Upgrading of radiation facility located at Institute of Nuclear Chemistry and Technology in Warsaw equipped with linear electron accelerator towards higher technical and economical effectiveness is being performed to obtain better operational characteristics suitable for radiation processing and research programs in the field of radiation technology development. The objective of the project initiated in 2004 is related to construction of 10 MeV, 15 kW linear electron accelerator equipped with microwave source based on modern klystron device operated at frequency according to European standards and standing wave accelerating section. The project is indispensable in order to promote effectively 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 following stages of the project have been described: 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 semiconductor HV transistor switch was applied in klystron modulator. The standing wave accelerating section has been implemented. Electron beam alignment, beam parameters evaluation and accelerator commissioning will be 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 foreseen in 2007.
