چکیده
We present preliminary results from a test beam run of CLEO III RICH modules. The system consists of LiF radiators and multiwire proportional chambers containing a mixture of CH4 and TEA gases. The radiators were both at and \sawtooth." The data were taken in a beam dump at Fermilab. We will discuss the chamber stability, electronics, the number of photons observed for both radiators, the angular resolution per photon and the angular resolution per track.

Performance of the CLEO III LiF-TEA Ring Imaging Cherenkov Detector in a High Energy Muon Beam
The CLEO III Ring Imaging Cherenkov detector uses LiF radiators to generate Cherenkov photons which are then detected by proportional wire chambers using a mixture of CH4 and TEA gases. The first two photon detector modules which were constructed, were taken to Fermilab and tested in a beam dump that provided high momentum muons. We report on results using both plane and “sawtooth” shaped radia...

The CLEO-III Detector upgrade for charged particle identification is discussed. The RICH design uses solid LiF crystal radiators coupled with multi-wire chamber photon detectors, using TEA as the photosensor, and low-noise Viking readout electronics. Results from our beam test at Fermilab are presented. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ...
متن کاملCLEO III, A Dectector To Measure Rare B Decays and CP Violation
The symmetric ee collider CESR is undergoing a series of upgrades allowing for luminosities in excess of 2×10cms. The most important goals of the upgrade are precision measurement of standard model parameters Vcb, Vub, Vtd/Vts, fDs, and searching for CP violation and standard model violations in rare B decays. A new detector upgrade, called CLEO III, has started which includes a new silicon-wir...
متن کاملPerformance of the LiF-TEA Ring Imaging CherenkovDetector at CLEO
We describe the particle identification capability of the CLEO RICH system. This system consists of a 1 cm thick LiF radiator coupled to a photon detector that uses wire proportional chambers filled with a mixture of CH4 and TEA. We discuss the yield of photoelectrons observed per ring and the angular resolution. We show the efficiencies achieved for particle identification and the associated f...
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 ...
