The cryogenic transfer line for XFEL/AMTF is dedicated for transferring cryogenic cooling power from helium refrigerators to a cryogenic test facility by means of the constant flows of supercritical and cold gaseous helium. The external envelope of this cryoline contains 4 cold process lines and a common radiation shield, as well as the system of supports and thermal contraction compensators. The line was designed and manufactured by Wroclaw University of Technology and KrioSystem Ltd, respectively, within the scope of Polish in-kind contribution to the XFEL project. Besides the minimisation of heat loads to transferred helium the design phase included the numerical analysis of the stresses and deformations on both the process lines and external envelope for a number of operational and failure modes. The paper describes the design of the cryogenic transfer line as well as the main phases of the manufacturing and assembly of its linear and elbow modules.
