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.More »
Integration into a compact full-field ion detector system on small satellite or other platforms to enable simultaneous 4π (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).More »
