Overview
This project aims to develop a miniaturized, High-Energy-Resolution relativistic electron Telescope (HERT) that can be easily accommodated into future CubeSat/SmallSat missions to understand and quantify the effect of acceleration mechanism throughout the entire radiation belts to GEO using a novel method of probing electron flux oscillations.
HERT uses a stack of solid-state silicon detectors in a telescope configuration to measure 1-7 MeV electron measurements with an energy resolution (dE/E) <10%.
Principle of Operations
HERT is comprised of a stack of nine solid-state silicon detectors in a telescope configuration with a beryllium window to block lower energy electrons, and a tantalum collimator to enforce the required FOV. Sensor shielding with high-Z materials surrounds the instrument to reduce the amount of radiation exposure at GTO. The final detector in the stack would be used to filter out penetrating particles.
