TUPE23 | Glidcop Brazing in Sirius’ High Heat Load Front-End Components | 216 |
|
||
Sirius is a 4th generation synchrotron light source in project. 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 Oxygen Free Electrolytic Cu (OFEC) has been replaced by the Glidcop, on 4th generation synchrotron applications, due to its good thermal conductivity and preservation of mechanical properties after heating cycles.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. | ||

WEPE06 | High Heat Load Front Ends for Sirius | 324 |
|
||
Funding: Brazilian Ministry of Science, Technology, Innovation and Communication (MCTIC) Currently under construction on Brazilian Synchrotron Light Laboratory Campus, Campinas/SP, Sirius is a 3GeV, 4th Generation Synchrotron Light Source. In this paper we describe the Front End that has been designed to transmit the intense synchrotron radiation generated by the insertion devices that will generate the most critical thermal stress, with a peak power density of 55.7 kW/mrad² and a total power of 9.3kW at 500mA in the storage ring. The functions of the main components and their location in the layout are described. Computational fluid dynamics (CFD) and structural simulations, that have been carried out to verify the performance under the high heat loads generated by Sirius, are also detailed along with the limits of temperature and stress that have been employed in the design. |
