Abstract
1373478 Electron beam apparatus BALZERS PATENT- & BETEILIGUNGS AG 10 April 1973 [26 April 1972] 17093/73 Heading H1D An apparatus for treating an object 14 with an electron beam 1 comprises a cathode 2, a focusing electrode 3 and an anode 12, means being provided for generating a magnetic field 6 to direct the electrons in a curved path to the object 14 and further means for producing a magnetic field perpendicular to the field 6 which can be periodically varied to scan the beam along a direction perpendicular to Fig. 1. The further means can be a single straight conductor 15 or can be a portion of a winding, Figs. 3 and 4 (not shown). In the case of a single conductor this can also form one edge of an anode slit. The field 6 can be produced by a winding or permanent magnet 11 between polepieces 4, (5).
