The Grenoble Hybrid magnet is a modular platform using resistive and superconducting technologies to produce various DC high magnetic field and flux configurations for the scientific community. They range from 43 T in 34 mm diameter with 24 MW of electrical power to 9 T in 800 mm diameter, when the superconducting coil is used alone. Thanks to the ongoing upgrade of the electrical power...
To extend its user’s facilities the High Field Magnet Laboratory (HFML) of the Radboud University is in the process of building a 45 T hybrid magnet. The magnet system will consist of a 22 MW, 32.7 T Florida-Bitter type of resistive insert and a 600 mm bore, 12.3 T Nb3Sn based CICC type of superconducting outsert magnet. The Nijmegen hybrid magnet will be operated with separate current sources...
In the quest for all-superconducting very high field magnets, the first successes where obtained with High Temperature Superconducting inserts wound using BiSrCaCuO conductors. It is the case for the 25T CSM (Cryogen-free Superconducting Magnet) installed in 2015 at the HFLSM (High Field Lab. for Superconducting Materials). It remains to date the only magnet above 24T that is fully open to...
A large-bore Nb3Sn “cable test facility magnet” designed to test advanced cables and inserts in a high transverse background field, is here proposed. The project is funded by the U.S. Department of Energy (DOE) Office of Science (SC). The test facility dipole magnet (TFD) creating the background field is developed at the Lawrence Berkeley National Laboratory (LBNL). In line with the...
A 35 T/17 mm cold-bore full superconducting magnet has been designed. It consists of a 15 T LTS background magnet with the inner radius of 150 mm, and a 20 T HTS insert magnet with the inner radius of 17 mm. We hybrid used no-insulated and steel-insulated REBCO tapes to wind the HTS insert, with the aim of protecting part of HTS coils in a relatively safe state. Two mechanical models were...
A 25 T All YBCO superconducting magnet with a warm bore of 52mm is designed for high-frequency gyrotrons in Wuhan National High Magnetic Field Center (WHMFC). The designed peak-peak field inhomogeneity is 50 ppm within 10mm Diameter of Spherical Volume (DSV). The magnet includes Inner, middle and Outer Coils which consists of 34, 56 and 68 double pancakes (DP) wound by bare YBCO tape,...
In 2015, we achieved 24.6 T by the 25T cryogen-free superconducting magnet (CSM) with a Bi2223 insert. Then it has been used as a user magnet at High Field Laboratory for Superconducting Materials, IMR, Tohoku University. The Bi2223 insert consists of 38 double pancake coils with high strength Ni-alloy/ Bi2223 tapes (Sumitomo type HT-Nx) [1]. In this case, we used turn separation in the middle...
