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%. Results showing the particle identification ability of the detector are discussed.
