Magnetic Micro-Calorimeters: Present success stories, concepts and visions — •Andreas Fleischmann — Heidelberg University, Heidelberg, Germany

Micro-calorimeters are energy dispersive detectors, which can be optimized for the detection of various kinds of particles, ranging from single visible photons over x-ray to hard gamma-rays, including alpha- and beta-particles as well as neutral molecules with some keV of kinetic energy. Operated in a purely thermal mode, micro-calorimeters can achieve arbitrarily good energy resolution, provided a low enough detector temperature. And indeed, in the last decade single channels as well as arrays of micro-calorimeters have become indispensable instruments in numerous fields of science ranging from quantum information, molecular and atomic physics over astro-particle physics to nuclear forensics and homeland security. In this review talk we will present some of the fascinating detector systems, discuss the physics and design considerations of magnetic micro-calorimeters and try to identify promising paths for future developments.
