Assessment  of Silicon Photomultipliers for Miniaturized Radiation Spectrometers for Space  Applications — Radiation  prediction, monitoring, and protection technologies are a key part of all space  missions. The construction of radiation detectors for long-duration exploration  missions presents particular challenges because of stringent size, weight and  power requirements. The proposed work aims to assess silicon  photomultipliers as an enabling technology for miniaturized radiation  spectrometers. These silicon devices have the potential to replace traditional,  bulky photomultiplier tubes, significantly reducing the size and power  consumption of radiation-detection instrumentation with little or no loss of  performance when compared to traditional photomultiplier tubes. Potential  applications of this technology include exploration missions to the Moon and  Mars, stratospheric balloon flights, and small satellite missions, as well as  use in terrestrial fields such as homeland security, law enforcement and health  physics.
