A POSITRON PRODUCTION EFFICIENCY MEASUREMENT USING THE IAC’S HIGH REPETITION RATE LINAC

Abstract

Positron production efficiency is measured for a positron source that uses a quadrupole triplet system to collect positrons from a tungsten target that are produced when the target is impinged by electrons from the High Repetition Rate Linac (HRRL) at Idaho State University's (ISU) Idaho Accelerator Center (IAC). When a 12 MeV electron beam is used on the tungsten target, positrons escaping from the downstream side of the tungsten with a wide momentum and angular spread. The positrons with spread of 1 to 5 MeV observed experimentally after a 90 degree bend using NaI detectors to detect 511 keV photons from annihilation process. In this talk, the speaker will talk about the experimental setup, procedure and results.
