Purpose and Audience
Cryogenic refrigeration process systems are used to support modern particle accelerator superconducting technologies. These are highly energy intensive thermodynamic processes and their reliability directly affects the physics program. They have been misrepresented as off-the-shelf, technically mature systems, when in fact they are high specialized, one-of-a-kind systems, often adapting equipment and processes from other industries due to a lack of development. The purpose of this course is to introduce physicists and engineers who are either involved or interested in these accelerator systems to key cryogenic system technical fundamentals.

Undergraduate courses in thermodynamics, fluid mechanics and heat transfer.

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

Upon completion of this course, students would be expected to:

  1. Identify and understand fundamental fluid-material properties, and thermo-hydraulic aspects important to the design of cryogenic systems
  2. Understand key elements and demonstrate working knowledge in fundamental cryogenic refrigeration cycles, with an ability to apply exergy analysis to a cryogenic refrigeration system
  3. Understand and demonstrate a working knowledge of the characteristics and behavior of key components used in cryogenic systems
  4. Apply the Carnot step analysis to a simple liquefier and refrigerator
  5. Demonstrate a working knowledge of some primary design trade-offs and aspects that lead to an overall optimum efficiency, performance and reliability; and have the ability to model a simple cryogenic refrigeration system and investigate design trade-offs.

Instructional Method
Course will consist of a series of lectures, combined with homework (with worked solutions) to practice reinforce concepts presented and three projects – a design, analysis and modeling project. There will be daily quizzes on material presented previously.

Course Content
The following topics are planned to be covered:

Design, analysis and modeling projects will focus on practical implementation of material presented in lectures.

Reading Requirements
The material for the course will be provided by lecturers. Supplemental text (to be provided by the USPAS) “Cryogenic Systems” (1985) by R.F. Barron.

Credit Requirements
Students will be evaluated on performance in projects (60%) and daily quizzes (40%). Homework is intended to emphasize material in lectures and to help prepare for quizzes.
