Abstract

The operation of high-energy and high-intensity particle accelerators inevitably leads to the loss of a fraction of beam particles, either through controlled processes or accidental events. This article builds on a first lecture on particle-matter interactions to review the main beam loss mechanisms in high-energy and high-intensity accelerators and their implications for safe and efficient operation. It discusses the resulting risks of equipment and material damage, radiation effects on electronics, and radiation-protection hazards. The focus is on beam losses in hadron accelerators, with particular emphasis on the Large Hadron Collider at CERN, while also addressing proposed future facilities such as the Future Circular Collider and muon colliders.
