Measurement of neutron-induced single event transient pulse width narrower than 100ps

A novel SET pulse measurement circuit is proposed which can detect pulses narrower than 100 ps. Alternation of SET pulses during the propagation through the chain of target cells is minimized, which is attributed to small chain length (typically 20). This circuit configuration contributes to obtaining pulse distribution similar to that observed in actual circuit in use. Distribution of SET pulse width measured by our circuit through the white neutron beam testing agrees well with that estimated by computer simulation.
