Research into the Accelerating Structure of the LINAC-200 Linear Electron Accelerator

— This paper is devoted to researching the resonant structure of the accelerating sections of the LINAC-200 accelerator in the CST Studio software. A simulation has been carried out for different operating conditions of the structure, i.e., at room temperature ( T = 20°C) and using a thermal stabilization system ( T = 45°C). These results will be needed when setting the temperature regime for accelerator sections.
