Timing System for Firing Widely Spaced Test Nuclear Detonations

Abstract

The national nuclear weapons design laboratories (Los Alamos National Laboratory and Lawrence Livermore National Laboratory) test fire nuclear devices at the Nevada Test Site (NTS), which is spread over an area of over 1200 square miles (a bit larger than the state of Rhode Island). On each test there are hundreds of high time resolution recordings made of nuclear output waveforms and other phenomena. In order to synchronize these recordings with each other, with the nuclear device, and with offsite recordings, there is a requirement that, the permanent command center and the outlying temporary firing sites be time tied to each other and to UTC to permit firing the shot at a predetermined time with an accuracy of about a microsecond. The system is so designed that this can be reduced to about 100 nanoseconds if it should prove necessary in the future.
