The rich counter in the CERN hyperon beam experiment

The RICH counter of experiment WA89 at the CERN-SPS is described. The radiator is nitrogen at atmospheric pressure. Drift chambers filled with TMAE-loaded ethane are used as photon detectors. The maximum drift path is 41 cm. The spatial resolution of the chambers is better than 2 mm and 14 photo-ele...

More Information
Summary:The RICH counter of experiment WA89 at the CERN-SPS is described. The radiator is nitrogen at atmospheric pressure. Drift chambers filled with TMAE-loaded ethane are used as photon detectors. The maximum drift path is 41 cm. The spatial resolution of the chambers is better than 2 mm and 14 photo-electron per ring have been detected, on average.
