According to the Primakoff effect, axions and axion-like particles can transform into photons in the presence of a strong magnetic field. To continue the search for these hypothetical particles, a new helioscope called the International Axions Observatory IAXO, and its subscale fully functional demonstrator BabyIAXO, are being designed.
To increase the sensitivity by a factor of a 100...
The new Nb3Sn superconducting magnet system for the fourth-generation 45 GHz ECR source is under developing in the institute of Modern Physics(IMP). A mirror structure of the Nb3Sn sextupole testing coil based on a key and bladder technology is used for studying the coil's mechanical, thermal and quench performance under the realistic conditions. This paper describes the main components and...
An Experimental Muon Sourse (EMuS) is proposed to construct at the facility of China Spallation Neutron Source (CSNS) by IHEP (Beijing, China), for the R&D of key technologies of the next-generation neutrino beam facility. The capture superconducting solenoid magnet is one of the key components of the EMuS. It consists of 4 coils which are an axially graded solenoids with a peak central field...
The energy upgrade of the Large Hadron Collider (HE-LHC) and the Future Circular Collider (FCC) demand new requirements that the magnetic field of accelerate magnets should be up to 16 T. The Nb3Sn Rutherford cable is used for magnet design. Due to the complex geometry and working conditions of the magnets, Rutherford cables have to suffer complex stress condition. To better understand the...
A multi-scale mechanical model of Rutherford type, low temperature superconducting cable is discussed in this paper.
The homogenization of the mechanical properties of the superconducting bundle is explained, at room and cryogenic temperature. The inclusion of a high definition three-dimensional sub-modelling of the strand geometry is illustrated, up to the superconducting filaments scale....
In the framework of the High-Luminosity Large Hadron Collider (HL-LHC) project, a complex assembly, known as the beam screen, will be installed by 2024 in the aperture of the new Nb3Sn HL-LHC triplet magnets (MQXF) nearby the ATLAS and CMS experiments. The beam screen is an octagonally shaped pipe that ensures that the vacuum conditions, required for the stability of the beam, are met. It...
The KSTAR central solenoid (CS) is a vertical stack of four pairs of coils compressed axially by preloading structures. The axial compression on the CS coils is monitored by measurements of strain and displacement, which are important monitoring parameters for safe operation of KSTAR. The equivalent vertical force methodology of a simplified multi-spring system was developed to analyze the...
