The design and performance of a new type of ionization gauge, specifically developed for an accelerator, equipped with an ionsource constructed in combination of three electrodes (a hemisphere mesh anode, an annular filament and a funnel-shaped electron reflector) is described. In order to improve the signal-to-noise ratio, the ion current is converted into an alternating current signal by a modulator grid located beneath the ion outlet of the ion source. The new gauge has a sensitivity factor for nitrogen of 14 Torr<SUP>-1</SUP> and a modulation factor of 1.00.
