Observational targets of X-ray astronomy are wide-ranging; from planets to super clusters of galaxies. For future X-ray astronomy, a detector is desired to have both eV-level energy resolution and mega-pixel imaging capability. An X-ray microcalorimeter is a detector with the potentiality to satisfy these demands simultaneously. By using a thermistor or a transition edge sensor as a pixel at low temperature (about 100 mK), it has achieved sufficiently high energy resolution. However, since each pixel needs at least a pair of wiring, the heat inflow from a room temperature system through wirings prevents it from attaining high imaging capability. In order to solve this problem, we develop Dielectric X-ray Microcalorimeter (DXMC). We use dielectric, strontium titante (STO), as a material of pixel, and have already detected signals of LED irradiation with DXMC. |
