Advanced Conductor Technologies
Boulder, CO
The Applied Superconductivity Center and the Magnet Science and Technology division of the Magnet Lab are collaborating with Advanced Conductor Technologies on the development and testing of Coated Conductor Stranded Cable (CCSC), using multi-layer spiraling tapes around a core, for magnet applications. Danko van der Laan, director of the company and associated with NIST/University of Colorado Boulder, is developing compact cables based on REBCO coated conductors, a high temperature superconductor. The ongoing collaboration resulted in the first measurements ever of HTS cables at low temperature and high magnetic field (4 K and 20 T in Cell 4).
Advanced Magnet Lab, Inc.
Palm Bay, FL
Engineers from the NHMFL are collaborating with Advanced Magnet Lab, Inc. to produce the innovative field-correction shims required to decrease spatial and temporal field disturbances in the Series-Connected Hybrid (SCH). Advanced Magnet Lab has provided the precision fabrication processes required to produce these innovative shims for the first-of-a-kind SCH magnet system that will produce 1 ppm field homogeneity at 36 T.

Helmholtz Zentrum Berlin
Berlin, Germany
The MagLab has partnered with the Helmholtz Zentrum Berlin (HZB) to develop the highest field magnet worldwide for neutron scattering at HZB. In March 2007, HZB (formerly the Hahn-Meitner Institute) signed an agreement with Florida State University Magnet Research and Development Inc. The magnet is intended to provide 25 T on-axis using 4.4 megawatts of DC power and have upstream and downstream scattering angles of 30 degrees. The present record field for such a configuration is 17 T. Five external design reviews have been held with an international committee of reviewers. Fabrication of the magnet is underway: The superconducting strand has been delivered and cabled and jacketed, the cryostat has been fabricated, winding of the superconducting coil is complete, joints have been fabricated, reaction of the coil to form the superconductor is complete, impregnation of the CICC coil is underway, design of the resistive insert coils is complete and fabrication of them is starting. In the summer of 2013 the cold-mass should ship to Italy where the cryostat will be assembled around it prior to transport to Berlin.

International Thermonuclear Experimental Reactor (ITER)
US-ITER Project Office, Oak Ridge National Laboratory (ORNL) Oak Ridge, TN
The United States is part of an exciting international collaboration to demonstrate the feasibility of an experimental fusion reactor that is under construction in France. The MS&T’s Mechanical Properties Lab is the US-ITER primary materials research and qualification laboratory supporting the US effort. The Tokamak machine consists of three types of very large complex superconducting magnets that all utilize Cable-in-Conduit Conductors as the main structural components. Another important component for stress management of the Central Solenoid is a massive CS pre-compression structure (Tie Plates). The conduit and tie plate alloys, and their welds are being studied and characterized here to ensure their performance and reliability. The funding for this research is provided by US-DOE, US-ITER Project Office at ORNL.
