Abstract :
This paper summarizes our recent achievement on a 10kV vacuum switch with negative electron affinity (NEA) of diamond PIN electron emitters (PIN-emitters), a model for such vacuum switch with PIN-emitters, and a recent progress on reduction of operation voltage of the PIN-emitters with use of hopping conduction of the heavily-doped substrate. These prove a principle of vacuum power switches over 100 kV with an efficiency beyond 99.9%.
