Project 6.5 - Analysis of Electromsgnetic Pulse Produced by Huclesr
Explosion - C. J. Ong
SRIEGTIVE
The objective of Project 6.5 18 to obtain waveforus of the electromagnetic
radiation for all the detonations during Operation REDWING,
This data is to be
used in connection vith a oontinuing study relating the waveform parameters to
the height and yield of the detonation.
AESTRRETATION
Two identical stations are used to record dats, one at Enivetok and one at
Kvajalein,
The instrupentation consists of a vide-bend receiver with seperate outputs
connected to each of the three oscilloscopes.
Mounted on each cecilloseope is
e Polareid Land Camere for recording the transient display.
The wide-band receiver consists of one crimery and four seconiary cathode
follower amplifiers.
An antenna, frecuency insensitive in the rance of
interest is fed directly into the primsry cathode follower,
The primary cathode
follower is then connected to four individual cathode followers by a S-cha
evexial cable.
Only three secondary cathode followers are utilised, the
fourth serving as a spare.
The musber one and two cathode followers feed oscilloscopes with sveer
epeeds of approximately 30 microseconds per centimeter and 10 aicroseconda/
centimeter respectively,
The mmber threo cathode follover is connected to
the third cecillescope through a 2 microsecond delay line.
The third
oeeilicecope has a mveep speed of 1.0 microseconda/centineter.
All
cecilloseopes were triggered simaltaneously by the DC trigger device
