Table 2 List of type, length, inner diameter (regarded as hydraulic diameter) and heat-load specification for each cryogenic piping element of the LHe supply line. Note that the vacuum-jacketed solid line of L1 includes two vertical bayonets; the multi-channel line of L1 includes one cryogenic value

From: Pressure drop of two-phase helium along long cryogenic flexible transfer lines to support a superconducting RF operation at its cryogenic test stand
