The detection system consists of up to four thin-film YBCO nanobridges fed by planar double-slit antennas covering the frequency range from 140 GHz up to 1 THz. We present first results obtained at the ANKA storage ring and at Diamond Light Source during operation of two and four frequency-selective YBCO detectors, respectively.
