This Open Access book is drawn from lectures dispensed at the U.S. Particle Accelerator School
(USPAS) Summer 2021 Spin Class by experts in the field. It is an introduction to the dynamics
of spin in charged particle accelerators and to the accelerator components and spin
manipulation techniques including helical snakes and spin rotators which enable and allow
preserving beam polarization. It is aimed at graduate students or upper division undergraduate
students with an interest in this multi-disciplinary field which includes the future
electron-ion collider at the Brookhaven National Laboratory high energy lepton and proton
collider projects and other electric dipole moment search storage rings. It is also aimed at
physicists or engineers working in accelerator-related fields who wish to familiarize
themselves with spin dynamics and polarized beam concepts tools components and purposes.
This is an open access book.
