Paper Abstract

The paper has pointed out that the electron transit time dispersion is much worse in the case of the quad tail energy distribution (QTED) typical of x-ray photocathodes in the photo-cathode to mesh region of picosecond image tubes. The temporal abberations of a whole tube have been calculated on condition of a spherical photocathode and concentric a spherical mesh. The paper has put forward a principle of the temporal compensator for the purpose of obtaining the limiting time resolution (about 10-14sec. for the visible light) of image tubes and abolishing the grid mesh which effects seriously the processing of high sensitivity photocathode. It is a electron pulse compressor in essence and has the same action as the mesh.
