      A new article by me and @sovietologist (Ed Geist) on the history of the Soviet hydrogen bomb, out in @PhysicsToday:http://physicstoday.scitation.org/doi/10.1063/PT.3.3524#.WOS2INIJ92w.twitter …

      Basic thesis is that their "Sloika" design was less dumb, and less a "step in the wrong direction" than American commentators tend to think.

      So they went directly to a spherical secondary?It would be interesting to know if the US route with cylinderical sec is the exception 1/2

      Right. (We had some on this in an earlier draft but it was too long.) UK was a more Soviet-like route than a US-like route, in this model.

      Do we have any info on why US went with a cylindrical secondary? IIRC the use of a spherical one was considered a successive "breakthrough"

      They loved idea of infinite cylinder of fuel, unlimited bomb yield, from heating alone. Different than a compression-based approach.

      That was my guess too, but reading this interview with Carson Mark it seems that it was a deliberate choice, for the first TN at least.pic.twitter.com/PVferylzv4
