Abstract :
We measured spatial distribution of induced charge on the thin readout wires on RPC operated in avalanche mode with the gas mixture containing SF6, C4H10, and C2H2F4. We found that the induced charge spread on the wires was ~6 mm. According to the time properties of the induced charge, there was a delayed component of the signal and they supposed to be due to propagation of induced charge on a wire to adjacent one. Considering the effect, the intrinsic charge spread by an avalanche was found to be ~2 mm.
