Revision as of 12:33, 7 August 2012

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
    • type "su" to login as superuser.
    • type "minicom"
  • Listing of the HV setting and cable numbering for the preshower and scintillators
  • Preshower HV for Neg and for Positive side on July 30th at 4:41

Event Data

  • Coincidence data between SHMS Cal and external PMTs Hits per hour
  • Diagram of modules used for collecting coincidence data Module Diagram
  • Voltage versus PMT# plots for the negative and positive sides of the calorimeter. plot
