    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.

    Ecm = 500 GeV CLIC ? ? collider based on its drive beam FEL
    (2012) Aksakal H.; Nergiz Z.; Zimmermann F.; Schulte D.; Mikhailichenko A.; Çiftç A.K.
    CLIC is a linear e +e - collider project which employs a drive beam to accelerate the main beam. Various portions of the drive beam provide RF power for corresponding units of the main linac through energy extracting RF structures. CLIC can operate over a wide range of center-of-mass energies, from 150 GeV to 3 TeV. In addition to e +e - collider, ?? and ?e colliders based on CLIC can be realized. In order to generate high energy photons, a Free electron laser (FEL) produced from the CLIC drive beam linac can be used. In this paper we show that the CLIC drive beam parameters satisfy the requirements of the FEL mode of operation. © TÜBI·TAK.

    Luminosity upgrade of CLIC-LHC EP/?P collider
    (2007) Aksakal H.; Çiftçi A.K.; Nergiz Z.; Schulte D.; Zimmermann F.
    An energy frontier or QCD Explorer ?p and collider can be realized by colliding high-energy photons beam, at either 75 GeV or 1.5 TeV, with protons or ions stored in the LHC. In this study we discuss a performance optimization of this type of collider by tailoring the parameters of both CLIC and LHC. An estimate of the ultimately achievable luminosity is given. ©2007 IEEE.
