طراحی کاواک 100 مگاهرتز برای حلقه انبارش چشمه نور ایران

Iranian Light Source Facility (ILSF) RF system was conceptually designed based on ILSF requirements for a 3 GeV storage ring and 400 mA beam current at 500 MHz RF frequency. Considering the fact that  cavity construction is simpler at 100 MHz and advantages of reducing frequency provided an alternative of 100MHz RF system to be explored for ILSF. After a thorough study on the effect of reducing RF frequency on electron beam, machine parameters and comparison of RF systems at both frequencies, the RF frequency was switched to 100 MHz. This paper presents these investigations and comparision leading to selecting the intended frequency. Furthermore, the electromagnetic and mechanical design for 100 MHz cavity are discussed.
