Abstract

1356861 Electron beam irradiation apparatus ENERGY SCIENCES Inc 25 Feb 1972 [16 June 1971] 8881/72 Heading H1D An apparatus for producing a beam of electrons having an elongated cross-section comprises a thermionic cathode 1 surrounded by a channel 3 closed by a control grid 7 which is held negative with respect to the cathode, an electro - static shield structure 11 having a control grid section 13 the function of which is to unify the beam density and a surrounding cylindrical anode 15 having an aluminium electron-pervious window 17 through which electrons pass to irradiate material carried on a conveyer 19.
