T. Iijima et al., AEROGEL CHERENKOV COUNTER FOR THE BELLE EXPERIMENT, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 379(3), 1996, pp. 457-459
In the BELLE experiment at KEKB, a threshold Cherenkov counter system
based on silica aerogels will be used to provide pi/K separation in th
e momentum region from 0.8 to 3.5 GeV/c. The detector design, recent p
rogress in R&D and results of beam tests are reviewed.
