“…Most of the material below is from Sato (1988) and Sato et al (1988). In the Booster, two pulsed quadrupoles were installed to jump the intrinsic resonances, and two pulsed dipoles to correct the closed orbit imperfections.…”

“…This demonstrates that the horizontal betatron oscillations cannot always be ignored during polarized beam acceleration. The resonance strengths in the Booster are tabulated by Sato et al (1988). Because the Booster was a combined-function strong-focusing synchrotron, which included a strong sextupole field component to correct the chromaticity, some depolarization arose from higher order resonances (not reviewed here).…”

Spin-polarized charged particle beams in high-energy accelerators

We present a comprehensive survey of the dynamics of spin-polarized beams in high-energy particle accelerators. A major theme of this review is to clarify the distinction between the properties of an individual particle-a spin-and that of a beam-the polarization. We include work from a number of institutions, including high-and medium-energy facilities, synchrotron light sources and muon storage rings (including a proposal to measure the muon electric dipole moment) and, briefly, linear accelerators and recirculating linacs. High-precision tests of the Standard Model using spin-polarized beams are reviewed; also innovative studies using spin dynamics as a tool for accelerator physics per se. We include important historical works as well as modern developments in the field. The fundamental theory is derived in detail, starting from the basic principles of quantum mechanics, electrodynamics and statistical mechanics, as well as 'accelerator physics'. The principal theoretical formulae in the field (Froissart-Stora, Sokolov-Ternov and Derbenev-Kondratenko) are presented, with in-depth attention to the quantum-statistical mechanics, as opposed to purely 'accelerator physics'.

“…All of the above scenarios still rely on conventional particle accelerators that are typically very large in scale and budget [16] . In circular accelerators, depolarizing spin resonances must be compensated by applying complex correction techniques to maintain the beam's polarization [26][27][28][29][30][31][32] . In linear accelerators, such a reduction of polarization can be neglected due to the very short interaction time between particle bunches and the accelerating fields.…”

The acceleration of polarized electrons, positrons, protons and ions in strong laser and plasma fields is a very attractive option for obtaining polarized beams in the multi-mega-electron volt range. Recently, there has been substantial progress in the understanding of the dominant mechanisms leading to high degrees of polarization, in the numerical modeling of these processes and in their experimental implementation. This review paper presents an overview on the current state of the field, and on the concepts of polarized laser–plasma accelerators and of beam polarimetry.

The acceleration of polarized electrons, positrons, protons and ions in strong laser and plasma fields is a very attractive option to obtain polarized beams in the multi-MeV range. Recently, there has been substantial progress in the understanding of the dominant mechanisms leading to high degrees of polarization, in the numerical modelling of these processes and in their experimental implementation. This review article presents an overview on the current status of the field, on the concepts of polarized laser-plasma accelerators and of the beam polarimetry.
