Abstract:

The pulsed radiation environment of the proposed Satellite X-Ray Test Facility SXTF consists of synchronized pulses of low-energy plasma radiation and bremsstrahlung produced by 150-keV electrons. In addition, there is also a low level, steady spray of 1-MeV electrons. In the experiments reported here, pulsed irradiation was performed by using the Harry Diamond Laboratories FX-45 in the bremsstrahlung mode, and the steady state irradiation was performed by using a 60Co source. The SXTF fiber has to carry an analog signal during the radiation pulse with negligible distortion due to transient darkening or Cerenkov radiation. Several fibers were tested, and the IVPO fiber was found to be the best because it has very little transient darkening. Cerenkov radiation was effectively removed from all transmitted signals by using narrow optical bandpass filters. Author
