Bombardment of thin anode foils (gold 10-30 μ thick) by a focused beam of relativistic electrons caused anomalously large heating of the foils, larger by one order of magnitude than the energy input calculated in the single-particle approximation. This effect is attributed to the increased time that the electrons stay in the foil plasma as a result of the action of the magnetic field of the strong-current diode.
