Abstract:

During the atomic bomb tests on 1948 it became of interest to measure the light intensity from a bomb in the time interval of 0 to 1 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.
