On the Basic Characteristics of the New Ionization Gauge

Abstract

A new ionization gauge designed to intercept the direct soft X-ray injecting to the ion collector has been tested. It was found that the sensitivity of this gauge was considerably high in comparison with that of the conventional B-A gauge. Collector current vs pressure characteristic war linear over the range of the pressure from 1×10^-9 4×10^-1 Torr. It could be expected that this gauge may be used in the range of XHV.
