Hi -

Also those electrons can then impact the same surface or another surface as they will be further accelerated by the RF field. As the impact continues to energize, the release of the number of electrons increases which in turn increases the frequency of such impacts, resulting in a sustained multipacation. If this scenario got exponentially elevated it may lead to serious operational problems. In many RF space systems, such multipaction will increase the noise figure and/or bit-error-rate which causes RF signal distortions and can damage the system components or subsystems.
