Antimatter weapons (1946-1986): From Fermi and Teller's speculations to the first open scientific publications

Abstract

We recall the early theoretical speculations on the possible explosive uses of antimatter, from 1946 to the first production of antiprotons, at Berkeley in 1955, and until the first capture of cold antiprotons, at CERN on July 17-18, 1986, as well as the circumstances of the first presentation at a scientific conference of the correct physical processes leading to the ignition of a large scale thermonuclear explosion using less than a few micrograms of antimatter as trigger, at Madrid on June 30th - July 4th, 1986.
