Analysis of Multipacting using Field Scaled Particles in VSim

Diana M. Cheatham, Daniel Main, David N. Smithe, Seth Veitzer, Peter Stoltz, Jarrod Leddy, Ilya Zilberter, John R. Cary, "Analysis of Multipacting using Field Scaled Particles in VSim."  This presentation discusses field-scaled particles, which provide a method by which one can study multipacting at multiple values of the electromagnetic power in a single (non-self-consistent)simulation. Field-scaled particles are particles that can selectively respond to field strengths differently. Use of field-scaled particles requires that one have accurate surface fields, and appropriate secondary emission. To illustrate use of field-scaled particles, multipacting computations in both a coax and a spherical cavity are presented, showing that (1) correct surface fields are obtained, and (2) multipacting bands are visible in the simulation. These results are then compared with the more traditional simulation methods. This method is highly efficient and ideal for RF design optimization.
