systems were used for ten University of California Radiation
Laboratory (UCRL) shots.
Two of the Eniwetok systems served
fifteen Los Alamos Scierntific Laboratory (LASL) shots and
five UCRL shcts.
The third Eniwetok system wae employed on
the two underwater tests conducted by the Department of
Defense.
The B.2xer system detonated the DOD high-altitude
balloon shot.
Tne following signals were se’ecved as standard for tne
hard-wire system;

and voice timing equizment operated properly.
Hard-wire signals were accurate t3 £ 9.05 second with respect
to zero tine.
Radcto signals were delavec anproximately 0.25
second.
The world time clocks recorded tne time of detonation for
29 shots.
The Bhangmeters operated on all but the underwater
shots and recorded the time to light minimum from which an
LAWL RG
early approximation of yield was made on 27 shots.
