The Physics Society of Iran Iranian Journal of Physics Research 1682-6957 15 2 2019 11 26 Design and construction of a pre-injector for the Iranian Light Source Facility Design and construction of a pre-injector for the Iranian Light Source Facility 183 188 1136 10.18869/acadpub.ijpr.15.2.183 FA A Sadeghipanah KH Sarhadi J Rahighi Journal Article 2019 11 26 Every synchrotron accelerator requires a pre-injector for primary injection of the electrons into the booster ring. The Iranian Light Source Facility (ILSF) pre-injector is a 150 MeV S-band linear accelerator with a thermionic cathode RF gun. The design of the pre-injector lattice and its beam dynamics calculation results together with the design of RF gun, alpha magnet, quadrupole magnets and linear accelerator structures are described in this article. The measurement results of the RF gun prototype fabricated in Iran demonstrate a dimension error less than 20 μm and a surface roughness of less than 0.8 μm Every synchrotron accelerator requires a pre-injector for primary injection of the electrons into the booster ring.
