|Los Alamos National Lab has been working to develop high-volume
production processes for making a thin, flexible tape that operates as
a superconductor at liquid nitrogen temperatures and can carry 3 million amps per cm2.
This video crams a lot of information into one brief video, with quick
shots of each stage of the production process, including the
preparation of the base nickel alloy tape, the ion beam-assisted
deposition of magnesium oxide and the pulsed-laser deposition of
yttrium barium copper oxide/samarium barium copper oxide. Besides
demonstrating some of the progress being made at LANL, this is a good
introduction to a lot of processes that are brought to bear in this
type of manufacturing.
