BTG wins DOE SBIR Phase I Award
Beam positioning monitor based on large area HTS pickup coils
Brookhaven Technology Group (BTG) and STAR Cryoelectronics (STAR) will design and develop a long-base high-temperature superconducting gradiometer instrument capable of detecting position of a particle beam as low as 1 nA. The technology relies on two key innovations. First, the sensing coil structure will be laser-machined from extra-wide (45 mm) second-generation superconducting tapes. Second, the sensing coils will be magnetically coupled to a high-performance quantum interference sensor, developed by STAR. The technology is expected to deliver high sensitivity, > 100 micron beam position error, and low cost of ownership.
