Abstract:

This note describes an analysis of time information in four BCAL cosmics runs that were taken at JLab in 2006. Time resolutions of segments that were read out with Philips XP2020 photomultipliers were found to be in the 0.3-0.6 ns range, while the time resolutions of the segments with Burle 8575 PMT readout are in the 0.5-1.3 ns range. Separation of statistical and floor terms of the time resolution is described.
