  A 3-GeV synchrotron light source has been designed as a future light source in Thailand. The storage ring is designed utilising Double Triple Bend Achromat (DTBA) lattice to achieve beam emittance below 1 nm·mrad, maximum beam current of 300 mA and two straight sections per cell. A full energy linac is a promising choice as the storage ring injector due to its potential to be operated as the storage ring injector and an injector for a short pulse facility. The linac can be upgraded to a soft X-ray Free Electron Laser (FEL) facility by extending an undulator section. The design of the linac injector consists of a pre-injector based on a photocathode RF gun, two main linacs based on high gradient S-band structures, and two bunch compressors. The high gradient S-band structure with the accelerating gradient of 35-40 MV/m is suitable to achieve the beam energy of 3 GeV within the injector length of about 150 m. The bunch compressors are included for generating 100-fs electron bunches for the short pulse facility. This paper presents designs and simulation results of the storage ring and the linac injector of Thailand new light source.

  The future synchrotron light facility in Thailand is in designing process, which has a goal to complete a detailed design report in 2018. The new light source will be a ring-based light source with the circumference of approximately 300m and an electron energy of 3GeV. The maximum beam current is 300mA with a beam emittance below 1.0 nm·rad. The accelerator is based on a full energy linac, which will utilize a S-band frequency structures. The RF system of the storage ring is based on 500MHz frequency. The EU-HOM damped cavity and the new SPring-8 design TM020 cavity is the choice of the storage ring cavity. The RF power transmitter can either be a high-power klystron (1 MW klystron) feed all RF cavities or a combination of low power IOTs or solid-state amplifiers feed each cavity. The high gradient S-band structure is considered as the main accelerating structure for linac. The RF power system for linac will base on klystron and a modular modulator. This paper presents details of RF systems options for this new light source project.
