“…This mode delivers [4] large amplitude saturated signals, and is less sensitive than the avalanche or proportional mode [5] to electromagnetic noise, to changes in the environment conditions and to mechanical deformations of the detector. On the other hand the larger rate capability achievable in avalanche mode [6] is not needed in a cosmic ray experiment.…”

“…This research resulted in relevant improvements of the RPC performance in addition to a better understanding of the detector physics [1]. However, the streamer mode operation, due to the advantage of producing large, saturated and easy to discriminate signals is still of interest for several experiments [2] where the rate capability requirements are not particularly strong.…”

“…The main difference between the avalanche and the streamer mode operation is the amount of delivered charge that, although gas dependent, is usually several tens of times larger in streamer mode [1]. The consequences for the streamer operation are: a lower rate capability, which is limited by the maximum current that can flow across the high resistivity electrodes and a higher energy released in the gas.…”

In the present paper we describe a search for gases that allow to reduce the energy of the electrical discharge produced in Resistive Plate Chambers (RPCs) operated in streamer mode, by reducing both the operating voltage and the released charge. This can be achieved, with current gas mixtures of argon, tetrafluoroethane (TFE) and isobutane, by reducing the total amount of quenching components (TFE+isobutane) down to 10-15% and compensating for the lower gas quenching power with the addition of small amounts of SF 6 : We show here that SF 6 ; even for concentrations as low as 1% or less, has a strong effect in reducing the delivered charge in low quenched gases and allows to achieve a proper working mode of the RPC even at voltages as low as 4-5 kV over a 2 mm gas gap. r

Abstract. Multiwire proportional chamber is a conventional technique to study radiation in general, and cosmic rays in particular. To study cosmic rays, it was planned, designed, constructed, characterized, and tested a four channel mini wire chamber, based on two 3 cm × 3 cm × 0.6 cm Aluminum frames, two 3 cm × 3 cm × 0.6 cm plastic frames, two 3 cm × 3 cm × 0.3 cm Aluminum frames, two electronic planes each with two Tungsten Gold plated 1 mil diameter wires, parallel and 1 cm apart each other at 25 g stretched -each plane was 90 o rotated each other in the final assemble-and two Aluminum foil window to define the gas volume; it was operated with Argon 90%-CH4 10% gas mixture at 1 atmosphere and ambient temperature (20 o C in the average). It is presented technical details, results on characterization, and preliminary results on cosmic rays detection.
