This class is full. Please contact uspas@fnal.gov to have your name added to the waiting list.

Instructors:

S. Alex Bogacz, Jefferson Lab; Cedric Hernalsteens and Marion Vanwelde, CERN


Purpose and Audience
This course is aimed at providing hands on experience in designing lattices and tailoring beam optics to modern accelerator applications, ranging from simple transfer lines to rings for variety of collider and light source applications. The course will first survey fundamental concepts of beam optics, and then will explore the state-of-the-art areas of modern accelerator design. Typically, a topic first will be discussed abstractly and then applied to a specific beamline.  The course is directed to graduate students pursuing accelerator physics as a career, who want to master the art of lattice design.

Prerequisites
Courses in classical mechanics, electrodynamics, and physical or engineering mathematics, all at entrance graduate level; and the USPAS course ‘Fundamentals of Accelerator Physics & Technology’, or equivalent.

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

Objectives
On completion of this course, the students are expected to harness the principles of particle beam optics and should be able to design a dedicated beamline, tailored for a given accelerator application.

Instructional Method
The course includes a set of introductory lectures followed by practical exercise sessions using interactive lattice design tool, OptiM, http://home.fnal.gov/~ostiguy/OptiM/. After a two-hour tutorial, students should be able to use OptiM for designing simple lattices. Homework projects will be assigned daily, and the results will be graded and discussed in the following sessions.

This course will rely heavily on “OptiM:  A Program for Accelerator Optics” available free here https://uspas.fnal.gov/resources/downloads.shtml. The software runs on the Windows platform.  If you are unable to bring a Windows laptop to the School, please let us know and we will arrange to have a loaner for you.

Course Content
The course will start with a rudimentary FODO lattice description (mostly analytic formulation in a thin lens approximation), then it will discuss basic lattice building blocks, such as: dispersion suppressors, dispersion flips, and finally specialized periodic cells for momentum compaction management and emittance mitigation, as well as lattices with coupling. The course focuses on hands-on experience in designing both rings and transfer lines for variety of collider, booster, and light source applications; e.g. rings with imaginary transition gamma, isochronous, Multiple Bend Achromat, Theoretical Minimum Emittance rings etc. as well as linac optics for multi-pass Recirculating Linac Accelerators and Energy Recovery Linacs

Reading Requirements
Students will receive instructor-provided handouts.  Pre-course reading suggestions include course materials from previous USPAS “Accelerator Fundamentals” (course materials can be found here /materials/materials-table.shtml )

Credit Requirements
Students will be evaluated on homework assignments (70%) and a final project (30%).

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. Students must use a Windows system that is wifi capable and has a standard web browser and mouse . 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.┬áVery limited IT support and spare loaner laptops will be available during the session.
