Assembly, Commissioning and Operation of the NHMFL 100 Tesla Multi-Pulse Magnet System

The U.S. National High Magnetic Field Laboratory 100 Tesla multi-pulse magnet system is now successfully commissioned. This magnet system is the result of a long-term partnership project jointly funded by the U. S. Department of Energy - Office of Basic Energy Science and the National Science Foundation. Science experimentation inside the magnet started in December 2006 at the NHMFL Pulsed Field Science Facility located at Los Alamos National Laboratory. Repeated, non-destructive operation of the system with original components is continuing in the 85 T to 90T range. The system will eventually combine a nominal 40 T platform field produced by a controlled-waveform generator-powered long-pulse magnet with a nominal 60 T field generated by a capacitor-bank powered pulsed insert magnet to produce the rated field. Milestone non-destructive operation to 88.9 T was achieved in October 2006. This paper will present an overview of the generator driven outsert magnet system together with the high-field pulsed insert magnet's design and construction. We will review commissioning and performance data through summer of 2007. Criteria for increasing the systems maximum field performance will also be reviewed addressing the goal to increase operating field level (in support of experiments) to 95 T and then to 100 T.
