Abstract
Space environment is particularly harsh for human activity and human assets. As human activity expands rapidly into space, it becomes ever more urgent to monitor the space environment in situ and in real time. This thesis aims to study a low re-source, miniature detector system to be employed on the satellites to monitor the in-situ space environment particularly for the hazard high energy particles. The vision is that every satellite even at small scale can afford to carry one such detector sys-tem. The core technology used in the detector system is scintillator + SiPM. The scintillator is a mature and traditional radiation detector and the SiPM is the latest generation of photon detector, which rapidly replaces the role of traditional PMT. Development of such detector system requires knowledge over space environment, detector material and geometry, electronics, data processing and more. This thesis tries to have a as complete coverage as possible to demonstrate the flow and the structure of such development. The thesis closely couples the theoretical knowledge to engineering realization. A detector system prototype for pioneering study is fully built and tested from end to end. This serves as the first stepping stone for the path to the full-scale space instrument.
