Very-High-Gain Image-Intensifier Systems and the Photography of Single Photons with Microsecond Time Resolution

A system consisting of image-intensifier tubes in cascade has been used to record photographically the very faint images of high-energy particle tracks in scintillating crystals. This system, currently in use on experiments in high-energy particle physics, is sufficiently sensitive to record single photoelectrons from the first cathode of the system, and capable of a time resolution of a few microseconds. A short time storage allows an electronic gate to be controlled by the event of interest, so that of JO6 events/sec occurring, only that one event of particular interest may be recorded. The image-tube system is described together with a summary of relevant properties of available image tubes and lenses. The limitations due to noise and resolution and the improvements to be anticipated from image tubes are discussed.
