For the development of the XR-100 X-Ray Detector, Amptek was honored by R & D Magazine to receive the coveted “R & D 100 Award” for 1994, as one of the year’s most technologically significant products. The XR-100, high resolution x-ray detector, combines a thermoelectrically cooled silicon PIN-Photodiode with an Amptek A250 Charge Sensitive Preamplifier. The unique, all solid state design of the XR-100 eliminates the need to use liquid nitrogen to cool the detector.
