A linear mode photon-counting (LMPC) detector array in a CubeSat to enable earth science LiDAR measurements

Work is underway to demonstrate a new linear mode photon counting (LMPC) detector in Earth orbit inside a 3U Cubesat. The detector is 16 pixel (2×8) HgCdTe electron Avalanche Photodiode (e-APD) array developed by DRS Technologies, C4ISR Group, Infrared Sensors and Systems (ISS). It has ~70% quantum efficiency and single photon level response at wavelengths from 0.4 to 4 microns. The detector will be mounted in a small integrated detector cooler assembly that operates the e-APD at 80K. The LMPC CubeSat is planned for launch into a 450 km × 820 km × 99 degree inclination orbit in July 2016. In space measurements are planned at 1.06, 1.57 and 2.06 microns using internal sources and with ground-to-space experiments.
