− | == Status == | + | == Status ( updated Sept 12th) == |
− | * The SHMS Calorimeter has been cabled with signal and HV. | + | * Run 82 going for the plus side. Set threshold to 20mV. Moved P14 & P9 from splitter to a linear FI/FO to increase pulse size. |
− | * Have checked setting each channel to 1400V that signal is seen.
| + | * Problems with FADC have been fixed by Brad. The read buffer array was only set for 500 elements when the data was 504 elements. This caused an overflow to the next event. |
− | * 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

| + | *[[ Preshower data cosmic test log 1 | Log of runs 34-71]]. Problem with data readout. |
− | ! Run number !! Start Date/Time !! Trigger !! PreShower Threshold !! Scintillator Threshold !! End Date/Time!! Events !! HV figure !! Comments
| + | *[[ Preshower data cosmic test log 2 | Log of runs 82-present]] . Fix data readout problem. Shifted the FADC window by 80ns so that the ADC signal starts around sample 10 compared to sample 30 before (sample = 4ns). |
