November 2016 HERMES Outdoor Shot Series 10268-313: Spherical Compton Diodes
- Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)
In November 2016, the High-Energy Radiation Megavolt Electron Source (HERIVIES)-III gamma simulator was used in a series of physics experiments. As part of the environmental characterization, six Spherical Compton Diodes (SCDs) were fielded in order to measure the dose rate at various locations. This report documents the locations, calibration, compensation, and analysis of these sensors. Several short studies are conducted of the SCD signals examining their change with respect to distance, comparison to other sensors and historical data, evaluation of the log-derivative, and signal behavior with a partially obscured converter. Recommendations for future work includes study and extension of SCD bandwidth, characterization of the HERMES-III output spectrum variability, and study of sensor signals with the courtyard shielded from the top of the Magnetically Insulated Transmission Line (MITL).
