We present a design study for the Pitch REsolving Spectrometer Electron Transport (PRESET) mission, CubeSat that is aimed at measuring pitch angle density spectrum in low-Earth orbit (LEO). While few missions have measured spectrum, all provided low resolution within loss cone. PRESET will be capable of electrons with 10 degrees or better and an energy range 0.3-7 MeV filling gaps both angular LEO. The spectrometer designed to fit 10x10x10cm 3 volume (1U) including processing electronics so...
Aimed at beta spectrometry and dosimetry for mixed beta-gamma fields, a Si-plastic scintillator coincidence beta-ray spectrometer has been developed. The collects pure spectra by rejecting the gamma-ray detection events through coincidence. Both pulse height arrival time of each event were recorded in list mode compact digital processing system. Spectral measurements carried out using fields from 90Sr/90Y 137Cs sources various gamma count rates to evaluate system performance. spectrum was...
There is a growing demand for precise dose assessment to the lens of eye from beta radiation at CANDU power plants. We present design silicon-based beta-ray dosemeter meet such needs. The primary objective measure in situ fluence rate spectrum and monitor rates eye, skin whole body real-time. aim accomplish minimum gamma rejection ratio 1000:1 avoid overestimation. To achieve objective, features telescopic configuration stack three 40 mm diameter planar Si detectors with different...
