Abstract：
In this paper the principle of self-quenching streamer (SQS) discharge and construction of SQS detectors are described. The main performances of our SQS detectors are: Pulses with a rise time of 3 to 5 ns reach 100 mV into 50Ω with a decay time of 30 ns. The plateau in counting rate vs voltage is about 700 V. The efficiency for registing charged particles is 100%. The rate capability of SQS tubes is better than 10³ per second per millimeter along the wire. The localized dead time is obout 10 μs/2 mm which equals a dead zone of 2 μs.cm.
Some examples of using our SQS detectors in areas of low-energy nuclear technology, health physics and environment protection are given.
