Paper Abstract

Results are presented on the development of superconducting tunnel junctions suitable as imaging spectrometers for use at extreme ultraviolet (EUV) wavelengths (10 - 100 nm). Progress in improving the spectral resolution of both niobium and tantalum based devices appears such that tunnel limited resolutions (d(lambda) approximately 0.1 nm at 10 nm) should be achievable. In addition these detectors offer not only a high degree of linearity (less than 1%) but a significant efficiency together with a capability to handle rather high count rates. Progress in the development of an imaging instrument through the fabrication of close packed arrays is such that it has become clear that such an imaging spectrometer would represent a powerful and logical next step in the development of instrumentation for EUV astronomy.
