Abstract

The development of hard X-ray focusing optics for astrophysical observation is widely recognized as one of key technologies for future X-ray satellite missions. Utilizing InFOCμS balloon-borne experiment, we have developed thin-foil-nested hard X-ray telescope employing depth-graded Pt/C multilayer. Pre-flight calibration of the hard X-ray telescope for the 2004 flight was performed at X-ray beamline facilities in ISAS/JAXA and SPring-8. The effective area and image quality were estimated to be 51 cm2 and 2.4 arcmin (half power diameter) at 30 keV, respectively. Limiting factors of its performance also investigated. And we revealed that the main factor was image degradation of an individual reflector. Based on such an investigation we are now continuously developing advanced hard X-ray telescope for future balloon experiments. From evaluation of upgraded test telescope, we get a response toward high resolution telescope in future years.
