Vacuum system for the Livermore intense neutron source

PDF Version Also Available for Download.

Description

To fulfill the need for intense 14-MeV neutron sources for controlled thermonuclear reactor material damage studies, several accelerators will be built at the Lawrence Livermore Laboratory. A high-capacity vacuum system will be required to handle the large deuterium gas load needed to produce the beam current. Outgassing of tritium from the target necessitates special handling of the exhaust from the vacuum pumps. A vacuum system utilizing turbomolecular pumps was selected after comparing its performance with mercury vapor diffusion and titanium bulk sublimation/ion pumps. (auth)
