Beam Physics

The physics of particle beams has been a broad and vibrant research field encompassing the study of charged particle beams and their interactions. This includes the interaction of particles within the beam, the interaction of beams with the environment and external electromagnetic fields, the interaction of beams with other beams, and finally the interaction of particle beams with beams of electromagnetic radiation. Its foundation is based upon charged particle optics, nonlinear dynamics, and collective effects.


This program is primarily focused on beam theory. There are three main areas of investigation: collective effects, physics of free electron laser (FEL), and beam optics and nonlinear dynamics. The group supports the operating accelerators at SLAC and studies beam physics that can enable or limit future accelerators. Members work closely with other ARD programs.
