XIII International Symposium RREPS-19, 15-20 September 2019, Belgorod, Russia 127Pre-bunched Electron Beam Generation and Applicationfor Accelerator-based THz radiation SourceA.Arysheva,1, D.Yu.Sergeevab,c, L.G.Sukhikhd, A.A.Tishchenkob,c,N.Terunumaa, J.Urakawaaa KEK: High Energy Accelerator Research Organization, Tsukuba, Japanb National Research Nuclear University (MEPhI), Moscow, Russiac National Research Center ”Kurchatov Institute”, Moscow, Russiad Tomsk Polytechnic University, Tomsk, RussiaThe motivation for developing of intense THz source at KEK LUCX is comingfrom the growing interest to THz radiation from various scientific communitiesworldwide. High gradient photo-cathode RF gun and few tens of femtosecond(Ti:Sa) laser system are now routinely used to generate a pre-bunched electronbeam of a few hundred femtoseconds. Also, a new Yb-dopped fiber based lasersystem with enhanced tunability and stability is under development. We areinvestigating the production and properties of the intense radiation beams in therange of 0.1-0.6 THz based on Grating Diffraction Radiation (GDR) and Smith-Purcell radiation. These types of EM radiation are generated when a chargedparticle moves in the vicinity of a periodical pattern or grating. The grating typeand period can be chosen to make quasi-monochromatic radiation spectrum. Inthis reports the status of the KEK LUCX facility and its RF gun laser systemupgrade will be presented. Also, consequent enhancements to radiation studieswill be discussed.This work was supported by the JSPS and RFBR under the Japan-RussiaResearch Cooperative Program (18-52-50002 YaF_a), the Competitivenessenhancement program of Tomsk Polytechnic University and the CompetitivenessProgramme of National Research Nuclear University “MEPhI”.1 Corresponding author: alar@post.kek.jp
