The Cleo Rich Detector
We describe the design, construction and performance of a Ring Imaging Cherenkov Detector (RICH) constructed to identify charged particles in the CLEO experiment. Cherenkov radiation occurs in LiF crystals, both planar and ones with a novel “sawtooth”-shaped exit surface. Photons in the wavelength interval 135–165 nm are detected using multi-wire chambers filled with a mixture of methane gas an...
متن کاملThe Na62 Experiment
— We discuss the NA62 experiment which aims at the search for phenomena beyond the Standard Model (SM) by measuring the ratio RK = Γ(K ± → eν(γ))/Γ(K → μν(γ)) and the ultra rare decay K → πνν. First, we summarize the status of the RK analysis, based on ∼ 40% of the 2007-2008 NA62 data set, then, we describe the NA62 proposal to measure the branching ratio of the very rare decay K → πνν and we g...
متن کاملThe CLEO III RICH Detector
In the past 20 years of its existence, the CLEO detector has been associated with many discoveries and precision measurements of heavy flavour physics. The latest generation of the detector, the CLEO III, has been upgraded. One of the new features of the CLEO III detector is it’s particle identification system, the Ring Imaging CHerenkov (RICH) detector. The basic principle of the differential ...
متن کاملThe SELEX Phototube RICH Detector
In this article, construction, operation, and performance of the RICH detector of Fermilab experiment 781 (SELEX) are described. The detector utilizes a matrix of 2848 phototubes for the photocathode to detect Cherenkov photons generated in a 10m Neon radiator. For the central region an N0 of 104 cm , corresponding to 13.6 hits on a β = 1 ring, was obtained. The ring radius resolution measured ...
متن کاملA detector for the measurement of the ultrarare decay K→ πνν̄: NA62 at the CERN SPS
The NA62 experiment at CERN aims at the very challenging task of measuring with 10% relative error the Branching Ratio of the ultra-rare decay of the K+ into π+νν̄ , which is expected to occur only in about 8 out of 1011 Kaon decays. This will be achieved by means of an intense hadron beam, an accurate kinematical reconstruction and a redundant veto system for identifying and suppressing all spu...
