K. Borer et al., TIME-OF-FLIGHT MEASUREMENTS WITH HADRONIC SHOWERS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 344(3), 1994, pp. 529-536
We present the results obtained from measurements of the arrival time
of hadronic particles in a segmented scintillator-uranium calorimeter
which was equipped with dedicated time of flight scintillator hodoscop
es in depths of 0.75, 1.5, 2.25, 3.0 and 4.5 lambda(int). Gaussian sha
ped time resolutions with sigma almost-equal-to 90 ps were obtained wi
th pi- beams of 30 GeV/c and 70 GeV/c momentum. We discuss to what ext
ent non-Gaussian tails can be removed while keeping a reasonably high
efficiency.
