Performance
Scientific paper
superconducting Tunnel junctions (STJs) have been extensively investigated it as photon detectors covering the range from near-infrared to x-ray energies. A 6× 6 array of Tantalum junctions has performed multiple astronomical observations of optical sources using the wiliam Herschel 4.2m telescope at La Palma. Following the success of this programme, we are now developing a second generation camera. The goals of this programme are to increase the field of view of the instrument from “4× 4” to “5×9”, to optimize IR rejection filters, possibly extending the `red' response to ~ lum and to increase the electronics readout speed. For these purposes, we are developing a new Superconducting Tunnel Junction Array consisting of 10× 12 Tantalum/Aluminium devices as well as an important readout system. In this paper, we review the instrument's architecture and describe the performance of the new detector
