Partridge Project 16.7 measures the time interval between the primary and secondary reactions in milti-stage devices by direct cecilloscopic reoording of the electromagnetic radiation in the radio frequengy range. In addition, methods of obtaining other diagnos‘ic information from this radiation are investigated. Equipment was operated to attempt to measure alpha, the rate of rise of the puclear reaction. Satisfactory redio silence was obtained, but the signal radiate! does not eppear to fallow alpha.
