Abstract
A new threshold Cherenkov detector has been built for the detection of charged pions in the focal plane of a magnetic spectrograph. Silica aerogel with refractive index of n = 1.05 is applied as a radiator. The detector exhibits a very high detection efficiency for pions with momenta ⩾ 900 MeV / c . Using two Cherenkov detectors in series a very high pion suppression factor of 10 5 was achieved.
