RMD makes instruments for radiation detection including optical photons, gamma-rays, beta particles, neutrons and protons. The instruments we make range from stand-off gamma and neutron radiation imaging devices, terrestrial and space dosimeters, medical gamma-ray and neutron imaging devices. We utilize existing optical sensors; fabricate custom single photon sensors and arrays of single photon sensors (Solid State Photomultipliers SSPM’s) in commercially existing CMOS processes. RMD’s work is on the edge of technology development to make completely new optical devices in university research laboratories. We are developing devices in Silicon, Silicon Carbide, AlGaAs, InGaAs, and other new semiconductor materials.
