High Current Electron Beam Technologies

Sponsoring University:

Michigan State University

Course Name:

High Current Electron Beam Technologies
This class is limited to 20 students.

Instructors:

Josh Coleman, Los Alamos National Laboratory; Nathaniel J Pogue, Lawrence Livermore National Laboratory; Will Waldron, Lawrence Berkeley National Laboratory

Purpose and Audience
The purpose of this course is to introduce induction accelerator technologies, and the relevant systems involved.  It begins with injector designs and cathode technologies.  Conventional induction accelerators with magnetic cores will be explained in addition to the different pulsed power hardware used to drive injectors and induction cells.   Various design and analysis tools will be presented.  Relevant diagnostic techniques will be discussed as well.    This course is suitable for all education levels from technicians and operators to graduate students in physics and engineering who are interested in induction accelerators as part of their research or career goals.

Prerequisites
Recommend: Undergrad Electricity and Magnetism: level Griffiths, Intro to Electrodynamics (including special relativity)
Recommend: Undergrad Classical Mechanics: level Taylor, Classical Mechanic
Recommend: Undergrad Accelerator Physics: level USPAS Fundamentals of Accelerator Physics
Recommend: Graduate Electricity and Magnetism: level Jackson, Classical Electrodynamics
Recommend: Graduate Classical Mechanics: level Goldstein, Classical Mechanics

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

Objectives
This course introduces the operating technologies of high-current electron induction accelerators including: electron injectors, electron sources, and beam diagnostics.  Pulsed power systems and induction cell technology will also be reviewed.  Accelerator, target, and pulsed power diagnostics will also be discussed.

Instructional Method
Daily lectures will begin in morning sessions and continue through the afternoon.  Daily problem sets will be assigned and expected to be completed outside of scheduled class sessions.  Problem sets will be due the morning of the next lecture session.  The instructors will be available during recitations and evening problems sessions.

Course Content
The course will start with an introduction to induction accelerator technologies and the relevant components required for functionality.  Lectures will start with injector designs and cathode technologies.   Accelerator, pulsed power, and beam physics tools will be presented.  Accelerator and target diagnostics will be discussed with relevant spatial and temporal dynamics, optical and RF techniques, spectrometers, and advanced ideas.  The course will include a lecture on induction accelerator cell and magnet design.  The course will conclude with lectures on pulse power, an overview of systems from low repletion-rate, long- and short-pulse systems to high repletion-rate multi-pulse systems.

Credit Requirements
Students will be evaluated based on: homework assignments (70 % of final grade) and the final exam (30% of final grade).

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 uspas@fnal.gov ASAP to request a laptop loan. Very limited IT support and spare loaner laptops will be available during the session.
