Relativistic charged particle ejection from optical lattice

We have analyzed relativistic (∼ MeV) electron ejection from potential channels of standing laser wave taking into account both rapid and averaged oscillations within the region of declining field of standing wave. We show that only a few last rapid oscillations can define transverse speed and, therefore, angle at which a particle leaves standing wave. This conclusion might drastically simplify numerical simulations of charged particles channeling and accompanying radiation in crossed lasers field. Moreover, it might provide a valuable information for estimation of charged particle beams parameters after their interaction with finite standing wave

On a quantum particle in laser channels

In this paper the effective potential describing interaction of a scalar quantum particle with arbitrary nonuniform laser field is derived for a wide spectrum of the particle energies. The presented method allows to take into account all the features of the effective potential for a scalar particle. The derived expression for effective potential for quantum particle has the same form as the one presented earlier for a classical particle. A special case for channeling of a quantum particle as well as accompanying channeling radiation in a field formed by two crossed plane laser waves is considered. It is shown that relativistic particles moving near the laser channel bottom should be examined as quantum ones at both arbitrarily large longitudinal energies and laser fields of accessible intensities

ANALISIS DE SOLUCIONES TECNICAS PARA EL TRATAMIENTO DE ALTA PRODUCTIVIDAD DE INFORMACION SIMBOLICA

The article examines the current state of the hardware being used in the treatment of symbolic information with a productive approach. It has been shown that the organization of intelligent calculations must be based on the organization of many branched processes controlled by the flow of data, ready for implementation that limits the inherent parallelism itself to the description of the particular task.En el artículo se examina el estado actual del hardware utilizado en el tratamiento de información simbólica con un enfoque productivo. Se ha mostrado que la organización de los cálculos inteligentes debe apoyarse en la organización de muchos procesos ramificados, controlados por el flujo de datos, preparados para la ejecución que permite limitar el paralelismo inherente propio para la descripción de la tarea concreta

Cooling of ultrarelativistic [beta] and [mu] particles by laser channels

The descriprion of ultrarelativistic classical particles' movement in interference laser field formed by multichannel ''sandwich" structures taking into account the radiative energy losses is present. The muon channeling case is described in detail. The critical angle for muon bound motion in the potential well of laser field is defined. The feasibility of beam cooling for charged particles due to radiation losses is shown
