Scattering of coherent light by a cylindrical electron beam

An experimental investigation was made of the scattering of the light from a ruby laser by a cylindrical beam of 1–2 keV electrons of 10⁹–10¹⁰ cm^–3 density. The electron beam was subjected to a longitudinal magnetic field. A time-selective photon counter was used as the detector of the scattered radiation. An investigation was made of head-on and 90° collisions between the laser quanta and the electrons.
