Test ban compliance: is seismology enough
The treaties under debate were signed more than a decade ago: the Threshold Test Ban Treaty (TTBT) by President Nixon in 1974 and the Peaceful Nuclear Explosions Treaty (PNET) by President Ford in 1976. Between them, they prohibit all underground nuclear blasts with an explosive yield greater than 150 kilotons. When negotiated, verification of the testing agreements was entrusted to seismology, but the remote seismic techniques they must rely on today to monitor Soviet nuclear tests, do not provide yield estimates with the accuracy required for effective verifications of compliance. The alternative seized upon was hydrodynamics. The US technique is called CORRTEX, a mercifully terse acronym for Continuous Reflectometry for Radius versus Time Experiments. A cable connected to a suitcase-sized electrical unit and a microcomputer is buried in a deep satellite hole roughly 50 feet away from the emplacement hole holding the nuclear device. The rate at which the CORRTEX cable is crushed and short-circuited by the shock wave generated by the exploding device provides the yield estimate. The paper compares the accuracy and constraints of both methods, and discusses the Soviet reaction to CORRTEX.
