S. R. Mane, +2 more
- 16 Aug 2005 - 
TL;DR: In this paper, a comprehensive survey of spin-polarized beams in high-energy particle accelerators is presented, including work from a number of institutions, including high-and medium-energy facilities, synchrotron light sources and muon storage rings.

Geometric integration for particle accelerators

Étienne Forest
- 12 May 2006 - 
TL;DR: In this article, the authors reconstructed the relevant history of geometrical integration in accelerator physics as much as they could by talking to collaborators and using their own understanding of the field.

Polarized Beams in High-Energy e + e - Storage Rings

Brian William St. Leger Montague
- 01 Nov 1984 - 
TL;DR: In this paper, a balance between these two aspects of the same phenomenon is found to determine the degree of beam polarization that can be built up and maintained in a machine. But the balance between the two aspects is not the same as in this paper.

The first achievement of longitudinal spin polarization in a high energy electron storage ring

D. P. Barber, +21 more
- 19 Jan 1995 - 
TL;DR: A pair of spin rotators has been installed in the electron ring of HERA and up to 65% of the spin polarizations have been reached reproducibly during dedicated measurement time.

Precession of the Polarization of Particles Moving in a Homogeneous Electromagnetic Field

V. Bargmann, +2 more
- 15 May 1959 - 
TL;DR: In this article, the precession of a particle moving in a homogeneous electromagnetic field has been investigated for spin ½ particles in some particular cases and the results were derived by explicit use of the Dirac equation with the occasional inclusion of a Pauli term to account for an anomalous magnetic moment.

Theory of the Alternating-Gradient Synchrotron

Ernest D. Courant, +1 more
- 01 Jan 1958 - 
TL;DR: In this paper, it was shown that if n alternates rapidly between large positive and large negative values, the stability of both radial and vertical oscillations can be greatly increased compared to conventional accelerators in which n is azimuthally constant and must lie between 0 and 1.

On Understanding Spin-Flip Synchrotron Radiation and the Transverse Polarization of Electrons in Storage Rings

John David Jackson
- 01 Jul 1976 - 
TL;DR: In this paper, a discussion of the mechanism for the gradual build up of transverse polarization of electrons and positrons in storage rings is given, and an intuitive explanation of the polarization in terms of spontaneous emission via a nonrelativistic magnetic dipole transition in a moving inertial frame is presented and criticized.

Radiative polarization of electrons in storage rings

V N Baĭer
- 30 Jun 1972 - 
TL;DR: In this article, the probability of a radiative transition in a magnetic field with spin flip was investigated, including the case of a non-uniform magnetic field, and means of suppressing these effects and also of intentional depolarization of a beam were pointed out.

Evaluation of Beam Distribution Parameters in an Electron Storage Ring

Alexander W. Chao
- 01 Feb 1979 - 
TL;DR: In this article, the motion of a charged particle in a linear electromagnetic device can often be analyzed by using the transport matrices, and this technique has been applied to yield fruitful results such as the trajectory of the particle distribution center and the beam sizes and shapes in phase space.
