In this course we will describe commonly used strategies for the measurement and control of charged particle beams and the manipulation of their properties. Emphasis is placed on relativistic beams in linear accelerators and storage rings. After reviewing beam diagnostics principles, we will discuss basic and advanced beam control techniques aimed towards improving accelerator performance and towards meeting the ever more demanding requirements on beam quality control. These include transverse and longitudinal lattice diagnostics and matching techniques, orbit correction and steering, and linac emittance preservation. Other advanced beam measurements, e.g., related to dynamic aperture and impedance, are considered as well. Techniques for the manipulation of particle beam properties will also be presented, including bunch length and energy compression, bunch rotation, bunch splitting, bunch coalescing, bunch frequency multiplication, changes to the damping partition number in storage rings, and beam collimation issues. The different procedures will be illustrated by examples from various accelerators. Special topics include injection and extraction methods, beam cooling, spin transport, polarization, and the beam-beam interaction. Prerequisite: a course on accelerator physics. Textbook to be provided: "Measurement and Control of Charged Particle Beams" by Michiko Minty and Frank Zimmermann, Springer publishers.
