An environmental safe gas mixture for resistive plate chambers operated at low pressure

A detailed study of the performance of resistive plate chambers, operated in streamer mode and filled with ozone safe gas mixtures, is reported; efficiency, time resolution, strip multiplicity, etc., have been measured both at atmospheric and at low pressure, to simulate a possible use of these detectors at high altitude.
