Abstract
A sweep generator circuit generates a primary pulsed voltage and a secondary voltage which are applied to the deflection plates of a streak camera. A primary pulsed voltage generator includes at least one light operated switch for producing deflection of an electron beam in one direction. A secondary voltage generator means generates the secondary voltage which causes deflection of the electron beam in an opposite direction. Variations in the incident light intensity create substantially identical fluctuations in the deflection of the electron beam produced by the primary pulsed voltage and the secondary voltage. Additionally, any variations with respect to time in the deflection of the electron beam produced by the secondary voltage are small in comparison with variations in the deflection of the electron beam produced by the primary pulsed voltage. The sweep generator circuit has an operating point that is stable with respect to variations in the light intensity.
