Abstract
A 12 MeV linear accelerator is currently used for electron beam proces sing of power semiconductor devices for lifetime control and, on an ex perimental basis, for food irradiation, sludge treatment etc. In order to control tbe irradiation process a simple, quick and reliable metho d for a direct evaluation of dose and fluence in a broad electron beam has been developed. This paper presents the results obtained using a 'charge collector' which measures the charge absorbed in a graphite ta rget exposed in air. Calibration of the system with super-Fricke dosim eter and comparison of absorbed dose results obtained with plastic dos imeters and alanine pellets are discussed.
