Neutron Diffraction Study of Amorphous Carbon with a Fast Data Acquisition System

Abstract

A fast neutron data acquisition system involving a curved position-sensitive proportional counter is described. The system permits simultaneous measurement of diffraction data over an angular range of 130 degrees at moderate resolution. Data for amorphous carbon are compared with x-ray diffraction data. Structure functions derived from the different methods are in good agreement. Amorphous carbon is a useful standard for the comparison of diffraction data from different laboratories.
