The pulsed nuclear reactors created at the Joint Institute for Nuclear Research (JINR), with the active participation of I M Frank, is continuously forming a whole series of scientific lines of research in neutron physics. The time-of-flight method in neutron physics consists in neutrons being registered at a given distance L from the source and their time of flight t measured for this distance. Knowledge of L and t permits determining the neutron velocity v and, consequently, its energy. To realize the method, a blinking source is required in order to fix the instant of time when the neutron escapes. In 1965, a microtron was installed as the injector for the IBR reactor; it was constructed at the Institute for Physical Problems (IPP) of the USSR AS. Creation of the pulsed booster-multiplier IBR-30 became the basis for an essential development of neutron nuclear spectroscopy, which at all stages of advancement of neutron physics served as the principal supplier of experimental data.
