Relationship between single-crystal and polycrystal electrical conductivity
The problem of the prediction of the effective electrical conductivity of a polycrystal from the electrical conductivity of a single crystal is considered. It is shown that the familiar Voigt-Reuss bo...

Observations of collective ion acceleration with drifting intense relativistic electron beams
In this paper we report several observations related to the acceleration of positive ions when an intense relativistic electron beam is injected into a low-pressure neutral gas. In addition to varying...

Various aspects of the magnetically self-pinched electron flow patterns in megavolt megampere diodes have been investigated. The onset of pinching has been correlated with a transition from Child-Langmuir to parapotential voltage-current characteristics. The average velocity at which the pinch sweeps towards the axis has been measured and is found to be ~2 mm/nsec. The invariance of the current under geometrical scaling is demonstrated, and the connection between this invariance and plasma motion is discussed. Measurements of total diode current are compared with existing theories and agreement is found with the parapotential model.
