Abstract
First results from a new RICH detector, operating in an experiment cur rently taking data - Fermilab E781 (SELEX), are presented. The detecto r utilizes a matrix of 2848 phototubes for the photocathode. In a 650 GeV/c pi(-) beam the number of photons detected is 14 per ring, giving a figure of merit N-0 of 106 cm(-1). The ring radius resolution obtai ned is 1.2%. Results showing the particle identification ability of th e detector are discussed. (C) 1998 Elsevier Science B.V. All rights re served.
