Vacuum Issues

About

Beam dynamics and stability define the requirements on the vacuum static and dynamic pressure inside an accelerator. High intensity beams may however strongly impact the dynamic pressure, through phenomena such as electron cloud, photon and ion induced desorption. The lecture will present these phenomena and mitigation measures that are typically used in particle accelerators. In a second part of the lecture, we will also introduce the direct effect of high-intensity beams on vacuum components, via resistive wall heating or induced resonances, including their effect on the dynamic pressure. This second part will be object of the case study on the next day.
