A new method of electron seeding used for accurate testing of multipactor transients.
A new method of electron seeding used for accurate testing of multipactor transients. D.Raboso,A.wroode European Space Agency, ESTEC, Noordwijk, Netherlands Abstract When testing components for multipactor discharge breakdown it is important to have available sufficient "seed" electrons to initiate the discharge. This is especially important for the multicarrier situation where the addition of all
