Abstract

Test results of the threshold aerogel Cherenkov counter system with n=1.05 intended for particle separation are presented. The system is constructed for SND detector which is taking data at VEPP-2000 e⁺e⁻ collider. The measurements have been done using particles from e⁺e⁻→e⁺e⁻ and e⁺e⁻→μ⁺μ⁻ reactions. The average signal from electrons is 3.5 photoelectrons.
