The calculated band gap energy and density of state (DOS). Electronic band structure shows that InAs1-xPx alloys are direct band gap and the optical band gap increase from 0.24 to 1.20 eV with increasing P concentrations. The linear energy dependent dielectric functions and some optical properties such as absorption, energy loss function refractive index and reflectivity calculated. Our results agree well with the available data in the literature.

The system provides information about beam characteristics and enables requested beam parameters to be achieved. The main parameters, such as beam energy, current, emittance, and beam position, must be diagnosed and controlled during the operation of an accelerator. Beam position monitors (BPMs) are an essential tool for diagnosing a system of accelerators. They are used to define the position of the beam traversing through the beam pipe at relativistic speed. These tools can be used to achieve the required beam quality as well as protecting the entire system against any beam loss or radiation damage. In this study, we present the bases of BPM front-end electronics designed for the Turkish accelerator and radiation laboratory (TARLA) facility, which is a linear electron accelerator proposed to drive a free electron laser.

TARLA is proposed to generate oscillator mode FEL in 3-250 microns wavelengths range and Bremsstrahlung radiation. It will consist of normal conducting injector system with 250 keV beam energy and two superconducting RF accelerating modules in order to accelerate the beam 15-40 MeV. The electron beam will be in both continuous wave (CW) and macro pulse (MP) modes. The bunch charge will be limited by 77pC and the average beam current will be 1 mA. To detect electron beam position, BPM (Beam Position Monitor) has to use through beam line. Wall current monitor based system button type TARLA BPM are briefly mentioned. In this study, simulation results of design in CST, production and test studies for button type TARLA BPM are presented. Mechanical and e...
