title = "A cryogenic tritium target system for nuclear physics experiments",
abstract = "A cryogenic tritium (3H2) gas target system was constructed and used for a program of electron scattering studies. The 3H2 was supplied and safely stored as solid U3H3. For the experiments, it was transferred to a thin walled cylindrical cell, where it was exposed to 25 μA electron beams with energies up to 800 MeV. During operation, the target cell contained 115000 Ci of tritium at 225 psia and 45 K. Multiple safety enclosures surrounded both target and gas transfer systems. A microprocessor-based control and monitoring system presented target parameters to the operators, identifying those out of range. The target system operated safely and effectively for about 2000 h, enabling completion of comprehensive elastic and elastic electron scattering study of the three nucleon system.",

note = "Funding Information: The collaboration wishes to express its gratitude to Dick Maltrud and his colleagues at Group W.X-5 at Los Alamos, both for the loan of the tritium and for the many valuable suggestions that they offered. In addition we wish to thank the Radiation Protection and Safety Offices at Bates for their assistance - in particular, Gerry Fallon, Dick Keating, Dennis Boyden and John Quattrochi. The technical staff at Bates, including Don Biron and Bob Terenzoni, also deserves great credit for the success of the project. Finally, the administration and users of Bates are to be commended for their help and patience during the construction and operation of the target system.
