Measuring Attenuation In Signal Propagation In Resistive-Plate Chambers

This study simulated and measured the attenuation in signal propagation in a Resistive-Plate Chamber (RPC) and analysed it as a loss of signal charge during propagation along the readout strip. The measurement results revealed a strong correlation between the quantified rate of attenuation in charge and the surface resistivity of the graphite layer of the RPC. The rates of attenuation in amplitude and frequency of the signal were also measured, following which the mechanism of attenuation in signal propagation was discussed. Potential methods to mitigate its effects were studied using simulations.
