Abstract
In this paper we present preliminary work on a spatial, arrival time and energy resolving x-ray detector for the study of magnetic reconnection in the solar corona. Our detectors are cryogenic phonon-mediated superconducting Transition-Edge Sensors (TESs). X-rays are incident on a silicon substrate; the generated phonons propagate to the opposite side of the substrate and are absorbed in the tungsten TES electron system. Through a novel spatial distribution of four TESs we aim to achieve simultaneous measurement resolutions of ~10 μm, sub μs, and ~4 eV and with count rates of ~1 kHz. This four TES system is described and preliminary data obtained with a prototype two-channel detector is presented.
