Status

  • The SHMS Calorimeter has been cabled with signal and HV.
  • Have checked setting each channel to 1400V that signal is seen.
  • Altered voltages within SHMS Calorimeter to match around 50 mV per tube.
  • Added external PMT's across top of calorimeter, 6 in total,
  • 06/28 Taking data for number of events through calorimeter and external PMT's
  • 07/10 Added diagram of Modules and Live connections
  • 07/18 Added plots of SHMS Cal. data

Computer Setup

  • Computer is called cnu. The account is gep5.

HV Setup

  • Can control the CAEN 403 through terminal on cnu.
    • Open terminal
