The Physics Society of Iran Iranian Journal of Physics Research 1682-6957 15 2 2019 11 26 Introduction of design and construction electron linear accelerator project in Institute for Research in Fundamental Sciences(IPM) Introduction of design and construction electron linear accelerator project in Institute for Research in Fundamental Sciences(IPM) 205 213 1139 10.18869/acadpub.ijpr.15.2.205 FA M Lamehi Rashti F Abbasi Davani F Ghasemi H Shaker S Ahmadian Namini Journal Article 2019 11 26 One of the most commonly used types of accelerators is linear electron accelerator. There is a project is in progress in Institute for research in fundamental sciences (IPM) aiming to design and build such an accelerator. It is defined in such a way that all parts to be built in Iran as possibly as it can. In this paper, after a brief explanation of the components of an electron linear accelerator including the electron gun, accelerating tube, RF power supply, vacuum system, waveguide for transmitting RF power to accelerating tube, and cooling system specification of each of these components are presented. The maximum beam energy of 15 MeV and RF pulse power of 2.5 MW with a traveling wave structure at a frequency of 2998 MHz which is acted in π /2 mode are the most important features of this accelerator One of the most commonly used types of accelerators is linear electron accelerator.
