title = "Improvements of the Astro-E2 hard X-Ray Detector (HXD-II)",
abstract = "We summarize significant improvements which have been achived in the development of Astro-E2 Hard X-ray Detector (HXD-II). An expanded energy range and better energy resolution have been achieved from progresses in device materials and re-designing of the front-end electronics. An improved estimation for the detector background in orbit has also been conducted based upon results from our proton irradiation experiment. The sensitivity of HXD-II can be expected to reach an order of 10-6 [c s-1 keV-1 cm-2].",
