CALIBRATION OF X-RAY SCINTILLATION DETECTORS IN 1-KEV TO 1000-KEV ENERGY RANGE

In the paper, we introduce the sensitivity calibrations of scintillation detectors made of XP1110(or XP1115)multiplier and Nal(T1) scintillator in the energy range of 1-keV to 1000-keV, utilizing direct - current method and X-ray isotope sources and a subkeV X-ray source. The results of calibrations and the corresponding sensitivity curves of XP1110 or XP1115 scintillators assembled with two kinds of NaI Crystals of different thickness at three different high voltage values are given. The sensitivity calibrations of the scintillator in low-energy channel using a proton - induced fluorescence source are also presented.
