Paper Abstract

Background in x-ray to in near-Earth orbits from low-energy electrons (<100 keV) has long been a source of concern. Recent data on low-energy electron populations and improvements in the modelling of the propagation of low-energy electrons through grazing-incidence optical systems now allows better quantitative estimates of the electron throughput of such systems to be made. The modelling which has recently been done with respect to the U.K. soft x-ray to (WFC) on ROSAT will be described. The results from the modelling will then be applied to several other missions using grazing-incidence optics and the implications discussed.
