Beam-based Diagnostics class at the USPAS 2006 in Phoenix |
The class on Beam-based Diagnostics was held January 16-20, 2006 at the Embassy Suites Phoenix North, AZ. Course credit for this graduate level course was given by Arizona State University. Lecturers were:
Purpose and Audience
The purpose of this course is to give an overview of beam-based
diagnostics (centered mostly on circular accelerators) including
practical computer examples. The course is intended for graduate
students and postdoctoral fellows, who want to get a start into this
modern and advanced field, as well as for accelerator operators that
want to get a better understanding of advanced measurement methods.
Successful completion of this course carries 1.5 semester hours of ASU
graduate credit. Prerequisites: understanding of basic accelerator physics, electrodynamics and classical mechanics.
Objectives
Charged particle storage rings are used for a variety of science and
technology applications - for example as synchrotron radiation light
sources for biology, chemistry, and materials science, as colliders for
high-energy physics or as damping rings to reduce the beam emittance
for linear colliders. The dynamic aperture limits the performance in
many of these current accelerators. To optimize the performance,
a good knowledge of the machine model is required. To achieve the
required accuracy of the machine model, beam based measurements have
proven to be essential. This course will start with the fundamental
beam dynamics concepts and beam measurement methods and will describe
more and more complex examples of beam-based diagnostics applications
used to understand and optimize machine performance.
Instructional Method
The course will consist of approximately 15 lectures, most of them
during morning sessions. In addition there will be computer classes
every afternoon demonstrating many concepts presented in the lectures
as well as introducing software tools to analyze measurements in the
area of beam-based diagnostics (like orbit response matrices, phase
advance data, etc.). The afternoons will also include some of the
lectures plus some less formal discussion sessions. In addition there
will be 4 homework sets to be solved in the evenings.
Course Content
We will present beam-based methods for characterizing and controlling
the linear and nonlinear optics of a storage ring. We will cover
tune, chromaticity, and dispersion measurement; beam-based alignment;
orbit response matrix analysis; analysis of turn-by-turn orbit data;
beam size measurement; methods of coupling correction; measurement of
dynamic aperture; measurement of energy aperture; characterization of
resonances; tune shift with amplitude; model independent analysis; and
impedance characterization using turn-by-turn and closed orbit
measurements.
