Abstract

High speed gating with exposure times below 1 ns requires specially modified image intensifier tubes. This contribution deals with such a tube incorporating a dual microchannel plate (ITT F4144 mod.). In connection with a SIT-camera, single photoelectrons can be detected. For gating the tube, special avalanche circuits were developed with pulse width as small as 200 ps (FWHM). The deterioration of the gating pulse by lead inductance and tube capacitance and the attenuation caused by the surface resistance have to be regarded to evaluate the exposure time. As at least the surface resistance of the gating electrodes is unknown, direct measurements are inevitable.
