CRYOGENIC SYSTEM FOR COOLING SUPERCONDUCTING CYLINDRICAL COILS

The invention relates to a cryogenic system for cooling superconducting coils, meant to be used in the field of particle accelerators. According to the invention, the system consists of a cryocooler (1) having a first cooling end operating at a temperature of 50K, with the role of cooling a thermal screen (3) with a view to reducing thermal radiation of a cryostat (2), and a second cooling end operating at a temperature of 4K, with the role of cooling a condensation enclosure (4) and some condensation elements (5), with the view to condensing gaseous helium from the cooling of superconducting coils (11) into liquid helium, passing through a spiral cooler (9) and some gaseous helium access tubes (7) and liquid helium drain tubes (6) and a central channel (12) which is meant to allow the access of accelerated particles into the generated magnetic field zone, in order to correct the size and shape of particle flow, by the action of the magnetic field generated by the superconducting coils (11).
