Abstract

A CCD camera is going to be realized as detector applied to the ALOISA experimental chamber at the ELETTRA synchrotron ring in Trieste, Italy. In this chamber, a high energy monochromatic beam is focused at grazing incidence on a sample to study its surface analyzing the photoelectron diffraction, the scattered and reflected x-ray photons. The aim of this camera is to collect these x-ray photons to determine the position, intensity, and distribution of the diffraction pattern. Moreover, moving the sample, the camera will be able to detect the intensity of the incident beam arriving on the sample from the monochromator. The x-ray photons hit on a P45 phosphor coated faceplate which interfaces the ultra-high vacuum chamber with the detector placed in air. The faceplate is coupled to a taper and then a 512 X 512 pixels CCD collects the visible photons through a fiber optics window. In this paper we describe the design of this detector and report the theoretical evaluation of its performances.
