Abstract

The suppression of secondary electron emission (SEY) which can possibly lead to multipactor is an important goal for several applications. Some techniques have focused on geometric modifications to lower the SEY, though the use of graphene coatings is a promising new development. Here we report on Monte Carlo based numerical studies of SEY on graphene coated copper with comparisons to recent experimental data. Our predicted SEY values are generally is good agreement with reported measurements, with a suppression of about 50 percent for graphene coated copper, especially at the lower energies.
