Abstract

Multipactor charts for parallel plate geometries have been computed using a program that numerically solves a phase equation for the crossing times rather than by detailed computation of electronic paths. Motion in three-dimensional is tracked and detailed models for secondary emission and elastic collisions with the walls are employed. The speed advantage of the method allows the dependence of multipactor prediction on surface properties and multipactor criteria, such as the number of electrons within a shower that are followed, to be assessed over a broad parameter range.

Additional Information:

The avoidance of multipactor is a key issue for the development of vacuum tubes, accelerator cavities and vacuum RF components. The work reported in this paper enables new studies to be carried out on the dependence of multipactor on statistical factors and the inference of secondary emission properties from experimentally determined multipactor thresholds.
