Abstract

The Advanced X-ray Astrophysics Facility (AXAF) is one of NASA's 'great observatories' (launch 1998). One of its two focal plane detectors is the High Resolution Camera (HRC) assembly consisting of two microchannel Plate (MCP) based detectors. Key components of the two HRC detectors are UV/Ion shields consisting of metalized sub-micron plastic membranes, designed to prevent UV light and positive ions from reaching the detectors' sensitive surfaces. We discuss results from transmission measurements that have been conducted at the National Synchrotron Light Source (NSLS), on sample plastic membranes and the baseline design HRC-I UV/Ion shield.
