Title: Performance of the (n,{gamma})-Based Positron Beam Facility NEPOMUC

Abstract

The in-pile positron source of NEPOMUC at the neutron source Heinz Maier-Leibnitz (FRM II) provides at the experimental site an intense beam of monoenergetic positrons with selectable energy between 15 eV and 3 keV. The principle of the source is based on neutron capture gamma rays produced by cadmium in a beam tube tip close to the reactor core. The gamma ray absorption in platinum produces positrons which are moderated and formed to the beam. An unprecedented beam intensity of 9.10{sup 8} e{sup +}/s is achieved (1 keV). The performance and applications of the facility are presented.
