Abstract :
In the BELLE experiment at the KEK B-factory, a threshold aerogel Cherenkov counter, with refractive index from 1.010 to 1.030, is used to provide π/K separation in the momentum region up to 3.5 GeV/c. The detector system has been constructed, installed into the BELLE detector, and then commissioned with cosmic rays and beams. This paper presents a brief explanation of the detector system and its performance obtained in early BELLE physics runs.
