899. Hybrid Microscopy to Clarify Failure Mechanisms of REBCO Tapes in Meter-Class Pancake-Coils (FRI-OR7-303-01)

Takanobu Kiss (Kyushu University)

Oral

It is required to improve yield of coiling for REBCO-based magnet developments, however, the conventional test method represented by the end-to-end current transport measurement of the coil could not derive detailed information such as the positions of the defects and the mechanisms for the failures. In this study, we have developed a novel method adopting hybrid microscopy integrating...

420. Integration of Bi-2212 and Nb3Sn CCT magnets for a hybrid magnet test (FRI-OR7-303-03)

Laura Garcia Fajardo (Lawrence Berkeley National Laboratory)

Oral

High temperature superconducting (HTS) magnets working as inserts inside low temperature superconducting (LTS) magnets are foreseen to enable >16 T class accelerator dipoles for future particle colliders. Under the U.S. Magnet Development Program (US-MDP), LBNL has been making steady progress towards designing and fabricating practical Bi-2212 and Nb3Sn canted-cosine-theta (CCT) dipoles that...

658. Development of a small-aperture cos-theta dipole insert coil based on Bi2212 Rutherford cable and stress management structure (FRI-OR7-303-04)

Oral

The U.S. Magnet Development Program (US-MDP) aims at developing high-field accelerator magnets with magnetic fields beyond the limits of Nb3Sn technology. Recent progress with composite wires and Rutherford cables based on high temperature superconductor Bi2Sr2CaCu2O8-x (Bi2212) allows considering them for this purpose. However, Bi2212 wires and cables are sensitive to transverse stresses and...

877. Experimental Study on Effectiveness of Different Reinforcement Layouts Applied to Recent Bi-2212 Test Coils (FRI-OR7-303-05)

Dr Youngjae Kim (National High Magnetic Field Laboratory)

Oral

Recent development of Bi-2212 insert coil technology at National High Magnetic Field Laboratory (NHMFL) has shown promising in-field performance, ~ 440 A/mm2 at 16.3 T peak field in 2019, thanks to the matured conductor technology and reliable heat treatment process. Now Bi-2212 coil technology is entering to a new stage to be considered as a competitive candidate for high field (above 20 T)...

163. Development of HTS conductor for the central solenoid of compact fusion reactor TRT (FRI-OR7-303-06)

Victor Sytnikov (R&D Center @ Federal Grid Company)

Oral

The article presents the results of the preliminary development of the HTS conductor based on the VS-type design for the central solenoid of the compact thermonuclear reactor TRT, which is under development in Russia. The operating current of the conductor have to be at least 60.0 kA in the field of 15 T at temperatures of 5-20 K. The compactness of the magnetic system requires the creation of...
