The beam separation dipole, MBXF, is being prepared by the High Energy Accelerator Research Organization, KEK, for the high luminosity LHC (HL-LHC) upgrade. The new magnet is designed to generate a central field of 5.6 T at the nominal operating conditions of 12.05 kA and 1.9 K. From the past design study, the magnet is designed as a single layer coil wound with a 15 mm wide NbTi/Cu Rutherford...
The Large Hadron Collider (LHC) upgrade, called High Luminosity LHC (HL-LHC) is planned for the next decade. A set of twin aperture beam orbit correctors positioned on the approaches to the ATLAS & CMS experiments will be development. The orbit corrector based on Canted Cosine Theta (CCT) design to achieve 5 Tm field integral and multipoles lower than 10 units in the twin aperture. Tow...
The new D2 recombination superconducting dipole is a key two-in-one NbTi magnet with a 105 mm bore aperture for the LHC high luminosity upgrade project (HL-LHC) expected in operation from 2024. A short model magnet of 1.6 m magnetic length has been designed by INFN (Genova), built by Ansaldo Superconductors Group, and cold tested at CERN within a INFN-CERN collaboration framework. This model...
The LHC beam separation dipoles plans to be replaced for the high luminosity LHC (HL-LHC) upgrade. The new separation dipole, MBXF, is based on the Nb-Ti superconductor, and is designed to generate 35 Tm at the nominal operating conditions of 12.05 kA and 1.9 K. The magnet has a stored energy of 0.34 MJ/m, and all the energy needs to be extracted only by quench protection heaters before the...
In the Large Hadron Collider (LHC) at CERN, it is expected that 35 out of the 122 MCBC and MCBY orbit corrector dipoles will receive up to 20 MGy of gamma radiation over the High-Luminosity (HL)-LHC lifetime. Since these magnets were not designed to withstand such high gamma doses, new MCBC and MCBY magnets have to be designed and produced using radiation hard impregnation insulation and...
The LASA Laboratory (INFN, Milan) is working in the High Luminosity LHC program for developing, in collaboration with CERN, 6 different types of High Order corrector magnets. In this framework, in parallel with a conventional design of superferric magnets with LTS conductor, the LASA Lab. is focusing on the research of novel superconducting materials which may have application in particle...
This paper presents an analytical method that fines the mutual influence of the magnetic field in a dipole magnet. A vacuum beam tube is in thermal contact with a cryogenic cooling pipe for a high-quality vacuum. These two different geometric components have different eddy current profiles. And the corresponding magnetic fields disturb the operation field quality. The cooling pipe in an...
Based on the collaboration of Institute of Plasma Physics Chinese Academy of Sciences (ASIPP) and Russia Joint Institute for Nuclear Research (JINR) for proton therapy, a 200 MeV compact superconducting proton cyclotron project (SC200 project) has been launched at ASIPP since 2016. The superconducting magnet is the most critical and challenging subsystem for the cyclotron to provide ~3 T...
Accelerator Driven System (ADS) is recognized as one of the most efficient ways to transmute minor-actinides. China initiative Accelerator Driven System (CiADS) project as ADS demonstration with 500 MeV has been approved in 2015. Three type superconducting focusing solenoids are used to focus and correct beam in CiADS superconducting LINAC. The focusing solenoid includes a solenoid coil and a...
