The Simulation And Analysis Of The CLIC RTML

During the development of the particle physics, the collider has been proved to be the most efficient way to study the basic components of matter and their properties. In order to improve measurement precision as high as possible, higher energy e+e- col-liders become the most popular colliders now. The Compact Linear Collider(CLIC), which is located at CERN, is an e+e- high-energy collider with a maximum collision energy up to 3 TeV. Because of the limitation of synchrotron radiation at such high ener-gy, CLIC is designed to be a linear collider. In order to achieve the expected collision luminosity, each section of CLIC has to meet a extremely high accuracy requirements. RTML (Ring To the Main Linac) is a subsection of CLIC. In order to check and improve its performance, we use the PLACET[1] software to simulate the RTML.This thesis simulates different beam conditions after RTML affected by the initial z coordinate offset, the RFs’(radio frequency) phase and gradient offset in the BC(bunch compressor) 1, Booster linac and BC2. At the same time, we use linear approximation to analyze the simulation results. According to the simulation results, we design a Feed-Forward system and integrate it into the RTML in the simulation code. With the new simulation, we observe that the Feed-Forward system can relax the tolerance of the RTML.
