Sponsoring University:

Stony Brook University

Course Name:

Vibrations and Shocks in Operation and Transportation of Accelerator Components

Instructors:

Jeremiah Holzbauer, Brian Hartsell, Adam Wixson, Fermilab

Purpose and Audience
Accelerator components are designed for distinct and unique applications, often quite unlike anything offered commercially. With the lack of industrial experience to draw on and often great expense of prototyping, it’s critical that the design and testing efforts be as robust as possible. This class will cover design and testing of accelerator components in vibrational environments, including stability in operation and surviving the potentially rough shocks of transportation. This class would be appropriate for anyone designing, building, or operating high sensitivity devices (detectors, magnets, cryomodules) or anyone working in an international collaboration-driven project where long-distance transportation of components is inevitable. 

Prerequisites
It is recommended that students applying for this course be familiar with classical mechanics and statics. This class is aimed towards engineers and physicists interested in accelerator components and systems but could also be applicable technicians and operators working on vibration/transportation activities. A strong background in mathematics through calculus, electrical systems especially data acquisition, and familiarity with basic programming will help during data processing and lab sections.  

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

Objectives
The objective of this class is to provide students with the theoretical and practical tools to begin design and testing of accelerator components that either require high stability in operation or must be transported significant distances. This includes design best practices, simulation/calculation methods, validation/testing techniques, vibration instrumentation and data processing, as well as an example of the formal engineering processes established at Fermilab for this topic. 

Instructional Method
This class will be a mix of classroom lectures from different instructors and practical lab sessions including homework and lab reports in the evenings, finishing with a small group project and report.    

Course Content
This class will cover the design considerations of accelerator components’ vibrational stability, including magnets, cryomodules, normal-conducting RF systems, detector systems, and electronics. This includes significant material on resonant structure theory and mitigations, as well as vibration transmission and isolation. Additionally, vulnerable components will be covered such as bellows, ceramics, and composite materials as well as the topics of stress and fatigue. Transportation considerations will be covered as well as the complexities of isolation frames. During these topics, noise sources such as ground motion, fluid flow (water or cryogenic), pump/fan vibration, RF-pulse inducted motion, and road noise during transportation will be discussed. Instrumentation for measuring vibrations in-situ will be covered along with the mathematical tools generally used to analyze the resulting data. The integrated design process developed at Fermilab to integrate these topics into the system design cycles will also be discussed as a model.
