Development of the RAIDS (Remote Atmospheric and Ionospheric Detector System) Extreme Ultraviolet Wedge and Strip Detector

Abstract

In the next few years the Remote Atmospheric and Ionospheric Detector System (RAIDS) package will be flown on a TRIOS spacecraft. The Extreme Ultraviolet Spectrometer (EUVS) experiment contains a position-sensitive detector based on wedge and strip anode technology. A 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 about 10 to the 7th power. The top MCP is to be coated with MgF for increased quantum efficiency in the range of 500-1150 A. Fabrication of the wedge and strip anode on brazed alumina has presented some challenging problems. In this report, a summary of fabrication techniques and detector performance characteristics is presented. Keywords: Alumina; Kovar. (JHD)
