β¦ Synopsis
Resistive Plate Chambers (RPCs) are widely used in high energy physics. While avalanche mode operation is mandatory in high rate environments (ATLAS and CMS experiments at LHC), streamer mode operation is often preferred in low rate applications because of the high signal amplitude. Typical mixtures for streamer operation are composed of Argon, Tetrafluoroethane and Isobutane, with additions of SF 6 below 1% to reduce the charge delivered in the gas. In this paper, results about the streamer properties observed with different mixtures are presented.

Simulation of a streamer initiation inside the gas gap of a trigger Resistive Plate Chamber (RPC) has numerically been performed using a minimal streamer model including transport equations and Poisson equation for electrons, negative and positive ions. The simulation can well predict spatial and te
