The results of a study of the properties of aerogel manufactured at the Laboratory of Nuclear Problems, Joint Institute for Nuclear Research, are presented. The technology of the production of aerogel samples and the optical characteristics of these samples are briefly described. A formula relating the refractive index of the aerogel to its density with regard to the dispersion of light is analyzed. The results of testing of an aerogel threshold Cerenkov counter are presented. Testing was performed using a beam of charged particles with momenta p ranging from p = ∼ 0.4–2.5 GeV/ с. The efficiency of pion detection with p ≥ 1 GeV/ с was ∼97%; the efficiency of proton detection with p ≤ 2.5 GeV/ c, ∼4%. [ABSTRACT FROM AUTHOR] |
