Positron source investigation by using CLIC drive beam for Linac-LHC based collider

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.
