Abstract
A system and method for treating a cavity comprises arranging a niobium structure in a coating chamber, the coating chamber being arranged inside a furnace, coating the niobium structure with tin thereby forming an Nb3Sn layer on the niobium structure, and doping the Nb3Sn layer with nitrogen, thereby forming a nitrogen doped Nb3Sn layer on the niobium structure.
Claims8
A system for treating a workpiece, the system comprising:
- a furnace;
- a housing configured to house the furnace;
- a coating chamber configured inside the furnace, the coating chamber configured to house a workpiece;
- a vapor material provided in a first crucible, in the coating chamber;
- additional vapor material provided in a second crucible, in the coating chamber;
- a first separate heater configured inside the coating chamber in the furnace, for heating the vapor material in the first crucible;
- a second separate heater configured inside the coating chamber in the furnace, for heating the vapor material in the second crucible;
- a fitting formed on the furnace;
- an endplate formed in the housing;
- and
- an access door formed in the endplate, the access door further comprising:
- a neck formed in the access door, the neck further comprising an outer heat shield, an inner heat shield and at least one heat shield pin connecting the outer heat shield and the inner heat shield.
