    Ion dynamics in a Paul trap driven by various radio frequency waveforms
    (ELSEVIER SCIENCE BV, 2016) Aksakal, Husnu
    In this study we explore single ion dynamics in a Paul trap (three-dimensional radio frequency (RF) quadrupole ion trap - 3D QIT), driven by Sinusoidal, Rectangular, Sawtooth and Triangular RF waveforms. A molecular dynamic simulation code in Python has been written to explore ion dynamics in the trap. It is shown that various radio frequency waveforms produce various shift in ion oscillation in the trap. Furthermore phase space plots and the magnitude of the potential well depth for these various waveforms are given. Possible influences of these various RF waveforms have been summarized.

    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.
