| Type of Item | NHa C400 Prototype |
| Final destination | France |
| Project | HADRON THERAPY PROJECT |
| Materials | AISI 304L stainless steel with magnetic permeability lower than 1.2 |
| Pressure (bar) | Helium leak rate < 10-9 mbar l/s. |
| Note | Construction and testing of the NHa C400 prototype of the first compact superconducting cyclotron equipment for hadron therapy. SIMIC manufactured the helium vessel and vacuum vessel with stringent requirements: • Helium vessel integrated by magnets, which is a pressure vessel and contains two superconducting coils cooled down at 4,2K with helium liquid • Vacuum vessel inside which the helium vessel will be assembled with the relative screens • Very tight machining tolerances, considering the large dimensions of the pieces with thin walls. |
