摘要: The paper is devoted to the development of Cherenkov counters based on Aerogel, wavelength SHIfters and PHotomultiplier tubes (ASHIPH) for SND detector at VEPP-2000. ASHIPH counter system designed. will separate p K mesons in momentum range from 300 900 MeV=c: Optical properties aerogel samples with refraction index 1.13 are measured results presented. As photodetectors, microchannel plate photomultipliers multialkali photocathodes used. Monte Carlo simulation predicts more than 7 photoelectrons a relativistic particle. r 2002 Elsevier Science B.V.
