A multi-radiation Generator system based on a 15 MeV Electron Linear Accelerator
semanticscholar(2019)
Abstract
Most radiation generating equipment have been developed for the purpose of generating one radiation in one device. In particular, it has been difficult to generate various types of radiation due to various constraints in industrial and medical purpose radiation generating devices, except large research facilities utilizing energy of several tens MeV or more. Recently, however, radiation has been utilized in various fields such as defense, medical, and basic science, and the field of radiation is becoming wider, so that the efficiency of the radiation generating apparatus becomes increasingly important [1]. In this study, we have constructed a system capable of generating three kinds of radiation in one device. The device, designed to produce neutrons, X-rays and electron beams through a single generator, was developed on the basis of a 15 MeV electron accelerator which is manufactured by KAERI. In order to control the generation of each radiation as desired by the operator, a rotating target synchronized with the RF system was installed in the beam exit of the electron accelerator. The design specification for this facility, which has just been constructed, is above 30 Gy/min at a distance of 1 m from the target for X-ray dose rate and the targeted neutron generation rate is above 10 n/s. The results of this study will be used mainly in the field of basic science such as physics, chemistry, and biology in the future, and it can be applied to fields such as security search and medical care.
