A versatile neutron time‐of‐flight spectrometer suitable for use in the millimicrosecond region is described. Either the rf beam deflection method or the gamma coincidence method is used to provide the zero time indication. Details of these methods, along with spectra obtained for some (d,n) reactions, are given. The two systems are compatible and make use of the same simple time‐to‐pulse‐height converter. The dependence of the decay time of a liquid scintillator on the specific ionization of the detected particle has been used to make the neutron detector insensitive to gamma‐rays.
