Sources Sought/Request for Information: Bechtel Nevada is seeking sources that can provide a Demountable Intense Neutron Source Tube for Febetron 706 pulser. These tubes resemble the standard x-ray tubes for the Model 706 with the exception of internal modifications as specified in a technical paper by Chang and Leeper "Intense 3 ns neutron source", Rev. Sci. Instrum. 51(6), Jun. 1980 pp 715-720. The modifications permit the tube to output a pulse of neutrons. These design modifications are: 1) outer envelope must fit into and mate with a standard Febetron 706 2) anode tip (6.4-mm diameter) must permit mounting of Contractor supplied replaceable CD2 (deuteron source) 3) stainless steel cathode (0.25-mm thick) with 1-cm diameter aperture is spaced 3 mm from CD2 4) demountable stainless steel target (12.5-mm diameter, 0.38-mm thick) to be coated with erbium tritide by Contractor is placed 18.0 mm from the aperture cathode 5) tube is equipped with standard Quick Flange as vacuum pump port 6) spare stainless steel anode tips and targets Request all interested parties to submit product brochures, capability statements or other descriptive literature, which provides sufficient detail to enable preliminary functional evaluation.
