The 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 کاملThe 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 کاملSELEX RICH Performance and Physics Results ∗
SELEX took data in the 1996/7 Fixed Target Run at Fermilab. The excellent performance parameters of the SELEX RICH Detector had direct influence on the quality of the obtained physics results.
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 کاملRing Reconstruction in the CBM RICH detector
In this contribution we will present innovations and improvements which have been developed for ring reconstruction in the CBM RICH detector. A RICH ring recognition algorithm based on the Hough Transform (HT) [1, 2] was rewritten improving the speed and ring finding efficiency. The HT is now optimized for the Hamamatsu PMT H8500-03 (22 hits per electron ring). Using the Hamamatsu PMT did not r...
