Beam physics Advanced Course for Nonlinear Dynamics 2 Particle motions in nonlinear fields created by magnets and beam are studied mainly by analytical methods. Nonlinear phenomena of beams such as hysteresis and catastrophe are also covered.
Analysis of Electromagnetic Field of Beams 2 In accelerators, a beam interacts electromagnetically with its surrounding structures such as accelerating cavities and produces electromagnetic fields called wake fields. The wake fields then act back on the beam behavior and may cause an unstable collective motion of the beam. In the present class, I will lecture on the basic of the wake field theory as well as its application, including the numerical computation method of wake fields in the existence of a beam.

Principles of Beam Acceleration 2 Since the invention of cyclotron in 1931, all high energy circular accelerators have employed RFs as accelerating mediums, where standing waves excited in an RF cavity act on charged particles.

Its beam dynamics and key hards will be put in contrast with that of a conventional synchrotron and cyclotron.
