Charged particle beams have diverse applications beyond medical uses, including their role in cathode ray tubes and advanced scientific research. They are crucial for probing fundamental interactions in particle physics, as seen at CERN with large accelerators like the LHC. Additionally, these beams are utilized in synchrotron light sources, free electron lasers, scanning electron microscopes, and security scanners at airports. A contest at CERN invites proposals for experiments using charged particle beams, emphasizing the need for clear communication in inquiries to foster collaboration. Understanding the broader context of charged particle beam applications can lead to innovative experimental ideas.
