Duke PHY745 Section 4, "Special Topics in Accelerator Physics"

Instructors:

Sang-ho Kim and Marc Doleans, Oak Ridge National Laboratory



Purpose and Audience
This one-week course is aimed at accelerator physicists, engineers and technicians who want to learn the principles of Superconducting Linear Accelerators (SCL). Students should have an undergraduate degree in physics or engineering. Particular emphasis will be given on understanding and applying the design concepts to determine and optimize the basic parameters of SCL.

Prerequisites
Undergraduate electricity and magnetism course, undergraduate mechanics course, calculus through differential equations, familiarity with computers.

It is the responsibility of the student to ensure that he or she meets the course prerequisites or has equivalent experience.

Objectives
The course will focus on fundamental principles of superconducting linac and their design. Accelerator theory pertaining to SCL will be presented and applied to the design of several accelerator subsystems. Emphasis will be given to understand the multi-dimensional constraints that govern the design of an SCL and familiarize the students with the iterative process aimed at finding an adequate compromise between the various constraints.

Instructional Method
The course will combine lectures and computer labs with a team approach involving the students. Appropriate software to work through the design of accelerator subsystems that will satisfy a given set of requirements will be provided.

Course Content
The lectures will cover the general principles of SCL including the use of popular computer codes to design and optimize simple SCL, including accelerating lattice and superconducting radio frequency (SRF) accelerating structures. The course will cover basic beam transport theory including the description of beams, beam transport and acceleration and how to apply codes to design an accelerating lattice. The course will also include basic electromagnetics design of SRF cavities, beam loading and other RF interactions in SRF cavities, and general considerations for cryomodules and cryogenics.

Reading Requirements
(to be provided by the USPAS) “RF Linear Accelerators” by Thomas Wangler, Wiley & Sons publishers. The material in the textbook will be used as a reference and will be accompanied by extra material written by the instructors, covering both accelerator theory and support information for the computer codes used in the course.

Credit Requirements
Students will be evaluated based on their performance: 35% homework, 35% computer lab sessions and 30% final exam.
