Spatial Sampling for Fast Single Events

A method for observing non-recurrent events having short rise-time has been developed. Signals are sent to a transmission line where 50 sampling gates are tapped. A control pulse triggered by the incoming signal opens simultaneously all the linear gates. Successive tapping points are placed at 200 ps "distance" and the opening time of the gates is a little less. The full event is observed for a period of 10 ns and reproduced with 50 points. At present only 18 points are tapped.
