| Zusammenfassung | We are developing micro-fabricated x-ray microcalorimeter arrays that show great promise for use in future x-ray spectroscopy missions. In each pixel we sense the magnetization change due to the heat input of an absorbed x-ray using a meander-shaped superconducting pickup trace that is on a substrate that is separate from the low noise 2-stage SQUID read-out. We report on the results from our prototype arrays that have achieved an energy resolution of 3.3 eV at 6 keV, and are progressing future arrays towards the goal of demonstrating sub-eV energy resolution. The results from studies of the thermalization of gold and gold-bismuth absorbers on sub-microsecond timescales will be presented. We will also present the results of comparisons of the magnetization and heat capacity of micro-fabricated devices to those of larger hand-constructed devices. |
