METHOD FOR INCREASING THE Q-FACTOR AND THE MAXIMUM ACCELERATING FIELD IN SUPERCONDUCTING CAVITIES, SUPERCONDUCTING CAVITY MADE ACCORDING TO SUCH METHOD AND SYSTEM FOR PARTICLE ACCELERATION USING SAID CAVITY

摘要

The subject of this invention is a method for manufacturing a superconducting cavity (1,1') for particle accelerators comprising said cavity (1,1') comprising at least one shell wall (3) adapted to define an internal hollow volume (21), said shell wall comprising an inner surface (31) made of Niobium and an outer surface (32) facing towards a cooling fluid, preferably Helium in the liquid phase, wherein on the outer surface (32) a coating is provided, preferably of micrometric thickness, intended to adapt the thermal impedance between said cavity (1,1') and said cooling fluid, said coating being made from material having a Debye temperature that is lower than that of the material from which the outer surface (32) is made, other objects of the invention include a superconducting cavity thus formed, and a system for the acceleration of particles comprising such a cavity.
