Abstract : The method of analysis described in technical report no. 8 is a pplied to a practical case in which the magnitude of the triggering voltage rises very rapidly to a value sufficient to cut off the initially conducting tube or to raise the grid voltage of the initially nonconducting tube to zero, and in which the duration of the triggering voltage exceeds the time required for equilibium to be established in all parts of the circuit. The plate current of the tube to which the control pulse is applied is assumed to change instantaneously from its 'on' value to zero, or vice versa, and not to change thereafter; the remainder of the triggering process is a transient phenomenon in which this tube does not participate. The analysis indicates that the speed of triggering may be increased by decreasing the tube and circuit capacitances, decreasing the load and coupling resistances in order to reduce the RC time constants, increasing the tube transconductance, increasing positive grid supply voltage, and reducing the range through which the plate and grid voltages change.
