“…The quadrupole magnet is subjected to a large heat load and radiation loads because the magnet will be placed immediately after the target that produces various isotopes with a 400-kW 600-MeV proton beam or 200-MeV/amu ion beams. The HTS version is proposed as an option for the NbTi cable in conduit design developed at NSCL [20] to reduce the cryogenic operation cost by increasing the operation temperature to approximately 50 K instead of 4 K. In order to achieve high radiation tolerance, a 25-µm-thick stainless steel foil is placed between coil turns instead of organic films, such as a polyimide film, as a turn-to-turn insulator.…”

“…For normal conducting magnet mineral insulation, hollow conductors are utilized for high radiation usage. The technology may be adjusted for superconductors, and one example is the NbTi cable in conduits, which was developed at NSCL [20]. Although it can achieve fully inorganic construction, there are obvious disadvantages with respect to the compaction factor, that is, current density.…”

Superconducting magnets are widely used in accelerator science applications. Muon production solenoids are applications that have recently attracted considerable public attention, after the approval of muon-related physics projects such as coherent muon to electron transition or muon-to-electron-conversion experiments. Based on its characteristics, muon production solenoids tend to be subjected to high radiation exposure, which results in a high heat load being applied to the solenoid magnet, thus limiting the superconducting magnet operation, especially for low-temperature superconductors such as niobium titanium alloy. However, the use of high-temperature superconductors may extend the operation capabilities owing to their functionality at higher temperatures. This study reviews the characteristics of high temperature superconductor magnets in high-radiation environments and their potential for application to muon production solenoids.

“…They are in the target chase and see a very large radiation dose and, therefore, must be radiation hard. There are two options we have considered: MgO insulated magnets and HTS magnets following the BNL magnets designed for the Facility for Rare Isotope Beams (FRIB) [196]. The current baseline design for the capture quad section of the pion capture channel (see Section IV C 1) uses magnets with a 40 cm bore.…”

Magnets in the fragment separator region of the Facility for Rare Isotope Beams (FRIB) would be subjected to extremely high radiation and heat loads. Critical elements of FRIB are the dipole magnets which are used to select the desired isotopes. Since conventional NbTi and Nb 3 Sn superconductors must operate at 4.5 K, the removal of the large heat load generated in these magnets would be difficult. High temperature superconductors (HTS) have been shown to be radiation resistant and can operate in the 40 K temperature range where heat removal is an order of magnitude more efficient than at 4.5 K. The coils of this magnet must accommodate the large curvature from the 30° bend that the magnet will subtend. This paper will describe the magnetic and conceptual design for these magnets.
