System and method for determining charged particle trajectories using a directional particle detector

Abstract

Systems and methods for measuring trajectories of charged particles and for charged particle radiography and charged particle tomography are presented, comprising one or more directional particle detectors (DPDs). A DPD produces a directional measurement of a charged particle by determining the transit distance of the charged particle through a detector medium which is elongated is a single spatial dimension, or by determining the amount of energy deposited by the charged particle in a detector medium which is elongated is a single spatial dimension. Also presented are charged particle transmission imaging systems, charged particle scattering imaging systems, composite DPDs of various geometries, embodiments allowing for the monitoring of a plurality of detector medium columns by as few as one optical sensor, various shapes and compositions of detector medium columns, DPDs elongated in two spatial dimensions, fields of application, and discussions about the fundamental advantages of DPD over coincidence-based charged particle velocimetry.
