For this measurement, we used aCdTe X-ray detector(A) with a9 mm active area and a thickness of 1 mm. The detector was placed at the focal point of the polycapillary half lans so that the geometrical collection efficiency of the QMXRs could be 100%. In addition, dependence of the QMXR intensity onthe primary proton intensity was investigated by changing the proton beam current from 0.5 to 2 nA with a proton energy being fixed at 2.5 MeV.
