摘要
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 temporal development of a signal inside the gap in three different modes: avalanche, saturated avalanche and streamer. The space charge field is shown to be very important for the initiation of a streamer signal. The simulation can also predict existence of a precursor avalanche signal before appearance of a strong streamer signal in agreement with experimental results. (C) 2010 Elsevier B.V.
