Poster

In the framework of the U.S. Magnet Development Program, LBNL is planning to fabricate a high field hybrid magnet combining Nb3Sn and Bi-2212 dipole magnets. The Nb3Sn outsert will be a four-coil canted cosine theta (CCT) dipole magnet, designed to generate 14 T in a 120 mm bore diameter. The Bi-2212 insert aims to achieve the highest field possible in a 40-45 mm diameter bore. Coil designs...

Poster

This study presents the conduction-cooled current injection design/thermal gradient and cyclic testing for a ReBCO canted cos-theta magnet designed and Fabricated by LBNL (magnet C2). This coil has been measured at 77 K (LN2) and 4.2 K (liquid helium), as previously reported by LBNL, but in this case, we used a large conduction cooled cryostat available at OSU. Testing this coil in a...

Poster

Energy consumption represents an increasing critical challenge for particle physics research laboratories like CERN. This issue is particularly significant in large accelerator facilities, where normal conducting magnet technology plays a fundamental role in the beamline design. In this context, research, development, and study of high-temperature superconducting (HTS) magnets offer promising...

362. Sat-Mo-Po.07-05: Thermal properties of Block-type dipole superconducting magnets wound using REBCO cables with defects and specified thermal and electrical interface properties

Poster

Quench and protection in superconducting magnets wound using REBCO cables is important for high energy particle accelerators. Quite large minimum quench energy (MQE) and quite low normal zone propagation (NZP) velocity has led to an interest in electrically non-insulation coils. We analyzed numerically, using a Finite Element Method (FEM), the performance of REBCO cable containing various...

74. Sat-Mo-Po.07-06: Double Aperture HTS Dipole Magnet Model for the Persistent Current Operation

Daniele Turrioni, Vladimir Kashikhin

Poster

Magnet systems of particle accelerators consist of many various types of magnets. There is an interest in replacing rather low-field conventional resistive magnets with high-temperature superconducting (HTS) magnets. The main goal is to reduce operational expenses which is critical during the continuously increasing cost of electricity. At Fermilab were built and successfully tested several...

101. Sat-Mo-Po.07-07: Study of Shielding Current Characteristics in High-Temperature Superconducting Dipole Magnets

Prof. Wenjie Yang (Institute of modern physics)

05/07/2025, 09:30

Poster

High-temperature superconducting (HTS) magnets, with their superior current-carrying capacity and high operating temperatures, have shown considerable potential for applications in medical imaging, particle accelerators, power transmission, and scientific instrumentation. However, HTS coated conductors (CCS) are susceptible to significant shielding current effects due to their high aspect...

630. Sat-Mo-Po.07-08: Design and prototyping of CORC CCT inserts for testing in background dipole fields

Yufan Yan (Lawrence Berkeley National Laboratory)

Poster

We present design options and initial prototyping of CORC Canted Cosine Theta (CCT) dipole inserts compatible with testing in the ~8 T background field of the existing Nb3Sn outsert CCT5. We explore different CCT geometries and configurations, seeking to optimize the coil geometry to meet the minimum bending radii requirements of the CORC conductor with maximum coil magnetic efficiency. The...
