Development of Large-format Photon-counting Array Detectors for the Lyman Ultraviolet Space Telescope

Abstract

This chapter discusses the development of large-format photon-counting array detectors for the Lyman ultraviolet space telescope. The chapter also examines the application of the large-format photon-counting array detector technology developed at Mount Stromlo and Siding Spring Observatories (MSSSO) to the Lyman requirements. The Lyman ultraviolet space telescope requires high-performance photoncounting detectors. The Lyman programme may involve the flight of a grazing-incidence telescope and up to three spectrographs, on a dedicated spacecraft in high Earth orbit. Large-format photon-counting array (LFPCA) detectors are well suited to the programme, and able to provide the required performances. The development of image-tube assemblies, particularly for the prime Rowland spectrographs, is a challenging area. The current detector development programme underway within MSSSO and Auspace Limited gives a high degree of confidence that space-qualified LFPCA detectors can be developed for Lyman within the mission schedule.
