Abstract :
High temperature superconductors (HTS) have the potential to change the design and operation of future particle accelerators beginning with the design of high performance interaction regions. HTS offers two distinct advantages over conventional low temperature superconductors (LTS)-they retain a large fraction of their current carrying capacity (a) at high fields and (b) at elevated temperatures. The Superconducting Magnet Division at Brookhaven National Laboratory (BNL) has embarked on a new R & D program for developing technology needed for building accelerator magnets with HTS. We have adopted a "React and Wind" approach to deal with the challenges associated with the demanding requirements of the reaction process. We have developed several "conductor friendly" designs to deal with the challenges associated with the brittle nature of HTS. We have instituted a rapid turn around program to understand and to develop this new technology in an experimental fashion. Several R & D coils and magnets with HTS tapes and "Rutherford" cables have been built and tested. We have recently performed field quality measurements to investigate issues related to the persistent currents. In this paper, we report the results to date and plans and possibilities for the future.
