This course will introduce the principles of microwave linear accelerators, starting from Maxwell's Equations and the Lorentz Force Law. The fundamentals of microwave electronics will be covered including waveguide modes, equivalent circuit description, admittance of an iris, coupling of a waveguide to a cavity, and periodic & quasi-periodic structures. The notion of a beam will be introduced, with concepts such as emittance and perveance, and the interaction of a beam with a cavity will be investigated, including beam-loading and wakefields. Beam dynamics from low-energy to high-energy will be explored, from dynamics in guns to linac transport. Additional topics will include a selection from: basic microwave components (directional coupler, matched load, tee, crystal detector, mixer), the strip-line bpm, the cavity bpm, principles of klystrons and modulators, rf pulse compression, beam break-up. Prerequisites: familiarity with calculus and some prior exposure to Maxwell's Equations and the Lorentz Force Law.
