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.

A front-end readout system with a custom backplane and custom circuit modules has been developed for the RICH subsystem of the PHENIX experiment. The design specifications and test results of the backplane and the modules are presented in this paper. In the module design, flexibility for modification is maximized through the use of Complex Programmable Logic Devices. In the backplane design, source synchronous bus architecture is adopted for the data and control bus. The transfer speed of the backplane has reached 640 Mbyte/s with 128-bits data bus. The total transaction time is estimated to be less than 30 /spl mu/s per event when this system is applied to the experiment. This result indicates that the performance is satisfied with the requirements of the PHENIX experiment.

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.
