Paper Abstract

CUBIC, the Cosmic Unresolved x-ray Background Instrument using CCDs, is instrumented to make non-dispersive spectral observations, with moderate energy resolution over the energy range 200 eV - 10 keV. The CUBIC filter set is designed to attenuate optical and UV photons, with special emphasis on blocking geocoronal lines. To still allow useful soft x-ray transmission, a single thin (1200 angstroms) Al/Ti filter has been designed as the Optical/UV blocking filter. Since the detectors are mechanically collimated, the CUBIC filters are susceptible to pin hole punctures from micrometeoroids. We review some of the LDEF micrometeoroid measurements, and find that while there is good probability that micrometeoroids will transit our filter, the holes will be small enough and few enough in number to have no significant impact on our stray light counting rate.
