Some of Sirius’ beamlines will have a very high power density, more than 50 kW/mrad², to be dissipated in components that have a limited space condition. Thus, the refrigeration of these components is complex when one has in mind that the coolant flow cannot be too turbulent in order to not induce much vibration in the components. Oxygen Free Electrolytic Cu (OFEC) has been replaced by the Glidcop, on 4th generation synchrotron applications, due to its good thermal conductivity and preservation of mechanical properties after heating cycles. However, as this material is not very workable in terms of union with other materials, which led to the development of a brazing process for Glidcop and stainless steel union. Glidcop samples were submitted to a Cu-electroplating process and a silver base alloy (BVAg-8) was used to join the parts in a high vacuum furnace. Electroplating was used to improve the filler metal wettability. The results were very satisfactory, ensuring water and vacuum tightness. A desirable characteristic not yet proved is the virtual leak property. This paper will discourse about this brazing method.
