Investigation of multipactor effect in microwave components in the presence of fringing fields

As part of the EVEREST project of ESA, we implemented in CST Particle Studio™ models of different microwave samples for L- and Ku- bands to investigate the Multipactor effect in the presence of the fringing fields. Using a diversity of Secondary Electron Yield (SEY) data provided from different measurement facilities along with the available ECSS standards, cross validation is examined between the simulation Multipactor results and thresholds achieved by the measurement activity. This study is important in determining the source of inconsistency between both activities. It also provides the possibility to update the existent Multipactor chart for fringing field structures. The convergence studies to acquire accurate numerical results are also presented.
