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.<BR>It is found that output siguels from the usual 6AH6 fast ionization gauge deviate largely from the electroil beam fluorescence signals.<BR>The deviation may originate from the fact that the head of the fast ionization gauge disturbs the gas flow.<BR>The fast ionization gauge is modified so that the gas can easily flow through the gauge head.<BR>As a result, it is shown that output signals from the modified gauge agree-satisfactorily with the electron beam fluorocence signals.
