Abstract :
High-vacuum beam transport tubes are being designed for use in an accelerator under development at Los Alamos. In areas such as weld-heat-affected zones, the tubes will require localized magnetic permeability of less than 1.02. Seven austenitic stainless steel candidates, 304L, 310, 316L, 317LN, 20Cb-3, Nitronic 33, and Nitronic 40 have been evaluated to determine their permeability in cold-worked, annealed, and weld-affected zones. Candidates 30 and 20Cb-3 showed permeability after welding of less than 1.01.<>
