Scientists, based on the evidence, believe that nearly 4 percent of the universe is visible and the remaining 96 percent consists of dark matter and dark energy. Hereby, the development of the accelerator technology and high energy physics were considered extensively.
ILC is the most powerful of proposed accelerator that is planned to have collision energy of 500GeV initially, with the possibility for a later upgrade to 1000GeV (1 TeV). The most powerful of proposed accelerator that is an alternative for the LHC accelerator is ILC. After being accelerated to the desired energy in a linear accelerator, beam could be transport from the exit of the main linacs to the interaction point. Since we need maximum possibility in the interaction point, beam lines are equipped with electromagnetic multipoles for beam transport and focusing, in such systems. Due to energy loss by beam passing through the electromagnetic multipoles, beam line designing is important to conserve beam energy in beam transport. In this paper, simulation of BDS was done by use of the BDSIM-Geant4 code. Then, beam characteristics were evaluated by use of the some criteria such as emittance. We estimated the distribution of particles at the beginning and end of the BDS line, to find minimum beam size at the interaction point. Finally the amount of energy loss within 100 meters of the lines was studied.
