    Abstract

    We present new results on the development of larger arrays (presently 72 channels, goal of multiple units of 160 channels) of superconducting LC filters. The a-Si:H based resonators show a quality factor above 10.000. The latest design utilizes oppositely wound planar coil pairs which enable close packing with low magnetic cross talk. We present results on the obtained center frequency distribution within the range of 1 to 3 MHz.
