Evaluation of Particle Loss Due to Multiple Scattering in Foils

Abstract

A graphical integration method is described for the determination of the fraction of a parallel beam of charged particles which is scattered out of a detector when a foil is interposed before the detector. For the case of circular foils and detectors with common normal axes a generalized graph of percentage particle loss is given which illustrates that, although the loss may be quite large, rather small variations of the experimental parameters can greatly reduce it.
