Test and Evaluation of Detector
The test and evolution of QM detector and FM detector were performed using a checkout system. The checkout communicates with the CPM by sending commands from the PC application and receiving telemetry data and user counts. As a part of clearing the environmental tests the command links and data links were verified. The counts without source under different LLD and count settings was observed and recorded as a basis of qualification. The detector was exposed to Radioactive sources like Ba133 (330 keV), Cs137 (660 keV), Eu152 (1112 keV & 1408 keV) for calibration.
