Small-angle X-ray scattering system with linear position-sensitive detector
Abstract
A linear position-sensitive detector has been constructed for use in small-angle X-ray scattering experiments. It is a one dimensional, pressurized gas-filled detector with a delay line read out. Calculated efficiency of the detector at 8.04 keV and 45 psi for ArCH4 filling is 60%, and for Xe-CO2 filling is 90% limited only by the thickness of the entrance beryllium window. Inherent reslution of the detector is 0.1 mm for normal incident X-rays. The overall resolution of the detection system is determined by the width and angular divergencies of the point collimated CU K/sub alpha/ beam used in the experiment. The performance of the system is described in terms of measurements on Al-Zn alloy samples.
