“…It has been shown in Ref. [2] that the CSR causes 14.5% and 5% growth of the horizontal emittance and of the bunch length, respectively. In order to reduce the impact of the CSR and of the second order effects we propose a modification of the bunch compressor.…”

“…The capture process from the injector into the first superconducting cavity of linac-1 [2], results in bunches having opposite chirp (lower energy at the tail, higher energy at the head). One could use second cavity of linac-1 off-crest to change sign of chirp of bunches and to use chicane type of bunch compressor.…”

“…The schematic view of the facility is given in Fig. 1 and the main electron beam parameters of TARLA are given in Table I [2]. Since generation of FEL requires high peak current with sufficiently small bunch length, especially for shorter wavelengths, TARLA beamline has been designed for minimum bunch length at maximum beam energy.…”

High order and non-linear effects in accelerator beamline play an important role in the transport of the beam. These effects cause variation of designed beam parameters such as emittance growth, bunch length variation, beam halo formation, etc. One of the known non-linear effects in bunch compressors is the coherent synchrotron radiation effect. In this study we focus on coherent synchrotron radiation effect in Turkish Accelerator and Radiation Laboratory in Ankara (TARLA) machine which is designed to drive Infrared Free Electron Laser, covering the range of 3-250 µm. We additionally discuss high order effects in bunch compressor of TARLA.

Abstract:The installation of a high current thermionic gun-based injector capable to accelerate a maximum 1.5 mA electron beam at 250 keV and continuous wave (CW) for various bunch repetition rates has been continuing at the Turkish Accelerator and Radiation Laboratory in Ankara (TARLA) since 2014. The injector, which is based on totally normal conducting technology, will mainly consist of a thermionic DC electron gun, two stage bunch compressor cavities operating at 260 MHz and 1.3 GHz, one dipole magnet, five solenoid lenses and an additional one dipole magnet that is going to be used as spectrometer, and several steerer magnets. In this paper we discuss the design criteria of all magnets of the TARLA injector and present design results.

“…According to operation mode, the bunches will be either compressed or decompressed between 0.4 and 6 ps by using bunch compressor between the two linac modules. The first buncher (sub-harmonic) operates at 260 MHz, the second one operates at the fundamental frequency of LINAC which is 1.3 GHz [3]. TARLA is based on two superconducting electron linear accelerating modules.…”

Turkish Accelerator and Radiation Laboratory in Ankara (TARLA) facility is a superconducting linac-based infrared free-electron laser light source in the frame of Turkish Accelerator Center (TAC). Construction of the facility premises was completed in 2009, with a continued progress of hardware and infrastructure installation until today. In this respect, a button type beam position monitor (BPM) is designed, produced and tested for use of TARLA facility. Antenna simulations and mechanical design studies based on TARLA electron beam parameters are carried out by the software computer simulation technology. In this paper, its design and production highlights are discussed in detail, and the original results are summarized.
