Superconductivity to the rescue

There are many large, useful electromagnets in service in laboratories throughout the world that are faced with common problems: i.e., incipient failure due to age, ever present desire for higher fields, and staggering escalation of power costs. Conventional rewind is generally not feasible due to magnet configuration and continuing high operating costs. A unique engineering approach is presented for the modification of existing exciting coils to operate in a superconducting mode using proven state of the art techniques and considerable cost savings over the fabrication of new superconducting coil packages using more conventional coil packaging. Typical cost analyses show the attractive use of such proposals
