Abstract :
The design and performance of a detector system for tracking charged particles in an environment of high track density and rates up to 1 MHz are described. The system operates in the forward spectrometer of the Brookhaven National Laboratory heavy ion experiment E814 and uses principles of general interest in high-rate, high-multiplicity applications such as at the Relativistic Heavy Ion Collider or the Superconducting Supercollider. The system is required to perform over a large dynamic range, detecting singly charged particles as well as fully ionized relativistic 28Si. Results on gas gain saturation, δ-ray suppression, and overall detector performance in the presence of a 14.6-GeV/nucleon 28Si beam and a 14-GeV proton beam are presented
