Abstract

We will describe the development of the design and processing of the near ultraviolet (NUV, 1800 - 3000 angstroms) and far ultraviolet (FUV, 1350 - 1800 angstroms) sealed tube microchannel plate cross delay line detectors for the NASA Galaxy Evolution Explorer Satellite. Specifications for the two detector systems for GALEX define a large 65 mm diameter circular format, with high spatial resolution (< 30 micrometers FWHM, approximately 2200 X 2200 resolution elements) and good image linearity (+/- 50 micrometers ), low diffuse background rates of < 1 event cm^-1 sec^-1, and event processing rates of > 2 X 10⁵ events sec^-1. We have implemented a detector design using a microchannel plate Z stack to amplify the signals detected by the photocathodes, and a cross delay line anode to provide the photon event position encoding. These detectors were produced using a new sealed tube production facility installed at the Space Sciences Laboratory, University of California, Berkeley.
