Laser-induced surface roughening is a technique that facilitates the reduction of secondary electron emission (SEE) from materials, which crucial for mitigating cloud (EC) formation in particle accelerators, that...
The presence of strong electron clouds in the quadrupole magnetic field regions Large Hadron Collider (LHC) leads to considerable heating that poses challenges for cryogenic cooling system, and under certain conditions proton beam quality deterioration. Research is being conducted on laser-treated inner screen surfaces upgraded High-Luminosity LHC mitigate this issue. Laser-induced surface structuring, a technique effectively roughens surfaces, has been shown reduce secondary emission; an...
In the framework of Future Circular Collider Study a new septum magnet concept ("SuShi") has been developed, and prototype was built at Wigner RCP, tested FREIA facility Uppsala University. The uses canted cosine theta (CCT)-like superconducting passive shield to create zero-field high-field region within its aperture. SuShi is first CCT with both winding layers simultaneously impregnated wax. Details construction will be presented, special emphasis on wax impregnation procedure which deals...
A zero-field cooled superconducting shield was previously proposed to realize a high-field (at least 3 T) septum magnet for the Future Circular Collider proton-proton ring. In this paper, we present conceptual design of complete prototype including with an optimized shape and simple cost-effective using canted cosine theta concept. 2D optimization coil geometry realistic simulation fieldmap field homogeneity are presented taking into account nonlinear penetration magnetic shield.
The use of bulk MgB <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> as a magnetic shield may have interesting applications in the accelerator field protection particle beams. Many these will require low-temperature environment due to high fields involved; therefore, stability superconducting materials, at low temperatures, must be carefully controlled. Critical issues materials include macro- and micro-flux jumps, which are related,...

Abstract In the framework of Future Circular Collider Study a new septum magnet concept, nicknamed ‘SuShi’ has been developed, and prototype was built at Wigner Research Center for Physics, tested FREIA facility Uppsala University in April 2023. The concept uses canted cosine theta (CCT)-like superconducting passive shield to create zero-field high-field region within its aperture. SuShi is first CCT with both winding layers simultaneously impregnated wax. This paper describes powering test...
The shielded pair resonator method is a useful tool in the measurement of accelerator components, such as beam screens used Large Hadron Collider (LHC), High-Luminosity (HL) LHC, or future accelerators. It can measure resistive losses at several frequency points by separating on sample from other sources losses. We built new to be inserted into superconducting dipole magnet (peak magnetic field 9.5 T) and surface resistance screens, LHC coated with amorphous carbon (a-C). device any...
