The Advanced Photon Source Upgrade includes four 4.8-m long superconducting undulator (SCU) cryostats, each containing two up to 1.9-m long planar undulator NbTi magnets. The cooling is provided by six cryocoolers arranged in three thermal circuits. The magnets are indirectly cooled with LHe penetrating through channels in the magnet cores. This 4-K circuit which also includes a LHe tank, is...
The Advanced Photon Source (APS) is in the midst of a major facility upgrade consisting of a new electron storage ring (SR) and many new insertion devices (IDs) which will provide x-ray photon beams to a new suite of experimental end stations. Included among the new IDs are four 4.8-meter superconducting undulator (SCU) cryostats, each containing two 1.9-meter planar undulator magnets...
A superconducting multi-coil magnet system has been designed, analyzed and optimized, serving as demonstrator for a high filed Magnetic Resonance Imaging (MRI). This work focuses on the design and optimization of superconducting magnet, cryogenic cooling and cryostat systems.
The NbTi magnet system with multi-coils design has been optimized by balancing magnet performance, stability and...
The 1 MW HTS induction heater has developed for the non-ferrous metal industry where the HTS coil is used to generate a static magnetic field. The HTS magnet is made of YBCO conductor produced by Shanghai Superconductor, and the prospected operating temperature is about 25 K. The conduction-cooled HTS magnet consists of three solenoid coils wound with 18 km YBCO conductor. The inner and outer...
At present,Ultra-high field MRI system is considered the right way to explore the human brain because of the brain activity would be seen at a resolution of hundreds of micrometers. In 2017,the Chinese government launched an ambitious project to design and manufacture a 14T MRI system in object to neuroscience research in future.The superconducting magnets made of Nb3Sn superconductor and NbTi...
Studies suggest that an insulated ReBCO tape solenoid coil that is well-coupled inductively to shorted secondary can effectively be quench protected by discharging the coil across a constant voltage resistor. The discharge voltage across the constant voltage resistor is much lower than it would be for a constant resistance resistor that is used to achieve the same final quench temperature...
The HL-LHC Project currently undertaken by CERN that provides an upgrade to the existing LHC accelerator, is designed to increase the luminosity of the colliding particle bunches by a factor of at least five.
Part of this upgrade will require the replacement of the existing groups of three superconducting LHC triplet magnets situated on each side of the ATLAS and CMS detectors with similar...
In the frame of the HL-LHC project, innovative technical solutions are sought to measure accurately the position of the magnet cold mass inside the cryostat. To this end, a system based on laser-interferometry is being designed to monitor the displacement of the cold mass through dedicated openings in the new HL-LHC cryostats.
In order to test such a system on a full-scale setup in...
