PHYSICS: Colliding Light Beams

Longitudinally Polarized Colliding Beams

The feasibility of experiments with the polarized colliding beams expands significantly possibilities of getting information on fundamental interactions. Even the use of the transversely polarized beams enables getting the more reliable and clear definition of spins for the intermediate states and final particles,1p2 as well as to introduce the precise absolute energy scale.3-s But only the use...

The Equilibrium State of Colliding Electron Beams ∗

We study a nonlinear integral equation that is a necessary condition on the equilibrium phase space distribution function of stored, colliding electron beams. It is analogous to the Ha¨ıssinski equation, being derived from Vlasov-Fokker-Planck theory, but is quite different in form. The equation is analyzed for the case of the Chao-Ruth model of the beam-beam interaction in one degree of freedo...

Integral Equation for the Equilibrium State of Colliding Electron Beams

We study a nonlinear integral equation for the equilbrium phase distribution of stored colliding electron beams. It is analogous to the Haı̈ssinski equation, being derived from Vlasov-Fokker-Planck theory, but is quite different in form. We prove existence of a unique solution, thus the existence of a unique equilibrium state, for sufficiently small current. This is done for the Chao-Ruth model ...

COLLIDING BEAMS: PRESEhy STATUS; AtiD THE SLAC PROJECT*

The field of colliding-beam physics was born in 1958 with the start of construction of the first colliding-beam device by a Princeton-Stanford collaboration. This device, a 2 x 550 MeV electron-electron storage ring, yielded its first results on electron-electron scattering in 1963 and has since been dismantled. However, it spawned a host of more powerful offspring in Western Europe, the USSR, ...
