The injection line and main ring lattice designs for the University of Maryland Electron Ring [1] have been studied numerically. Possible injection systems were designed using a fitting algorithm based on a set of generalized rms-envelope equations that include the effects of space charge and beam momentum dispersion. The beam dynamics of the injection into and through the periodical ring struc...

Within the framework of the thermal wave model, an investigation is made of the longitudinal dynamics of high-energy charged-particle beams. The model includes the nonlinear self-consistent interaction between the beam and its surroundings in terms of a coupling impedance, and when resistive as well as reactive parts are included, the evolution equation becomes a generalized nonlinear Schröding...

Airy beam, a non-diffracting waveform, has peculiar properties of self-healing and self-acceleration. Due to such unique properties, the Airy beam finds many applications including curved plasma wave-guiding, micro-particle manipulation, optically mediated particle clearing, long distance communication, and nonlinear frequency conversion. However, many of these applications including laser mach...

The proposed future International Linear Collider (ILC) will collide electrons and positrons. Because positrons are antimatter, they are harder to produce than electrons and need to be accumulated and conditioned in a damping ring. The Cornell Electron Storage Ring Test Accelerator (CesrTA) at the Cornell Laboratory for Accelerator-based Sciences and Education (CLASSE) is similar to the damping...

An investigation of the beam-beam interaction as a function of transverse separation of colliding proton and antiproton bunches is presented. A mathematical model describing resonant excitation of separated beams is examined. Beam-beam experiments in the Fermilab collider measure beam-beam resonant excitation ~particle losses! at different transverse beam separations in the storage ring. The ex...

The traditional approach to accelerator optics, based mainly on classical mechanics, is working excellently from the practical point of view. However, from the point of view of curiosity, as well as with a view to explore quantitatively the consequences of possible small quantum corrections to the classical theory, a quantum mechanical formalism of accelerator optics for the Dirac particle is b...

Recent laser technology provides accurate measures of the dynamics of fluids and embedded particles. For instance, the laser-extinction measurements (LEM) uses a laser beam passing across the fluid and measures the residual laser light intensity at the fluid output. The particle concentration is estimated from this measurement. However, the particle flow is submitted to random time-varying fluc...
