4 XO (MOHAWK ) Project 6.5 — Analysis of the Electromagnetic Pulse Produced by a Nuclear Explosion - C, J. Ong OBJECTIVE The objective of Project 6.5 is to obtain waveforms of the electromagnetic radiation for all the detonations during Operation REDWING. This data is to be used in conrection with a continuing study relating the waveform parameters to the height and yield of the detonation, INSTRUMENTATION Two identical stations are used to record data, one at Eniwetok and one at Kwajalein, The instrumentation consists of a wide-band receiver with separate outputs conrected to each of the three oscilloscopes, Mounted on each oscilloscope is a Polaroid Land Camera for recording the transient display, RESULTS Station A - Parry Island Data was recorded on two oscilloscopes, The camera shutter on the third oscilloscope did not open and the data was not xecorded. “) Tne predicted field strength was es and the nessured field otrength <0: A The wave form results were not good due to setting the intensities of the trace too high, Staticn B = Kwajalein Data was recorded on all oscilloscopes, a &o The predicted field strength vas Sn) and the measured field strength a \ + analysis, _ gorleD [DDE AADE RE quia X34 The quality of the waveforms were good and should provide easy
