ABSTRACT:
An electron collector is shown having four axisymmetric electrodes with off-axis apertures therein which receive an electron beam. The application of a consecutively smaller voltage to each electrode as compared to the cathode that generates the electron beam creates an electrostatic field that efficiently deflects the beam electrons onto the electrodes for their collection.
