Abstract : The authors developed a device for studying the mechanism of electrical breakdown in an ultrahigh vacuum with the aid of high-voltage nanosecond pulses. A preliminary vacuum is achieved by means of zeolite pumps and further evacuation is accomplished with ion sorption pumps. The use of new greaseless pumping materials was occasioned by the fact that oil vapor films coating the electrodes can significantly affect the breakdown mechanism. Pressure was measured with an IM-12 triode ionization manometer. The metalloglass coaxial discharge chamber, with an inner diameter of 60 mm, withstood voltages up to 50 kv and passed pulses with a 1-nsec rise time without distortion. A general view of the device is presented as well as a diagram of the vacuum system, and breakdown initiation is described. (Author)
