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
