Course:

Vacuum Science and Technology for Accelerator Vacuum Systems

Instructors:

Yulin Li and Xianghong Liu, Cornell Laboratory for Accelerator-Based Sciences and Education



Purpose and Audience
The purpose of this 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 beam accelerator vacuum systems and equipment. This course is suitable for graduate students and senior undergraduate students in experimental or applied physics or students from other fields considering accelerator engineering or physics as a possible career. This course also can provide a broader background to physicists and engineers working in the field of accelerator technology.

Prerequisites
Students with courses in College Physics and/or experience in the vacuum engineering field are preferred, though not essential.

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

Objectives
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. 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 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 14 lectures during the morning and afternoon sessions. Evening sessions will be used for laboratory and homework to enforce the important issues confronting the accelerator vacuum engineer. Problem sets will be assigned during the laboratory sessions with the expectation that they will be completed during those sessions.

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.

Reading Requirements
