Definitions

  • the output electrode of the array is normally held at a positive bias potential; the value of this potential depends upon the target material used, but a potential of the order of 10 volts is usually satisfactory.
  • the electrons emerging from the microchannel array have the property that they have sufficient energy to pass the potential barrier between the array and the target and still have sufficient energy to liberate on the average of more than one secondary electron from the target.
  • the secondary electrons are collected by the multiplier array output electrode, to be discussed more in detail in conjunction with the descriptions in FIGS. 3 to 5, thus leaving the target with a positively charged image.
  • This positive charge is capacitively coupled to the opposite side of the target and hence varies the electron scanning beam conventionally utilized to scan the target 14.
