HEL pre-design
Diego Perini 31.10.2014
Superconducting solenoid• Operation temperature: 4.2 K, current:about 250A, magnetic field: 5 Tesla • Cooled by liquid helium• Three vessels: for liquid helium, thermal screen and vacuum• The helium vessel is supported by the permaglass bars in vertical and
horizontal directions and in axial direction with plastic piece• The main coils and the correction coils are inside the helium vessel
