Project 6.6 ~ Analysis of Electromugnetic Pulse Produced by Nuclear
Explosion - C. J. Ong
ORI PCT IVE
The objective of Project 6.5 is to obtain waveforms of the electromagnetic radiation for 21] the detonations during Operation REDWING.
This
data is to be used in connection 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 instrumcntation consists of a wide-~bani receiver with separate
outputs connected to each of the three oscilloscopes,
Mounted on each **

oscilloscope is a Polaroid Iand Cemera for recortling the transient dis-
cathode follower amplifiers,
An antenna, frequency insensitive in the
range of interest is fed direstly into the primary cathode follower.
The priwary eathsic follower is then connected to four individual ca-~
thode follewers by a 50-chm
ccavial cable.
Only three secondary ca-
thole followers are utilized, the fourth serving as a spare.
The number cne and two cathode followers feed oscilloscopes with
sweep specids of approximately 3° microseconds per centimeter and 10
microsoconis/sentimeter respectively.
The number three cathode follower
is connetted to the third ascilloscope through a 2 microsecond delay
line,
The third oscilloscope has a sweep speed of 1.0 microseconds/
centimoter,
