Comparison of Timing Properties of Glass Multigap RPCs with 0.3 and 0.6   mm Subgap Width
  Timing characteristics of two multigap RPCs were compared. One had four subgaps 0.3 mm wide and the other - two subgaps 0.6 mm wide. 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 (2x0.6mm) counter was found to be considerably lower than for the (2x(2x0.3mm)) one.
