Nb3Al has advantages of better tolerance to strain/stress and a higher critical magnetic field
(30T at 4.2 K) for stoichiometric composition over Nb3Sn. The rapid-heating, quenching and …

Jelly-roll (JR) processed wires using metal thin foils as starting materials have excellent cold
workability and drawability. We have successfully fabricated Nb/Al composite mono-core …

Characteristics of developed Nb 3 Al strand though the RHQT (rapid heating/quenching and
transformation) process are described. One kilometer-long copper stabilized Nb 3 Al round …

To suppress the low-magnetic-field instability (flux jumps in low magnetic fields) of a rapid-
heating, quenching and transformation (RHQT) processed Nb 3 Al superconductor, we had …

Feasibility study of Cu stabilized Nb 3 Al strand and Rutherford cable for the application to
high field accelerator magnets are being done at Fermilab in collaboration with NIMS. The …

To enhance the non-Cu critical current density J c at 15 T and 4.2 K (1000 A mm− 2 at
present) we have endeavoured to refine the grain size of rapid heating, quenching and …

Two Cu stabilized Nb 3 Al strands, Fl (Nb matrix) and F3 (Ta matrix), fabricated at NIMS were
wound into Rutherford cables at Fermilab in collaboration with NIMS. A small race-track …

Research and development of Nb 3 Al strands and cables for a high field accelerator
magnet is ongoing under the framework of the CERN-KEK collaboration. In this program …

Research and development of copper stabilized Nb 3 Al strands and cables for a high field
Nb 3 Al common coil magnet is ongoing with the cooperation of KEK-NIMS-Fermilab. In this …

In this experiment, we designed, constructed and tested a 21 T superconducting magnet to
be operated at 4.2 K, consisting of a Nb 3 Al inner coil with an exclusive power supply, and a …
