	Meyer Tool and Manufacturing of Oak Lawn IL is manufacturing six Cryogenic Control reservoirs CCRs) for the Jefferson Laboratory. Five of the CCRs will be installed in the new Super High Momentum Spectrometer (SHMS) planned for Jefferson Lab's Hall C and the sixth will be installed in Hall D. Both projects are part of the 12 GeV upgrade to the CEBAF accelerator . The CCRs are a cryogenic distribution box designed by the Jefferson Laboratory. They include internal reservoirs in order to provide a continuous supply liquid helium and liquid nitrogen to magnets through periods of disruption in the external supply. This paper discusses the manufacturing and process measures that were implemented in order to meet the Department of Energy requirements for pressure vessels (10CFR851 Appendix A Part 4), to eliminate brazing flux contamination, and to reduce weld distortion in multiple internal vessels. The CCRs will undergo pressure and vacuum testing at Meyer Tool before being installed by the magnet manufacturer.
