Abstract

A new version of a streak tube (named SCANCROSS) is proposed, for studies of short light flashes aimed at the elucidation of temporal light flux energy distribution. SCANCROSS differs from the existing streak tubes in that the photoelectrons escaping the photocathode surface are gathered in an aberration-free crossover due to an electrostatic field formed by a 'quasi-spherical' electron-optical system. At the crossover output, the electron beam aperture is compressed, the electron beam accelerates, and is focused on the phosphor screen plane. The two principal advantages of SCANCROSS are a low threshold photosensitivity at preset temporal resolution, and a wide sensing dynamic range.
