Abstract

Abstract

A novel hard X-ray bent crystal spectrometer, composed of a cylindrically bent crystal, a specula CsI(Tl) scintillator, an image intensifier and a CCD, were proposed, which had the quantitative measurement ability. The details of a quantitative calibration method using X-ray tube and Si(Li) detector was explained. The absolute efficiency of the spectrometer on 17 keV and 19 keV was calibrated using the method. The results indicated that the efficiency on both energy was coherent in dimension. Several issues which might ameliorate the calibration method were discussed.
- transmission bent crystal,
- hard X-ray,
- quantitive calibration,
- absolute efficiency
