National High Magnetic Field Laboratory
Overview
The National High Magnetic Field Laboratory (NHMFL), often referred to as the MagLab, is a premier research facility dedicated to advancing the science and technology of high magnetic fields. It is the largest and highest-powered magnet laboratory in the world, providing scientists and engineers with the tools necessary to conduct cutting-edge research across a wide array of disciplines, including physics, chemistry, biology, and materials science.
Founded in 1990 and headquartered in Tallahassee, Florida, the NHMFL is a collaborative effort between Florida State University (FSU), the University of Florida (UF), and Los Alamos National Laboratory (LANL). The laboratory is funded primarily by the National Science Foundation (NSF) and the State of Florida, and it serves as a national resource for researchers from around the globe.
History and Development
The origins of the NHMFL trace back to the late 1980s when the need for a centralized facility to support high magnetic field research became apparent. Prior to its establishment, high magnetic field research in the United States was fragmented across various smaller labs, limiting the scope and scale of potential scientific breakthroughs. In response, the NSF initiated a competitive process to create a centralized national laboratory.
Florida State University, in collaboration with the University of Florida and Los Alamos National Laboratory, successfully proposed the establishment of the NHMFL. The proposal emphasized the creation of a facility that would not only provide access to high magnetic fields but also foster interdisciplinary collaboration and innovation. The laboratory officially opened its doors in 1994, marking a significant milestone in the advancement of magnetic field research.
Facilities and Infrastructure
The NHMFL boasts an impressive array of facilities designed to support a wide range of scientific investigations. The laboratory's infrastructure is divided into several key components:
