The project regards the design of the liquid helium transfer line for the Production Solenoid; this solenoid is a part of the magnets structure that is going to be used into the Mu2e project at Fermi National Accelerator Laboratory.

The first phase of the project involves the cross section layout and the support design with the purpose of limiting the heat load on the coldest pipe inside the line and at the same time reducing the support costs.

The second part considers the thermal contraction effects and describes the solutions adopted to reduce its effects on the structures.

Finally, it has been carried out a consumptive analysis that demonstrates the operated reduction in costs and the limited total heat load on some target parts in the line.
