift crew for the end of the swing shift and the owl shift.
Shift ended at 20:30
