After we have developed the 25 T cryogen-free superconducting magnet (25 T-CSM) with a Bi2223 insert, Nb3Sn and NbTi Rutherford outsert coils [1], we are planning two projects on high field cryogen-free superconducting magnets. One is an upgrade of the 25T-CSM to 30 T with replacing the present Bi2223 insert to an REBCO one [2]. The other plan is to build a new high field CSM beyond 30 T. For...
The National High Magnetic Field Laboratory (NHMFL) has launched an innovative project to develop a 40 T all-superconducting user magnet. The first year of funding was awarded by the National Science Foundation and the project started in September 2018. Consideration of a 40 T superconducting user magnet set target specifications of a cold bore of 34 mm with a homogeneity of 500 ppm over a 1...
After a successful first test of the 32 T superconducting magnet, it was inspected and prepared for commissioning. Here we report on the initial result of reaching 32 T, meeting the specifications and other pertinent observations from the first test. Following is a brief description of the facilities at its permanent location as a user magnet in the expanded NHMFL MilliKelvin building. The...
Following the development of wide bore superconducting magnets using low temperature superconductors (LTS) for integrating ultra-high field high temperature superconductor (HTS) inserts, new applications for this LTS ‘outsert’ technology require higher temporal and mechanical stability. The development of an 18 Tesla, 150mm bore magnet system designed for scanning tunneling microscopy (STM)...
The High Field Magnet Laboratory of Radboud University is constructing a 45 T hybrid magnet system. The 620 mm bore, 12.3 T, 20 kA, Nb3Sn cable-in-conduit superconducting outsert magnet has been developed and fabricated in close cooperation with the National High Magnetic Field Laboratory in Tallahassee FL. A 22 MW/40 kA resistive insert magnet will contribute another 32.7 T to the total...
The Grenoble Hybrid magnet is a modular platform applying resistive and superconducting technologies to deliver various continuous high magnetic field and flux configurations. They range from 43 T in 34 mm diameter with 24 MW down to 9 T in 800 mm with the superconducting coil alone. The key design parameters are recalled including the specifically developed conductor, the large bore...
Brookhaven National Lab (BNL) is in the process of building a 25 Tesla, 100 mm cold bore HTS solenoid for the Institute of Basic Science (IBS) in South Korea for their search for Dark Matter Axions. The magnet consists of 28 coils (in a 14 double-pancake (DP) coils configuration) with an inner diameter of 105 mm and has an outer diameter of 200 mm, wound using Second Generation (2G) High...
