Overview

abstract

• First results from a new RICH detector, operating in an experiment currently taking data - Fermilab E781 (SELEX), are presented. The detector utilizes a matrix of 2848 phototubes for the photocathode. In a 650 GeV/c π- beam the number of photons detected is 14 per ring, giving a figure of merit N0 of 106 cm-1. The ring radius resolution obtained is 1.2%25. Results showing the particle identification ability of the detector are discussed. © 1998 Elsevier Science B.V. All rights reserved.
