Abstract :
Properties of discharges in a 2 mm glass Resistive Plate Chamber were investigated using the light amplifier for optical pictures and the digital scope for waveforms of induced pick-up signals. Multiple discharges were observed for different tetrafluoroethane-based gas mixtures both in ‘avalanche’ and ‘streamer’ modes. Multiple discharges substantially increase the spatial size of the initial discharge caused by a through-going particle ionisation. Average spatial characteristics and typical optical pictures are presented. Space–time relationships for the streamer do not show any prominent dependence.
