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
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"
- SHMS Specs
Event Data
- Coincidence data between SHMS Cal and external PMTs
