Streamer counter

The design and specifications of gas-filled multiwire detectors utilized in a magnetic-free hadron spectrometer are described. The detectors represent a system of flat multiwire electrodes with 2 mm pitch of winding signal wires and 2 mm gas gap. The detector filled with ''magic gas'' (75% Ar+24.5% CuH10+0.5% CF3Br)+4% methylal operates in the ''self-quenching'' streamer regime and may be called ''short-streamer counter''. The signal from the counter after slight preamplification was supplied to standard channels of the magnetic-free hadron spectrometer electronics intended for operation with scintillation counters
