BEYOND SPECS: Fabrication of the Jefferson Laboratory Cryogenic Control Reservoirs
February 27, 2013
Case Study
Meyer Tool completed manufacture of six Cryogenic Control Reservoirs (CCRs) for the Thomas Jefferson National Accelerator Facility (Jefferson Lab). Five of the CCRs will be installed in the new Super High Momentum Spectrometer (SHMS) planned for the Jefferson Lab’s Hall C and the sixth will be installed in Hall D. Both projects are part of the 12GeV upgrade to the CEBAF Accelerator. The CCRs are cryogenic distribution boxes designed by Jefferson Lab. They include internal reservoirs to provide a continuous supply of liquid helium and liquid nitrogen to superconducting magnets through periods of disruption in the external supply. The manufacturing measures developed and implemented by Meyer Tool met all Department of Energy requirements for pressure vessels (10CFR851 Appendix A Part 4), eliminated the possibility of brazing flux contamination and minimized or eliminated weld distortion on the multiple internal vessels. The CCRs successfully completed cold testing, vacuum testing and pressure testing at Meyer Tool prior to being shipped to the magnet vendor for installation.Reducing Project Risk through engineering and manufacturability planning coupled with expert fabrication, Meyer Tool provided the CCCRs to the 12GeV upgrade project at the Lowest Total Cost of Ownership.
