Open cell conducting foams for high synchrotron radiation accelerators

Abstract

The possible use of open-cell conductive foams in high synchrotron radiation particle accelerator beam liners is considered. Available materials and modeling tools are reviewed, potential pros and cons are discussed, and preliminary conclusions are drawn.

Cooling capacity of high porosity open-cell metal foams as passive cryogenic radiators

“…Such applications include radiant burners [40], volumetric solar energy receivers [41], gamma ray shielding [42] and proposed replacement of perforated beam screens in high synchrotron radiation accelerators [43]. Open literature still lacks comprehensive research in radiation heat transfer study of open-cell metal foams [44].…”

Influence of Film Coating Thickness on Secondary Electron Emission Characteristics of Non-Evaporable Getter Ti-Hf-V-Zr Coated Open-Cell Copper Foam Substrates

“…The characteristics of high strength [ 12 ], a large surface area [ 13 ], excellent thermal properties [ 14 ], radiation features [ 15 ], and energy absorption capability [ 16 ] make Open-cell Metal Foams (OCMFs) an attractive material to be applied for radiation shielding and beam liner design [ 17 , 18 ] in particle accelerators. It is known that the geometrical modifications on a material surface can effectively suppress SEE from it [ 19 , 20 , 21 , 22 ].…”

“…Moreover, some characteristics of foamed porous coppers for beam screen were demonstrated as well, such as excellent vacuum behavior, low surface resistance, good mechanical structural properties, etc. [ 17 , 24 ]. These benefits suggested some potential use of the foamed porous coppers as an EC moderator in the accelerator technology.…”
