Public lecture: “The Secret Histories of Laser Fusion”

Thursday, October 16th, 2014

Sorry for the radio silence last week! A lot has been going on over here. More on all that pretty soon. Tomorrow morning I will be putting up a post on the death of David Greenglass.

I wanted to let people in the greater New York City metro area know about a public lecture I am giving on Wednesday, October 29, 2014, as part of the New York City History of Science Society Consortium, at Columbia University.

Wellerstein - Laser fusion talk

“Clean, Limitless, Classified: The Secret Histories of Laser Fusion”

Alex Wellerstein, Stevens Institute of Technology

The invention of the laser and its proliferation in scientific settings created a unique problem for the United States government starting in the 1960s. The Cold War regime of nuclear secrecy had required an absolute legal distinction between “peaceful” civilian technology and “dangerous” military technology: the former needing wide dissemination and development by the private sector, the latter being tightly regulated under penalty of imprisonment and death. But the emergent technology of laser fusion began to challenge and blur these Cold War categories. For its proponents, which included both international scientists and private entrepreneurs, laser fusion held out the hope of clean, limitless power generation during a time of increasing energy instability. But at its heart was a form of physics that was, for government censors, far too near to the methods used in the design of advanced thermonuclear weapons. This talk will use newly declassified files to tell the international history of laser fusion in the 1960s and 1970s as a case study for looking at the unusual classification problems of late Cold War nuclear technology. 

This is a very fun talk, one I’ve been working on (and workshopping on) for a few years now. It is based on interviews with some of the pioneers of laser fusion technology, and a whole lot of documents I got declassified by the Department of Energy relating to the declassification of laser fusion technology in the 1970s, the KMS Fusion affair, and international development of inertial confinement fusion. In a world where some new fusion hype seems to be bursting out (or petering out) on a weekly basis, this is a history with more relevance than ever, and has some moments in it that are sure to shock and delight. For those who are more interested in the weapons side of the nuclear picture, there’s a lot going on related to that in this as well, in describing the back-and-forth between the work of H-bomb designs and the work on “civilian” applications, and the complete mess that this put the Atomic Energy Commission in as they tried to figure out their classification policies and priorities. There’s a lot going on in this one.

All are welcome — there doesn’t seem to be a need to RSVP. I don’t know if it is being recorded. I don’t think it is being streamed.
