Project 6,5 ~ Analysis of Electromagretic Pulse Produced by a Nuclear
Explosion - Charles J, Ong
OBJECTIVE
The objective of Project €.5 was to obtain waveforms of the electromagnetic radiation for all the dctonations during Operation REDWIKC,
This data is to be used in connection with a cortinuing study relating
the waveform parameters to the height and yield of the detonation,
INSTRUMEK TATION
Two identical stations were used to record data, one at Eniwetok
and one at Kwajalein,
The instrumentation consisted of a wide-band receiver with separate
outputs connected to each of the three oscilloscopes,
Mounted on each
oscilloscope was a Polaroid Land Camera for recording the transient
display.
The wide-band receiver consisted of one primary and four secondary
cathode follower amplifiers.
An antenna, frequency insensitive in the
range of interest was fed directly into the prirary cathode follower,
The primary cathode follower was then connected to four individual cethode
followers by a 50-ohm coaxial cable,
Only three secondary cathode
followers were utilized, the fourth serving as a spare.
The number one and two cathode followers fed oscilloscopes with sweep
speeds of approximately 30 microseconds per centimeter and 10 microseconds
per centimeter respectively.
The number three cathode follower was connected
to the third oscilloscope through a 2 microsecond delay line,
