    Conceptual design of an X-FEL facility using CLIC X-band accelerating structure
    (Joint Accelerator Conferences Website (JACoW), 2014) Aksoy A.; Yavaş O.; Schulte D.; Latina A.; Wuensch W.; Syratchev I.; Boland M.
    Within last decade a linear accelerating structure with an average loaded gradient of 100 MV/m at 12 GHz has been demonstrated in the CLIC study. Recently, it has been proposed to use the CLIC structure to drive an FEL linac. In contrast to CLIC the linac would be powered by klystrons not by a drive beam. The main advantage of this proposal is achieving the required energies in a very short distance, thus the facility would be rather compact. In this study, we present the conceptual design parameters of a facility which could generate laser photon pulses covering the range of 1-75 Angstrom. Shorter wavelengths could also be reached with slightly increasing the energy. Copyright © 2014 CC-BY-3.0 and by the respective authors.

    Design optimization of an X-band based FEL
    (Joint Accelerator Conferences Website (JACoW), 2016) Aksoy A.; Latina A.; Pfingstner J.; Schulte D.; Nergiz Z.
    A design effort for a new generation of compact, costeffective, power-efficient FEL facilities, based on X-band technology, has been launched. High-frequency X-band acceleration implies strong wakefields, tight alignment and mechanical tolerances, and challenging stability issues. In this paper a design is proposed for the injector and the linacs, including the two bunch compressors. RF gun and injector simulations have been performed, successfully meeting the stringent requirements in terms of minimum projected emittance, sliced emittance and minimum bunch length. In the design of the linac and bunch compressors wakefield effects and misalignment have been taken into account. Start-toend tracking simulations through the optimized lattice are presented and discussed. Copyright © 2016 CC-BY-3.0 and by the respective authors.

    Diagnostic system of TAC IR FEL facility
    (2011) Nergiz Z.; Aksoy A.; Ozkorucuklu S.; Ceylan S.; Kaya C.
    The TAC (Turkish Accelerator Center) IR FEL facility which is named as Turkish Accelerator and Radiation Laboratory at Ankara, TARLA will be based on a 15-40 MeV electron linac accompanying two different undulators with 2.5 cm and 9 cm periods in order to obtain IR FEL ranging between 2-250 microns. The electron linac will consist of two sequenced modules, each housing two 9-cell superconducting TESLA cavities for cw operation. It is planned that the TARLA facility will be will be completed in 2013 at Golbasi campus of Ankara University. This facility will give an opportunity to the scientists and industry to use FEL in research and development in Turkey and our region. In this study, the main structure of the facility and planned electron beam diagnostics system is given in detail.

    FEL proposal based on CLIC X-band structure
    (Joint Accelerator Conferences Website (JACoW), 2014) Aksoy A.; Yavas Ö.; Schulte D.; Latina A.; Wuensch W.; Grudiev A.; Boland M.J.
    A linear accelerating structure with an average loaded gradient of 100 MV/m at X-Band frequencies has been demonstrated in the CLIC study. Recently, it has been proposed to use this structure to drive an FEL linac. In contrast to CLIC the linac would be powered by klystrons not by an RF source created by a drive beam. The main advantage of this proposal is achieving the required energies in a very short distance, thus the facility would be rather compact. In this study, we present the structure choice and conceptual design parameters of a facility which could generate laser photon pulses below Angstrom. Shorter wavelengths can also be reached with slightly increasing the energy.

    The status of TAC IR FEL and bremsstrahlung project
    (2010) Aksoy A.; Yavaş O.; Zengin K.; Ozkorucuklu S.; Tapan I.; Duran Yildiz H.; Arikan P.
    Turkish Accelerator Center Infrared Free Electron Laser and Bremsstrahlung (TAC IR FEL&Brems.) project aims to produce cw mode FEL in 2.5-250 microns range and to produce bremsstrahlung photons using 15-40 MeV electron beam. The project is supported by State Planning Organization (SPO) of Turkey and is proceeded with inter university collaboration under the coordination of Ankara University. This facility is now called Turkish Accelerator and Radiation Laboratory at Ankara (TARLA) since its building located at Golbasi town 15 km south of Ankara, Turkey. It is proposed that the facility will consist of 300 keV thermionic DC gun, two superconducting RF module and two optical resonator systems with 25 and 90 mm period lengths. In this study, the status and road map of the project is presented including some technical details on accelerator and FEL. In addition the research potential of facility is summarized.

    The TAC IR FEL oscillator facility project
    (2009) Ketenoglu B.; Aksoy A.; Yavas O.; Tural M.; Karsli O.; Ozkorucuklu S.; Tapan I.
    The TAC (Turkish Accelerator Center) IR FEL Oscillator facility, which has been supported by Turkish State Planning Organization (SPO) since 2006, will be based on a 15-40 MeV electron linac accompanying two different undulators with 2.5 cm and 9 cm periods in order to obtain IR FEL ranging between 2-250 microns. The electron linac will consist of two sequenced modules, each housing two 9-cell superconducting TESLA cavities for cw operation. It is planned that the TAC IR FEL facility will be completed in 2012 at Gölbasi campus of Ankara University. This facility will give an opportunity to the scientists and industry to use FEL in research and development in Turkey and our region. In this study, the results of optimization studies and present plans about construction process of the facility are presented.

    Turkish accelerator center: The status and road map
    (Joint Accelerator Conferences Website (JACoW), 2014) Aksoy A.; Cakir O.; Duran Yildiz H.; Yavas O.; Akkus B.; Ozkorucuklu S.; Algin E.
    Turkish Accelerator Center (TAC) Project has started with support of the Ministry of Development (MD) of Turkey under the coordination of Ankara University. TAC is an inter-university collaboration with 12 Turkish Universities. An IR FEL facility (TARLA) based on Sc linac with 15-40 MeV energy under construction in Ankara as the first facility of TAC. It is expected that the TARLA facility will be commissioned in 2017. In addition to the TARLA, it is planned that Turkish Accelerator Center will include a third generation synchrotron radiation facility based on 3 GeV electron synchrotron (TAC SR), a fourth generation SASE FEL facility based on 3 GeV electron linac (TAC SASE FEL), a multi-purpose proton accelerator facility with 3 MeV - 2 GeV beam energy (TAC PAF) and an electron-positron collider as a super charm factory (TAC PF) Construction phase of the proposed GeV scale accelerator facilities will cover next decades. In this presentation, main goals and road map of Turkish Accelerator Center will be explained. Copyright © 2014 CC-BY-3.0 and by the respective authors.
