Öğe Accelerator based light source projects of Turkey(Joint Accelerator Conferences Website (JACoW), 2016) Aksoy, A.; Karsli, Ö.; Kaya, Ç.; Yavaş, Ö.; Keteno?lu, B.; Nergiz, Z.Three light source project is ongoing in Turkey within the frame of Turkish Accelerator Center (TAC) Project which has been supported by Ministry of Development since 2006. As a first facility of TAC, 3-250 ?m IR-FEL facility (TARLA) based on superconducting accelerator with an energy of maximum 40 MeV is under construction at Institute of Accelerator Technologies of Ankara University. In addition to TARLA, Conceptual/Technical Design Report of a third generation synchrotron radiation facility based on 3 GeV, and a fourth generation FEL facility based 1-6 GeV is being prepared for the next steps of TAC. Therewithal a proton accelerator facility with up 2 GeV and an electronpositron collider as a super charm factory are proposed within the frame of TAC project. In this presentation, current status of TARLA project and main goals, road map of Turkish Light Sources will be explained.

S.; Aksoy, A.; Zhou, D.; Zimmermann, F.; Aksakal, H.The Large Hadron electron Collider (LHeC) is a proposed future particle-physics project colliding 60 GeV electrons from a six-pass recirculating energy-recovery linac (ERL) with 7 TeV protons stored in the LHC. The ERL technology allows for much higher beam current and, therefore, higher luminosity than a traditional linac. The high-current, high-energy electron beam can also be used to drive a free electron laser (FEL). In this study, we investigate the performance of an LHeC-based FEL, operated in the self-amplified spontaneous emission mode using electron beams after one or two turns, with beam energies of, e.g., 10, 20, 30 and 40 GeV, and aim at producing x-ray pulses at wavelengths ranging from 8 to 0.5 angstrom. In addition, we explore a possible path to use the 40 GeV electron beam for generating photon pulses at much lower wavelengths, down to a few picometer. We demonstrate that such ERL-based high-energy FEL would have the potential to provide orders of magnitude higher average brilliance at angstrom wavelengths than any other FEL either existing or proposed. It might also allow a pioneering step into the picometer wavelength regime.Öğe Conversion efficiency and luminosity for gamma-proton colliders based on the LHC-CLIC or LHC-ILC QCD explorer scheme(ELSEVIER SCIENCE BV, 2007) Aksakal, H.; Ciftci, A. K.; Nergiz, Z.; Schulte, D.; Zimmermann, F.Gamma-proton collisions allow unprecedented investigations of the low x and high Q(2) regions in quantum chromodynamics. In this paper, we investigate the luminosity for "ILC" x LHC(root s(ep) = 1.3 TeV) and "CLIC" x LHC(root s(ep) = 1.45 TeV) based gamma p colliders. Also we determine the laser properties required for high conversion efficiency. (C) 2007 Elsevier B.V.

The first stage of the project is to construct an Infra-Red Free Electron Laser (IR-FEL) facility. The second stage is to build a synchrotron radiation facility named TURKAY, which is a third generation synchrotron radiation light source that aims to achieve a high brilliance photon beam from a low emittance electron beam at 3 GeV. The electron beam parameters are highly dependent on the magnetic lattice of the storage ring. In this paper a low emittance storage ring for TURKAY is proposed and the beam dynamic properties of the magnetic lattice are investigated.Öğe Luminosity upgrade of CLIC-LHC ep/gamma p collioder(IEEE, 2007) Aksakal, H.; Ciftci, A. K.; Nergiz, Z.; Schulte, D.; Zimmermann, F.An energy frontier or QCD Explorer ep and gamma p collider can be realized by colliding high-energy photons generated by Compton backscattered off a CLIC electron 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.
