Germany – Gas-distribution network – Feedbox 10 and 50 for SIS100

The SIS100 Feed Box system is part of local cryogenics system for the SIS100 synchrotron at FAIR. The Feed Box system distributes the cooling power to the SIS100 magnets and Current Lead Boxes by flow of cold helium in different thermodynamic states, including liquid, vapor, supercritical and cold gas for thermal shielding of the low temperature circuits, including a phase separator with a sub-cooler (PED, cat 4) and ca. 30 cold valves (DN6- DN100).
