A root cause analysis of REXIS detection efficiency loss during phase E operations
… affected the science output. In this thesis, a root cause investigation is performed on the loss of iron counts, and an optical light leak onto the edge of the instrument's detectors is identified as the most likely cause. A CAST analysis is then performed to identify possible organizational and …
