Vacuum Science and Technology for Particle Accelerators


University of New Mexico

Course Name:

Vacuum Science and Technology for Particle Accelerators


Yulin Li, Cornell University/CLASSE and Xianghong Liu, SLAC National Accelerator Lab

Purpose and Audience
The purpose of this graduate-level course is to provide the students with a systematic overview of vacuum science and technology, and applications of the vacuum science and technology to the design and operations of particle accelerator vacuum systems and equipment. This course is suitable for graduate students and last year undergraduate students in experimental or applied physics and engineering fields considering accelerator engineering or physics as a possible career. This course also can provide a broader background to physicists, engineers, and technicians working in the fields of accelerator technology, applications and operations.

Students with courses in College Physics for Scientists and Engineers is required.  Experience with accelerator systems at the level USPAS course “Fundamentals of Accelerator Physics and Technology with Simulations and Measurements Lab” or equivalent is recommended..

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

This introductory course avoids heavy mathematical treatment and will focus on the fundamental principles of the various vacuum pumping concepts available for particle accelerators. Students will be exposed to a variety of materials of construction, methods of fabrication, and preparation and handling techniques. A session on 1D and 3D-simulations of complex high- and ultrahigh-vacuum systems will be given. The course will also cover many design considerations and requirements that are unique to the accelerator vacuum systems. On completion of this course, the students are expected to understand the basic workings of all common types of high-vacuum and ultra-high vacuum pumps. Furthermore, they will understand the various mechanisms of gas sources in accelerators and will be able to calculate gas loads and design vacuum systems to meet accelerator requirements.

Instructional Method
This course includes a series of 9 lectures during the morning and afternoon sessions, including a hands-on session on vacuum simulation using MolFlow+ (https://molflow.web.cern.ch/). Daily problem sets will be assigned for each session to reinforce materials taught in the lectures. One instructor will be available at all times. Some demo vacuum equipment and components will be available during the evenings to give students hands-on experiences.

Course Content
Introductory material will include discussions of vacuum fundamentals, source of gases, materials of construction, and methods of fabrication. The various components that make an accelerator vacuum system such as pumps, bellows, accelerating structures, beam tubes, and instrumentation will be described. In addition, vacuum testing and calculations will be covered.
