A start trigger detector for the ALICE spectrometer

A fall-back option of the T0 start trigger detector was developed for the ALICE setup that was intended for the study of quark-gluon plasma with the LHC accelerator (CERN). The Monte Carlo simulation with the PYTHIA program was performed for a detector incorporating two symmetrical arrays of 12 Cere...

description A fall-back option of the T0 start trigger detector was developed for the ALICE setup that was intended for the study of quark-gluon plasma with the LHC accelerator (CERN). The Monte Carlo simulation with the PYTHIA program was performed for a detector incorporating two symmetrical arrays of 12 Cerenkov counters, each composed of 26-mm- diameter Hamamatsu R5505 phototubes with fine-mesh dynodes and a quartz radiator 3 cm in length and 26 mm in diameter. Its simulated detection efficiency for p-p collisions exceeded 88%. A prototype Cerenkov counter, consisting of a R3432-01 (similar to R5505) phototube and a quartz radiator with dimensions of 25*30*12 mm, was tested in a beam of pions and protons with a 1.19-GeV/c-momentum. The time resolution in the 1-200 dynamic range was better than 50 ps. (3 refs).
