A Secondary-Emission Pulse Circuit, Its Analysis and Application

This paper describes a regenerative pulse circuit using a single secondary-emission tube that is able to generate pulses having a rise time of 6 mμsec and a width continuously variable from 25 mμsec to 12 μsec. First, a theoretical discussion of the circuit is given in which expressions for pulse width and rise time are derived. Then, various practical realizations of the circuit are presented. Among others, these include a millimicrosecond pulse generator and a fast pulse height discriminator.
