SECRET (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 Jetonations during Operation REDWIKC. Thie data is to be used in oonrection with « continuing study relating the vavefore parameters to the height and yield of the detonation. TESTRIBEATATION Two identical stations are used to record data, one et Enivetok and one at Evejalein. ‘ The instrumentation consists of a wide-band receiver vith separate outpute connected to each of the three oscilloscopes. Mounted on each oscilloscope is a Polaroid Land Camera for recording the transient display. BESULIS Station A - Parry Island Data was recorded on two ocacilloscopee.
