International Radiation Detectors has released the SXUV 100 Ultraviolet/Extreme Ultraviolet (UV/EUV) Photodiode. The photon detector possesses very high radiation hardness and is designed for long-lifetime operation in high particle flux environments with no loss of responsivity.
IRD’s SXUV 100 photodiodes feature 10 x 10mm square active area (100mm²). Diodes with single active areas are available from 1 to 576mm² ; quadrant diodes with several central openings may also be specified. The nitrided metal silicide front window of the SXUV 100 diode permits operation without loss of performance in high humidity and other environmental conditions that normally require sealed packages.
Tested to extraordinary standards, the SXUV 100 photodiode revealed no observable responsivity loss after exposure to billions of 157 and 193nm pulses and exposure to 8 W/cm² of CW 248nm laser irradiance for three weeks.
IRD’s sensor technology devices feature excellent quantum efficiency stability and have been successfully used in both European SOHO and Coronas-Photon projects and in American SNOE, SORCE, GOES, TIMED and EOS solar space instrumentation.
