ABSTRACT:
Beam deflection apparatus 50 has first and second conductors 64 and 68 positioned transversely in the path of beam 67 and has a resistive connector 78 to be tuned to deflection amplifier 52 and transmission line 54 to provide magnetic deflection. Capacitive plates 74 and 76 are charged by the deflection current to provide substantially equal electrostatic deflection in the same direction.
