Abstract :
The PHOBOS experiment is well positioned to obtain crucial information about relativistic heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC), combining a multiplicity counter with a multi-particle spectrometer. The multiplicity arrays will measure the charged-particle multiplicity over the full solid angle. The spectrometer will be able to identify particles at mid-rapidity. The experiment is constructed almost exclusively of silicon pad detectors. Detectors of nine different types are configured in the multiplicity and vertex detector (22,000 channels) and two multi-particle spectrometers (120,000 channels). The overall layout of the experiment, testing of the silicon sensors and the performance of the detectors during the engineering run at RHIC in 1999 are discussed.
