Helium circulation loops developed by Absolut System are used in numerous innovative scientific applications such as HTS magnets (Cyclotron, Tokamak..), HTS cables, HTS motors, HTS Fault Current Limiters, Thermal shields, cold traps, mechanical test benches and cryopumps.
The paper presents a 600W @ 20K remote Helium Cooling Loop developed and optimlized for the cooling down of demonstration SPARC magnets.
The design, production, Factory Acceptance Tests and installation will be described.
