MEASUREMENT OF THE X-RAY SPECTROMETRIC PROPERTIES OF CESIUM HYDROPHTHALATE (CSAP) CRYSTAL WITH THE SYNCHROTRON-RADIATION

The spectrometric properties of several hydrophthalate crystals (KAP, RbAP, TlAP, and CsAP) are studied. Especially investigated is cesium hydrophthalate for which little information is available in the literature. Experimental measurements of rocking curves at 1000 and 2500 eV performed on the SB3 beamline of Super ACO storage ring (LURE-Orsay) are presented. The experimental results are compared with calculations made with a new version of BRAGG, a preprocessor of the ray-tracing SHADOW. This improved version allows to generate rocking curves of any crystal structures. The results of the perfect crystal model matches well with the experimental observation. Among the selected crystals CsAP shows the highest reflectivity. © 1995 American Institute of Physics.
