Before began the carbonization process, two cameras were setup in the hotlab for monitoring the evaporator and the power supply. On duty ISAC Ops
also helps to monitor on a regular basis and to grab the striptools + cameras (twice/shift) and put this information in the ISAC Logbook with subject header:
"UCx_2011_A 'date time'", for easy search. |
