    A feasibility study of TAC IR-FEL project
    (ELSEVIER SCIENCE BV, 2010) Aksakal, Huesnue; Arikan, Ertan
    We have performed preliminary simulation of amplifier mode operation of Turkish accelerator complex (TAC) infrared free electron laser (IR-FEL) facility which is designed to operate in oscillator mode. FEL power values of amplifier mode are explored using 3D SIMPLEX 1.3 (X-ray FEL Practical Simulator) simulation code and it is argued that the same or higher amount of power of TAC IR-FEL planing to obtain in the oscillator mode, could be obtained in the amplifier mode, using same undulator and electron beam parameters with a small modification.

    Positron source investigation by using CLIC drive beam for Linac-LHC based e(+) p collider
    (ELSEVIER SCIENCE BV, 2012) Arikan, Ertan; Aksakal, Husnu
    Three different methods which are alternately conventional, Compton backscattering and Undulator based methods employed for the production of positrons. The positrons to be used for e(+) p collisions in a Linac-LHC (Large Hadron Collider) based collider have been studied. The number of produced positrons as a function of drive beam energy and optimum target thickness has been determined. Three different targets have been used as a source investigation which are W-75-Ir-25, W-75-Ta-25, and W-75-Re-25 for three methods. Estimated number of the positrons has been performed with FLUKA simulation code. Then, these produced positrons are used for following Adiabatic matching device (AMD) and capture efficiency is determined. Then e(+) p collider luminosity corresponding to the methods mentioned above have been calculated by CAIN code. (C) 2012 Elsevier B.V. All rights reserved.
