Description
We present current results of electromagnetic calculations of the interaction of a high-intensity beam field with the metallic walls of the FCC-ee vacuum chamber of the Interaction Region. This interaction creates a thermal load on the beam pipe walls, which leads to the destruction of vacuum conditions and a possible increase in background. We calculated the thermal load for the proposed materials used in the mechanical design and analyzed how coating the beam tube with other materials can reduce the thermal load or improve vacuum conditions. We performed calculations using FCC-ee beam parameters for different energies Z, WW, H(ZH) and ttbar.
