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