Emerging Products

As an active participant in the federal SBIR program, RMD is constantly working to develop new technologies and to improve existing ones. As a result of our ongoing research and development activities, new products regularly emerge. Some of our newest offerings are:

High Performance Gamma Ray Detectors
     RMD has developed gamma ray detectors that have diverse properties, such as high energy resolution, fast response, good linearity and high sensitivity. Imaging designs based on these gamma ray detectors have also been developed for applications demanding high spatial resolution. Other capabilities include excellent timing resolution and high signal-to-noise ratio. These detectors are based on crystals prepared at RMD and fall into two catagories: (i) scintillators, and (ii) semiconductors.

Bright, Fast Scintillators
     RMD has developed bright, fast scintillators based on rare earth trihalide compositions. The scintillators are grown using the Bridgman method and rely on cerium activation to create luminescence. Very high light output (>65,000 photons/MeV), fast decay time (20 ns), excellent proportionality, and high sensitivity can be achieved with these scintillators. Due to these inherent properties, excellent energy resolution (3-4% FWHM at 662 keV) and high timing resolution (~200 ps-FWHM) can be achieved. The scintillators can be used in medical imaging, homeland security, NDE, astronomy, nuclear physics, well-logging and other related applications.

Room Temperature Semiconductors
     RMD has developed new sensors based on compound semiconductors with a bandgap width allowing room temperature operation. High gamma ray sensitivity, good signal-to-noise ratio, low dark current and high conversion efficiency can be expected from these detectors. Pixellated arrays operating in electron-only collection mode have been developed to achieve high energy resolution for X-rays and gamma-rays. These sensors can be applied to medical imaging, homeland security, NDE, astronomy, nuclear physics, nuclear waste cleanup and material science.

Solid State Photomultipliers (SSPM)
     Geiger Photodiode (GPD) pixels are photon-counting Geiger-mode silicon avalanche photodiodes for detecting and digitizing low light-level signals. Solid state photomultipliers (SSPMs) are high-density arrays of GPDs made with inexpensive CMOS technology. SSPMs can provide very high gain, for high sensitivity measurements, as well as the very fast time response needed for a variety of optical and nuclear detector applications

Magnetic Imaging Sensors
     RMD develops and produces solid state magnetic field sensors and sensor arrays made from magnetoresistive materials. The sensors have high sensitivity, low noise and high bandwidth. The sensors can be used to detect and image magnetic field sources associated with defects in metals, electronics and magnetocardiography, among other applications.
