| Comparison of Timing Properties of Glass Multigap RPCs with 0.3 and 0.6 mm Subgap Width | ||
| Protvino, 2002.- p.9, figs. 7, refs.:9. | ||
Two glass RPCs with symmetrical read-out scheme --- (2$\times$(2$\times$0.3mm)) and (2$\times$0.6mm) --- were constructed and tested at CERN PS T10 beam. Specially developed electronics was used. Electronics resolution convoluted with measured charge spectra at operating point was estimated as about 65 ps. The best time resolutions obtained at low counting rate were 75 ps for the 0.3 mm subgap and about 125 ps for the 0.6 mm one, after slewing corrections. The rate capability of the (2$\times$0.6mm) counter was found to be much worse than for the (2$\times$(2$\times$0.3mm)) one.
