Summary:

The Continuous Electron Beam Accelerator Facility (CEBAF) has three refrigeration systems which supply many users with liquid and gaseous helium and liquid nitrogen at different state points. Static vacuum transfer lines of varying sizes and geometries transport the cryogens. The simplest has 2 flow paths and the most complex has 5 flow paths including a 4.5 K subcooler. CEBAF will have nearly 2 km of transfer line varying in size from 11.4 cm to 40.6 cm outside diameter. The transfer lines have eccentric flow shield circuits which convey LN(sub)2 or 40 K to 50 K helium gas to intercept the main 300 K heat leak. All of the transfer lines have been designed and fabricated at CEBAF.
