A general formalism for treating simultaneously the transverse coupled-bunch and transverse coupled-mode instabilities is presented. In this approach, the equations of motion of a coupled multibunch beam are expanded to yield a system of equations in

The coherent synchrotron radiation (CSR) instability at the shielding threshold may be driven by a single synchronous mode excited by the beam in the beam pipe. The instability in this case has been analyzed [1] in the coasting beam approximation neg

The density and the wake fields of the e-cloud are quite different at low and high beam currents. The wake fields are derived and applied to the upgraded PEP-II B-factory.

Quantum Aspects of Beam Physics.
Quantum theory of the optical stochastic cooling [1] is presented. Consideration follows the evolution of the density matrix of a bunch of particles interacting with radiation in the undulators and quantum amplifier.

The qualitative analysis of the electron cloud formation is presented. Two mechanisms of the cloud formation, generation of jets of primary photo-electrons and thermalization of electrons in the electron cloud, are analyzed and compared with simulati

The coherent synchrotron radiation (CSR) can cause a bunch instability leading to the short wave length density modulation as it was considered in the previous publication [1]. Here, consideration of the problem is refined. The Vlasov equation for th

The wake field of the cloud is derived analytically taking into account the finite size of the cloud and nonlinearity of the electron motion.
