In 2014 the fully installed ASHIPH (Aerogel, SHifter, PHotomultiplier) system began its operation in the KEDR experiment at the VEPP-4M e+e−-collider. The system contains 1000liters of aerogel with refractive index n=1.05 in 160 counters that are arranged in two layers. Cherenkov light collection is preformed by means of wavelength shifters (WLS). 160Micro-Channel Plate (MCP) PMTs with multialkali photocathode are used as photodetectors. Efficiency of relativistic particles detection was measured with e+e−→e+e− events and cosmic muons. Detection efficiency for under-threshold particles was measured with cosmic muons. From these data π/K-separation of 4σ at the momentum 1.2GeV/c was obtained.
