A threshold Cherenkov detector for K+/pi+ separation using silica aerogel
A threshold Cherenkov detector for K+/pi+ separation using silica aerogel
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 >= 900MeV/c....

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 >= 900MeV/c. Using two Cherenkov detectors in series a very high pion suppression factor of 10(5) was achieved. (C) 2008 Elsevier B.V. All rights reserved. |
