Abstract

An ionization vacuum gauge includes a cathode, an anode and an ion collector. The ion collector component is located at one side of the anode component and spaced from the anode component. The cathode component is located at another side of the anode component and includes an electron emitter, which extends toward the anode component from the cathode component. The electron emitter includes at least one carbon nanotube wire.
