Classical Mechanics and Electromagnetism in Accelerator Physics course

Sponsoring University:

University of Texas, Austin

Course:

Classical Mechanics and Electromagnetism in Accelerator Physics

Instructor:

Gregg Penn, Lawrence Berkeley National Laboratory


Purpose and Audience
The course focuses on several topics of classical mechanics and electrodynamics of particular importance for accelerator physics.

Prerequisites

Physics: Upper level undergraduate Classical Mechanics and Electromagnetism.
Mathematics: Multivariate calculus

It is the responsibility of the student to ensure that they meet the course prerequisites or have equivalent experience.

Instructional Method
The two-week course includes lectures in the morning (3 hrs. per class day), and afternoon review and exercise sessions (minimum of 2 hrs. per class day). There will be a final exam at the conclusion of the course.

Course Content
Linear oscillator and resonance. Stochastic force acting on an oscillator. Nonlinear oscillator, dependence of frequency versus amplitude. Nonlinear resonance, parametric resonance, adiabatic invariants. Lagrangian formulation of equations of motion and Hamilton’s equations. Canonical transformations, Liouville’s theorem, and action-angle variables. Extended canonical transformations, Hamiltonian for a circular accelerator, Hill’s equation and betatron functions. Hamiltonian theory of perturbations and nonlinear resonances arising in circular accelerators. Resonance overlapping and transition to stochastic motion. Maps and symplectic integrators. Phase space and the Vlasov equation for the distribution function of a beam, and fluid equations.

Special relativity, Lorentz transformations and Maxwell equations. Self-field of a relativistic beam in vacuum. Electromagnetic interaction of the beam with environment. Examples of numerical computations. Skin effect and the Leontovich boundary condition on the metal surface. Gaussian radiation modes and waveguide fields. Retarded time and the Lienard-Wiechert potentials for radiation processes in electrodynamics. Synchrotron radiation, transition radiation, and diagnostics. Formation length and coherence of radiation. Wake fields, impedances and the Panofsky-Wenzel theorem.

Reading Requirements
