Project 6.5 — Analysis of Electromagnetic Pulse Produced by Nuclear
Beplosion - C, J, Gag
SRDECLIYE
.
The objective of Project 6.5 is to obtain waveforms of the electromagnetic radiation fer all the detonations turing Operation REDWING,
This
data is to be weed in comnection vith a eontinuing stuty relating the
waveforu parameters te the height and yield of the detonatica.
TEENA
Twe identical stations are usel to recor’ date, one at Enivetok and
one at Bajalein.

The inetrunentation consists of « vide-teat receiver with separate
outputs comested te each of the three cpeilloscepes,
Mounted en each
escilicsceps is a Polareid Land Camera for recording the transient ¢is-
play.
The wide-band receiver ecasists of one primary ani four secondary
eathede follower amplifiers.
An extenm, freqesncy insensitive ia the
range of interest is fed directly inte the primary eathode follower,
The primary cathode follower is then connected to four intividesl ea
thede followers ty a SO=ohm coaxial eable.
Only three secondary ea-
thede followers are utilised, the fourth serving a9 & spare.
The mmber one and tvo cathode fellovere feed oseilicesopes vith
oveep speeds of approximately 30 microseconds per centimeter ani 10
microseconis/centineter reapectively, The susber three cathode follever
is commected to the third oscilloscopes through « 2 microsecond delay
line, The third oscilloscope has a sveep speed of 1.0 nicresscenta/
Gentineter.
All cecilloscepes were triggered sigmitaneously ly the
