Design considerations for MgB2 ADR superconducting coils.

Author(s) : HOPKINS S. C., MORAWSKI A., GLOWACKI B. A., et al.

Summary

The adiabatic demagnetisation refrigerator (ADR) is the preferred technology for cooling cryogenic detectors for space applications. MgB2 has excellent potential for these applications, and an ADR with MgB2 magnet coils is in development to meet the requirements of the European Space Agency's XEUS project. These include the production of 3 T at 15-20 K with current not exceeding 15 A, placing considerable demands on MgB2 powder-in-tube conductor technology. Practical options for wire design, matrix material, starting powders, dopants and thermomechanical processing are quantitatively reviewed, and experimental results presented, to support design proposals for these conductors.
