The problems of high speed photography are discussed with special reference to the high framing rates mad high sensitivities which can be obtained using image tube cameras. A photoelectronic electron image store and analyser which can be used to overcome the problems of synchronisation is discussed and its constructional details and associated electronic circuitry are described. The shuttering action of the device is analysed in detail in terms of the design of the gating electrode structure and the shape of the applied electrical pulses. The spatial and temporal resolution of the device is discussed. A deflection system is developed so that the device can be operated at a framing rate of ~ 109 f.p.s. using an oscilloscope trace as a simulated event. Synchronisation to the breakdown of a 20 millijoule spark is demonstrated.
