"High Magnetic Fields and Physics: Issues in the Design and Construction of
Superconducting Magnets"
Cesar Luongo
Jefferson Lab
Abstract: Many fields of Physics research (notably Condensed Matter Physics
and Particle Accelerators/Detectors) rely heavily in the availability of high
magnetic fields, usually generated by superconducting magnets. There has been
a dual thrust at play for well over a century, in which the need for discovery
of new Physics pushes the technology of superconducting magnets to achieve more
(higher, bigger, better), while the technology improvements themselves have
opened doors to the discovery and study of new phenomena. This talk will walk
through that interaction between Physics and Magnet Technology by presenting
some of the Nobel Prizes awarded in the past 100 years in which high magnetic
fields were central to the discovery process. Different types of magnets will
be described (resistive, hybrid, superconducting, and pulsed), and the main
design drivers discussed for each one of them. In the second part of the talk,
the focus will be on superconducting magnets, what are the main trade-offs when
designing such magnets, what are the performance and cost drivers, and why they
tend to be complex and expensive. A few applications of superconducting magnets
will be presented (MRI, fusion, etc.).
