Abstract: To—the fast timing and trigger detector for the ALICE experiment at CERN LHC—is described. Performance of the TO prototype measured with a mixture of 6 GeV/c negative pions and kaons is given. The best time resolution (28 ps r.m.s.) was reached with a radiator diameter matching that of the photocathode. The results for all the tested radiator sizes are considerably better than 50 ps—the minimum requirement for the ALICE experiment. [ABSTRACT FROM AUTHOR]
