Abstract

A feasibility study of an imaging 32 by 32 pixel micro- calorimeter array, intended for the XEUS mission is presented. Three different concepts, theoretically leading to a detector that combines an energy resolution of 5 eV for 8 keV x-rays and a count rate of at least 100 counts/pixel, are presented and discussed. The starting point for this study is the current progress in the field of single pixel micro-calorimeters employing voltage biased transition edge sensors. The design concepts originate from different philosophies for the thermal design and geometrical lay-out and will use state of the art micro-machining and lithography. Moreover, both from an electrical and a cooling point of view SQUID read-out will be the challenge and grouping of pixels might be considered.
