Multi-Strip Read-Out in RPCs: Cross-Talks and Cluster Size.
Protvino, 1999.-p.19, figs.13, refs.:14.


Study of cross talks and their correlation with an observed cluster size for multi-strip RPC read-out was carried out using the beam and Inner Spark Pulser data. The marked influence of the surface resistivity of the HV electrode graphite coating on the induced charge spread among the read--out strips was observed. The waveforms and relative amplitudes of the CT signals were studied for different discharge positions across the strips. No cross talks and cluster size reduction was obtained for the strip panel with tiny screening strips as compared with the ordinary panel.
