Center Innovation Fund: GRC CIF
Low-Power, Large-Area Space Radiation Detector
Project Description
The objective of this task is to develop a low-power, large-area detectors from SiC, taking advantage of very low thermal noise characteristics and high radiation tolerance of SiC compared to silicon (Si) devices, and document key characteristics, specifically signal-to-noise, resolution and bias voltage when exposed to 5 MeV alpha particles. We intend to develop, demonstrate, and characterize a large area (200 mm²) detector made from robust HPSI SiC, thus bringing cutting-edge technology to future science missions. The SiC LET detectors will be fabricated as Schottky diodes using micro-fabrication processes. The resulting diodes will be diced and mounted to custom-designed aluminum frames. A 5-MeV alpha particle source will be used for characterization tests.

Anticipated Benefits
Integration into a compact full-field ion detector system on small satellite or other platforms to enable simultaneous 4¹ (spherical) measurements without reliance on spacecraft rotation. Improve understanding of ion flux and energy of solar and cosmic rays in deep space environments (i.e., lunar, planetary, heliophysics).
