Abstract--Within the framework of a project sponsored by the
European Space Agency (ESA), we have developed a software tool
to predict the occurrence of multipactor discharge in a simple
radio frequency (RF) device modeled as parallel plates. The tool
uses a micro-level explicit representation of the electrons (i.e.,
each electron in the system is modeled separately), and includes
a detailed Monte Carlo model of the secondary electron emission
process in the plates. Materials secondary emission yield (SEY)
is described using either the usual parameter set ( 1, 2, and
max), or a more detailed model, where the contributions due
to true secondary, backscattered or elastically reflected electrons
are given their own sets of parameters, together with additional
parameters for the angle dependence. The simulator has been
validated using experimental data gathered at ESA and the Uni-
versidad Autónoma de Madrid, Madrid, Spain. The simulator
