Abstract: During the atomic bomb tests in 1948, it became of interest to
measure thalight intensity from a bomb in the time interval of 0 to l
second. The measurement was made from the AV-5 which was at a distance
of 8.9 miles from the explosion. Since no external signal to trigger
the oscilloscope sweep was available, it was necessary to use the light
itself for this purpose, Two scopes were used: one with a linear sweep
length of about 400 microseconds, and the second with an exponential
sweep which was about a second long.

Abstract: This volume describes the nonelectronic equipment necessary to
the Naval Research Laboratory’s participation in Operation Sandstone
and provides a chronology of the project. The subject matter covered
includes: ionization chambers; radiometry equipment used in the
measurement of visible, ultraviolet, and infrared energy; photography
used to record cathode ray tube traces; and transmission lines ~principally from the mechanical point of view.
