Course Overview

The purpose of this course is to introduce the fundamentals of beam physics via experimental investigation on scaled experiments employing electrons beams. The course is intended for graduate students and advanced undergraduate students who want to familiarize themselves with principles of accelerating charged particles and gain knowledge about contemporary particle accelerators and their applications.

Learning Goals

The course will cover a wide array of the measurements and manipulations that are needed for beam dynamics studies. Upon completion, students are expected to understand the basic principles and relations of beam dynamics, many of which they will have experimentally verified. Furthermore, they will have gained experience in measurement techniques and analysis of experimental observations.

While emphasis will be given on experiments, it will also offer exposure to the latest accelerator computer simulation techniques.

Several major topics will be covered during the semester:

  • source physics
  • magnet measurements
  • optical imaging and processing using both fast and integrating devices
  • phase space mapping and emittance measurement
  • longitudinal dynamics and energy spread, beam control

Overall, students will be exposed to a number of state-of-the-art diagnostics and experimental techniques.

Course Procedure

The course is structured into brief lectures which cover the theoretical background followed by lab sessions. For some experiments, students will be divided into small groups during the lab session that will perform experiments in parallel on different stations. The main experimental stations will be Accelerator Test Facility (ATF) at Brookhaven National Laboratory. Each group will be guided by one or more instructors and ATF staff persons who will assist the students and monitor their performance.

The last two weeks of the semester will be devoted to student presentations. You need to pick a topic and must decide by Mar. 23 in class. Your talk should be planned to take a total of 15 minutes. Five more minutes will be used for questions and comments.

LOCATION: The first class (week 1) will be at Stony Brook University at Chemistry 124. All remaining classes will be at Brookhaven National Laboratory, Building 820.

Textbook and suggested materials

  • “The Theory and Design of Charged Particle Beams” by Martin Reiser, published by Wiley (1994)
  • “Fundamentals of Beam Physics” by James Rosenzweig, published by Oxford 2003
  • “Classical Electrodynamics”, third edition, by J.D. Jackson, published by Wiley (1999). Chapters 11 and 12 are of particular relevance to this course.
  • Accelerator Physics, by S. Y. Lee


Students will be evaluated based on the following performances: class participation (85%) and final presentation on specific research paper (15%). There will be no final exam.

List of topics

The following topics are taken mostly from Physical Review Letters. All topics correspond to breakthrough experiments conducted at the Accelerator Test Facility.
