Hybrid Photodiodes

Electro-optic manufacturer !%Photonis USA%! has announced that it will provide hybrid photodiodes and their power supply units to the Cosmic Ray Energetics and Mass experiment. Conducted by the Cosmic Ray Physics Group from the University of Maryland in College Park, the experiment involves a series of long-duration balloon flights that provide exposure to and measurement of cosmic ray energies to understand their origins. The photodiodes will be used on a calorimeter readout system to measure the energies of ionized cosmic particles.
