Description March 24, 1953 - Collimators were used March 24, 1953 for the first time in continental nuclear tests (at Nevada Proving Grounds). This system replaces a more expensive coaxial cable system for recording gamma rays or neutrons. The rays move from a portion of the detonation on the far tower through the line-of-sight holes in successive towers to an underground recording station, covering approximately 4,000 feet of transmission. In the March 24 detonation the detonation tower and portions of the others disappeared, with the remainder being scattered or twisted out of position.
