DESIGN, FABRICATION AND COMMISSIONING OF SLOW POSITRON ACCELERATOR AT RADIOCHEMISTRY DIVISION FOR APPLICATIONS IN THIN FILMS

摘要

This paper describes the design, fabrication and commissioning of an automated slow positron beam at Radiochemistry Division, BARC. It has primarily three components, namely, slow positron production, focusing and transport, and acceleration of positrons at the target. The positron energy can be varied from 200 eV to 50.2 keV. The estimated beam size and intensity were ~5 mm and 104 positrons/s respectively. The results of preliminary studies are discussed.
