Abstract
A plurality of electron beams are generated by means of cathodes which may be arranged in a circular array and a common target to which the beams are focused. Each of the plurality of electron beams is modulated by the input digital signal (1 or 0) and an enabling signal which is applied in time sequence to the plurality of beams. In this manner the plurality of input signals may be sampled and interleaved to generate a stream of time-multiplexed electron beam digital signals sequentially ordered by the plurality of inputs onto a single diode target. Alternative methods of modulating the electron beam to the target diode may be used. In one method, the source of electrons from a field emission cathode array is modulated. An alternative method utilizes steady sources of electrons in individually focused beams with the current to the diode target being modulated by deflection of the individual beams.
