SM/EB-31 Electron Accelerator for Radiation Sterilization and R&D Study Z. Zimek Department of Radiation Chemistry and Technology, Institute of Nuclear Chemistry and Technology, Warsaw,Poland Corresponding Author: zimek@orange.ichtj.waw.pl Upgrading of radiation facility located at Institute of Nuclear Chemistry and Technology in Warsaw has been initiated, with support of IAEA TC Project, towards higher technical and economical effectiveness, better operational characteristics suitable for radiation processing and research programs in order to promote in Poland the radiation technologies for sterilzation medical devices and tissue grafts as well as food product hygenization and other radiation processes where high energy electrons are required. The objective of the project is 10 MeV, 15 kW linear electron accelerator equipped with microwave source based on modern klystron device TH2158 operated at frequency 2856 MHz and standing wave accelerating section. The following stages of the project have been described: electron gun construction, design of microwave system of accelerator including pulse power supply, completion and installation of necessary systems including klystron stand, pulse power supply stand, driving generator stand and waveguide system. The klystron modulator was designed with high power semiconductor HV transistor. Electron beam alignment, beam parameters evaluation and accelerator commissioning are foreseen in the final stage of the project. The better accelerator availability, more stable beam parameters, better spare parts availability, reduced exploitation costs and higher beam power are expected after successful project implementation. Implementation of the project will provide opportunity to develop skills and knowledge of the personnel engaged. It will make also possible to apply the results to another facility in Poland and other central European countries.
