A low resistance superconducting switch for use in initiating transfer of energy from an inductive energy storage coil has been constructed and tested at Los Alamos Scientific Laboratory. The switch will be used in series with a mechanical circuit breaker to reduce the current through the breaker prior to its opening. Both mechanical breaker and switch are immersed in liquid helium. Opening the switch before the mechanical breaker will reduce arcing and burning of the mechanical breaker contacts and reduce the rate at which the heat generated during the switching operation is deposited into the helium bath. A detailed description of the switch design and construction is given as well as the initial design parameters and test results. A circuit diagram of the switching scheme and a discussion of the circuit is also given. (auth)
