Phase Stabilized Vernier Chronotron

A 500 channel system is described for measuring time intervals up to 1 μsec in 2 nsec increments. The vernier chronotron method of Lefevre and Russell is modified by the addition of a stable time base which phase‐locks the circulation period of each loop and thus stabilizes the channel width. Solid state circuit elements are used throughout. The application of this time analyzer to the measurement of lifetimes of excited atomic states is discussed.
