a Dibaba (CSAGE) Project 6.5 ~ Analysis of Flectromignetic Pulse Produced by a Nuclear Explosion - C. J. Ong OBITCTIVE The objective of Project 6.5 is to obtain waveforms of the electromagnetic rajiation for all the detonations during Operation REDWING, This data is to be used in connection with a continuing study relating the waveforms parameters to the height ani yield of the detonation, INSTRUMTNTATION Two identical stations are used to record data, one at Fniwetok ani one at Kwajalein. The instrumentation consists of a wide~band reeciver with a separate output connected to each of the three oscilloscopes. Mounted on each oscilloscope is a Polarcii Land Camera for reccrding the transient display. RESULTS tation A = PerryTslani Positive results obtained on fast and medium sweep speed oscilloscopes, The signalsobtained were of good quality. The slow sweep speed oscilloscope dii not trigger and no data were recorded, The predicted fieli strength was 50 volts per meter and the mea- sured field strencth was 26 volts per meter. Station B - Kwajalein The shot time for t (Osege) was delayed and it was imLy COPIED/DOE _ LANL RC tne YY possible to relay this information to Kwajalein in time for this event.
