Abstract The Ring-Imaging Cherenkov (RICH) and the Time-of-Flight (ToF) systems provide identification of charged particles for the PHENIX central arm. The RICH is located between the inner and outer tracking units and is one of the primary devices for identifying electrons among the very large number of charged pions. The ToF is used to identify hadrons and is located between the most outer pad chamber (PC3) and the electromagnetic calorimeter. A Time Zero (T0) counter that enhances charged particle measurements in p–p collisions is described. Details of the construction and performance of both the RICH, ToF and T0 are given along with typical results from the first PHENIX data taking run.

Abstract The RICH detector of the PHENIX experiment at RHIC is currently under construction. Its main function is to identity electron tracks in a very high particle density, about 1000 charged particles per unit rapidity, expected in the most violent collisions at RHIC. The design and construction status of the detector and its expected performance are described.

Abstract The PHENIX experiment at RHIC is primarily a lepton and photon detector. Electron detection takes place in the two central arms of PHENIX, with the primary electron identifier in each arm being a ring imaging Cherenkov detector. This paper contains a description of the two identical RICH detectors and of their expected performance.

Abstract A new front-end electronics (FEE) for PHENIX Ring Imaging Cherenkov Detector (RICH) has been developed. It consists of custom-made Backplane, Controller module, Readout module and AMU/ADC module, which are capable of processing signals from 5120 Photo-Multiplier Tubes (PMTs). Several tests have been carried out, and RICH FEE was proved to satisfy the requirement of PHENIX experiment. The charge spectrum due to single photo-electron was successfully observed as well.
