The energy resolutions of 10eV at 6keV and 32x32 pixels of arrayed x-ray microcalorimeters are required for this purpose. The advantages of x-ray microcalorimeters are clear compared with common x-ray sensors. The most popular x-ray imaging spectrometer is an x-ray CCD. The energy resolution of an x-ray CCD is theoretically limited to ~120eV at 6keV. A grating is usually used as a good energy resolution spectrometer particularly below 1~2eV. However the efficiency of the grating is poor. An x-ray microcalorimeter is fabricated and tested. A superconducting phase transition edge sensor is applied for the x-ray microcalorimeter. The energy resolution of 34 eV at 6keV incident x-ray photon is obtained under 151mk of operating temperature. Details of the x-ray microcalorimeter, signal processing and the latest progress will be presented. |  | View paper | | ISBN: | 0-9728422-0-9 |
