= nyrma) Project 1¢,3 - Electromagnetic Investigations - R. Partridge Project 16,3 measures the time interval between the primary and secondary reactions ir multi-stage Jevices by direct oscilloscopic recorling of the electromagnetic radiation in the radio frequency range. In addition, methods of obtaining other diagrosatic information fron this radiation are investigated, Equipmert vas operated to measure alpha, the rate of rise of the nuclear reaction, Severe radio interference was experienoed, but traces were obtained at reduced sensitivity which appear to be related to alpha. More detaile? readings of these traces will be required. The time interval equipment was operate’, using this device for s dry run, All chanrels operated correctly. BEST AVAILABLE COP’ ae
