Abstract

In the next few years the Remote Atmospheric and Ionospheric Detector System (RAIDS) package will be flown on a TIROS spacecraft. The Extreme Ultraviolet Spectrometer (EUVS) experiment contains a position-sensitive detector based on wedge and strip anode tech-nology. A University of California Berkeley detector design has been implemented in brazed alumina and kovar to provide a rugged, bakeable housing and anode. A stack of three 80:1 microchannel plates is operated at 3500-4100 V. to achieve a gain of - 10⁷. The top MCP is to be coated with MgF for increased quantum efficiency in the range of 500-1150 Å. Fabrication of the wedge and strip anode on brazed alumina has presented some challenging problems. Below we present a summary of fabrication techniques and detector performance characteristics.
