Single-cycle electron acceleration in focused laser fields.

The possibility of accelerating particles with a focused laser is considered. The particle is accelerated transversely by the electric field and redirected to the forward direction within a single half-cycle by the magnetic field of the radiation. The equations of motion of the particle are solved and discussed. Special attention is given to an intuitive understanding of the constraint imposed by the geometry of the focal region. Optimum conditions are examined.

Io-accelerated electrons and ions

A description is given of a model in which the Jupiter moon Io interacts with the Jovian magnetosphere through plasma sheaths in the vicinity of Io. Several recent results available from Pioneer 10 are used to revise a Io sheath model suggested by Gurnett (1972) and developed by Hubbard et al. (1974). The revised model is used to suggest an explanation for a number of observations. Attention is also given to other phenomena which might be detectable with the aid of future experiments.

Generation and propagation of an electromagnetic pulse in the Trigger experiment and its possible role in electron acceleration

Instruments onboard the Trigger payload detected a large-amplitude, low-frequency, electric field pulse which was observed with a time delay consistent only with an electromagnetic wave. A model for this perturbation is constructed, and the associated field-aligned current is calculated as a function of altitude. This experiment may simulate the acceleration mechanism which results in the formation of auroral arcs, and possibly even other events in cosmic plasmas.
