Abstract
The optical transition radiation emitted by electron‐irradiated aluminum, silver, gold‐coated plates, and self‐supported aluminum and Mylar films has been investigated experimentally. The investigation was made with an electron beam incident at 45 °, having a mean intensity of 1 μA, and an energy which was varied from 35 up to 72 MeV (68.5<γ8) which was exploited in the optimization of the phase adjustment of the electron bunches in the accelerating sections of the machine. In such a device using the interference phenomena in transition radiation, the possibility of measurements of the beam energy with a precision of about 1% has also been shown. On the basis of the visibility of fringes, the angular spread of the electron beam and the mean‐square scattering angle in a given material were also estimated.
