Purpose and Audience
This one-week graduate-level course is aimed at accelerator physicists and engineers who want to learn the principles of Superconducting Linear Accelerators (SCL). Emphasis will be given on understanding and applying design concepts to determine and optimize basic parameters of SCLs for a variety of applications.
Undergraduate electricity and magnetism, undergraduate mechanics, linear algebra and differential equations, familiarity with computers.
It is the responsibility of the student to ensure that they meet the course prerequisites or have equivalent experience.
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. At completion of the course, students should be able to carry out the basic conceptual design of a SCL.
The course will combine morning lectures, afternoon computer labs followed by daily homework assignment. Appropriate software to work through the design of accelerator subsystems will be provided.
The lectures will cover the general principles of SCL including the use of popular computer codes (SUPERFISH* and TRACE3D**) to design and optimize simple SCLs, 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 accelerator 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.

(to be provided by the USPAS) “RF Linear Accelerators” (second edition) 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 tutorials for the computer codes used in the course.
Credit is based on exercises given in seven homeworks, one midterm, and one final exam. Each part of each exercise carries a weight of at least one point, and more difficult exercises will carry up to 4 points. Points for the course usually total about 150, with typically 20 points each for midterm and final. Extra credit opportunities will appear frequently.
USPAS Computer Requirements
There will be no Computer Lab and all participants are required to bring their own portable computer to access online course notes and computer resources. This can be a laptop or a tablet with a sufficiently large screen and keyboard. Windows, Mac, and Linux-based systems that are wifi capable and have a standard web browser and mouse are all acceptable. You should have privileges for software installs. If you are unable to bring a computer, please contact firstname.lastname@example.org ASAP to request a laptop loan. Very limited IT support and spare loaner laptops will be available during the session.
