In Watertown, Mass., Dynasil Corp.’s research division, !%Radiation Monitoring Devices Inc.%!, has been granted additional US patent claims for its advances in a detector material that responds independently to both neutron and gamma radiation. The current technology for detecting neutrons in homeland security applications – neutron detectors based on gaseous helium-3 – is impractical because the gas has limited availability. Dynasil has developed specialized production furnaces to make the crystals in large volumes, and a high-volume production facility for the crystals and resulting detectors is being installed at the company’s Hilger Crystals Div. in Margate, UK. The Hilger facilities will be ready to supply production volume shipments of the radiation detectors during the third quarter of 2011. Dynasil’s products have applications in medical imaging and other areas.
