The various devices currently being constructed for electric power and
high-energy physics applications demand different performance, cost,
and geometry requirements of high-temperature superconductors. At Inte
rmagnetics General Corporation, four types of high-temperature superco
nductors (power-in-tube Bi-2223, surface-coated Bi-2212, power-in-tube
Bi-2212, and YBa2Cu3Ox) are at various stages of development to meet
this demand.
