Abstract
A RICH detector was used during the 1996/7 fixed target run at Fermilab in experiment E781 - SELEX. The detector utilizes a matrix of 2848 phototubes for the photocathode. The figure of merit, N-o, has been measured to be in excess of 100 cm(-1). The ring radius resolution for multitrack events has been measured to be 1.8 mm, which gives K/pi. separation on a 2 sigma level up to a momentum of 165 GeV/c, and p/pi separation up to 320 GeV/c. We wil l describe the design of the detector, discuss the stability during operati on, and report on achieved results (C) 1999 Elsevier Science B.V. All right s reserved.
