摘要

To study the transient response of the fast ionization gauge, the floresconce stimulated by a 23-KV electron beam is usedas a standard gauge for the measurement of time varing density in rarefied gas flow from a fast acting valve.It is found that output siguels from the usual 6AH6 fast ionization gauge deviate largely from the electroil beam fluorescence signals.The deviation may originate from the fact that the head of the fast ionization gauge disturbs the gas flow.The fast ionization gauge is modified so that the gas can easily flow through the gauge head.As a result, it is shown that output signals from the modified gauge agree-satisfactorily with the electron beam fluorocence signals.
