Abstract

In designing high-speed time-resolving image converter tubes (ICT) it is necessary to estimate beforehand the time resolution of the image converter system (ICS) to be employed. To obtain a correct estimate one must take into account the spreading of converged electron beam in the ICS due, first, to the scatter of the initial longitudinal velocity of electrons /I, 2/, second, to the scatter of the initial transverse velocity of electrons and the finite dimensions of the photocathode image (i.e., dut to different electron path deflections from the axis) /3/ and, third, to the electrostatic (Coulomb) interactions between electrons in the converged beam /4-6/. In /4, 5/ the focusing effect, which en-hances the interactions of electrons was not taken into acount; in /6/ the calculation were obtained with the help of computer.
