Nuclear warheads have a couple of characteristics that are central to the experiment. The testing took place at the Gaerttner Linear Accelerator (LINAC) Facility on the campus of Rensselaer Polytechnic Institute, using a 15-meter long section of the facility’s neutron-beam line. The experiment builds on previous theoretical work, by Danagoulian and other members of his research group, who last year published two papers detailing computer simulations of the system. The authors are Danagoulian, who is an assistant professor of nuclear science and engineering at MIT, and graduate student Ezra Engel. The method uses neutron beams to establish certain facts about the warheads in question - and, crucially, uses an isotopic filter that physically encrypts the information in the measured data.Ī paper detailing the experiments, “A physically cryptographic warhead verification system using neutron induced nuclear resonances,” is being published today in Nature Communications. Now MIT researchers led by Danagoulian have successfully tested a new high-tech method that could help inspectors verify the destruction of nuclear weapons. “And that really means a verified dismantlement of the weapons themselves.” “There’s a real need to preempt these kinds of dangerous scenarios and go after these stockpiles,” says Areg Danagoulian, an MIT nuclear scientist. Stored nuclear warheads might not be deliverable in a war, but they could still be stolen, sold, or accidentally detonated, with disastrous consequences for human society. It’s a logical approach but not a perfect one. cut the wings off B-52 bombers and left them in the Arizona desert, where Russia could visually confirm the airplanes’ dismemberment. To comply with the START treaty, for example, the U.S. Instead, past U.S.-Russia arms reduction treaties have called for the destruction of the delivery systems for nuclear warheads, such as missiles and planes, but not the warheads themselves. When countries sign arms reduction pacts, they do not typically grant inspectors complete access to their nuclear technologies, for fear of giving away military secrets. How do weapons inspectors verify that a nuclear bomb has been dismantled? An unsettling answer is: They don’t, for the most part.
