COMET experiment is aiming to search for a muon to electron transition at J-PARC. It requires the muon beam with high intensity of 10$^{11}$µ$^−$/s. The muon beam is produced by using a series of superconducting solenoids. The solenoid magnet in which the production target is embedded, called as COMET pion capture solenoid, is estimated to be exposed to severe radiation such as the neutrons of...

The third generation of electron cyclotron resonance (ECR) ion sources is in operation or under development in the world. The fourth generation ECR ion sources are expected to operate at a heating radio frequency greater than 40 GHz, requiring a higher confinement field. Such requirements provide the motivation to design the structure of the fourth generation ECR ion sources. The Nb3Sn wire,...

Muon ionization cooling is theoretically well understood but has never been fully demonstrated experimentally. Ionization cooling is regarded as an important technology both in terms of cost and performance for a Neutrino Factory and is absolutely essential for a Muon Collider. The MICE experiment (Muon Ionization Cooling Experiment), based at the Rutherford Appleton Laboratory in the UK, is...

The production of superconducting magnets involves tight tolerances and high precision assemblies, in order to achieve the requirements for their appropriate performance. It is therefore essential to have a strict control and traceability over the geometry of each part of the system, and also to be able to compensate possible inherent deviations coming from the production process. The...

High-temperature superconductors (HTS) have a much larger thermal margin than low-temperature superconductors (LTS) due to high critical temperature and high upper critical field. It allows HTS magnets to operate stably so as to tolerate very high heat loads due to radiation. Therefore research on development of HTS quadruple magnet is progressed widely. The Quadruple magnets are used for...

In the design of superconducting accelerator magnets the outline of the coil cross-section is in large part attributed by the minimization of the conductor volume, constrained by the central magnetic field and homogeneity. Such optimizations commonly assume either a Block or Cosine Theta coil type, which is then filled with (pre-determined) rectangular or key-stoned Rutherford cables. By...

In many applications dipole magnets with coils having significant curvature are needed. This is particularly challenging for high temperature superconductors (HTS) as they are brittle. One application for curved HTS coils is the fragment separator dipole magnets for the Facility for Rare Isotope Beams (FRIB). These magnets operate in a high radiation environment and are subject to a high...

Magnets wound with coated conductors are attractive for the applications to accelerator systems because of high magnetic field generation and easy cooling by using cryocooler. In accelerator systems, the time-dependent and precise magnetic fields are sometimes required. However, large magnetization in wide coated conductors deteriorates field qualities of magnets, and the temporal behavior of...

The superconducting dipole magnets of the Large Hadron Collider operate in a superfluid helium bath at 1.9K. As a part of the magnet quench protection system, each dipole magnet is equipped with a by-pass diode located in the helium bath. The connection between the superconducting magnet and the cold by-pass diode is made through a clamping system called “half-moon”, located at the lowest...

A novel scheme of the superconducting dipole magnet which superposes two concentric and oppositely titled solenoids with respect to the bore axis is described. A designed dipole magnet prototype consists of four tilted solenoids by using a 7-strands NbTi superconducting cable and will produce a 2 T magnetic field with operating current of 3 kA. The bore diameter is 50 mm. The detailed magnetic...

A proton accelerator requires a wide range of beam properties such as beam energy, beam current, beam repetition rate, and beam pulse width. The electron beam ion source (EBIS), which can perform short pulse operation up to 1 μs, can meet the diverse requirements of users by facilitating enhanced utilization efficiency and broad application area. Therefore, the purpose of this study is to...

The new FNAL g-2 experiment is based on the muon storage ring previously used at BNL. The 1.45 T dipole magnetic field in the storage ring is required to have very high (1 ppm) homogeneity. The muon beam injected into the ring must be transported through the magnet yoke and the main superconducting coil cryostat with minimal distortions. The old inflector magnet shielded the main dipole fringe...

The EMuS is an excellent platform for the R&D of the key technologies of the next-generation neutrino beam facility at CSNS (China Spallation Neutron Source), also for the multi-disciplinary applications based on μSR technique. The dipole on the EMuS beamline used for minus/positive particle selection and deflection is designed as a superferric magnet in detail because of its large aperture...

The LASA Lab. (INFN, Milan) is developing a a new type of superferric magnets suitable to arbitrary multipole order which we refer to as Round Coil Superferric Magnets (RCSM). It is based by the previous proposal of I. F. Malyshev and V. Kashikhin. This type of magnets is suitable for strain-sensitive superconductors, because it only uses a single round coil, which has a large bending radius,...
