Possibility of target fabrication from beryllium deuteride (foaming technique)

We have developed a new method of fabrication of spherical shell laser targets of beryllium deuteride. The targets possess sufficient strength and long lifetime in deuterium- tritium mixture. The method is based on the original technology of producing the BeD2 and BeDT layers developed at Bochvar Institute, and a high-temperature technique of shell formation from fast decomposed matters developed at Lebedev Physical Institute. The performed investigation has shown that beryllium deuteride possesses all the properties necessary for a spherical target: the hydrogen isotopes permeability comparable to the permeability of a quartz glass, and the tensile strength higher than that of polymers.
