    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RHIC; pad readout; electronic; chip-on-board; tracking; heavy-ion collisions; freeze-out temperature; delta resonance; SPS; WA98; PHENIX; Fysik; coherent peripheral; multiplicity; Physics; Fysicumarkivet A:2001:Silvermyr;

    Sammanfattning : High-energy heavy-ion collisions provide a unique tool for the study of nuclear matter as a function of temperature and density. WA98 at the CERN SPS recorded data with a 158 A GeV Pb beam on a Pb target in 1996. To cope with the high charged-particle density, a tracking system based on high granularity multi-step avalanche detectors was developed. LÄS MER
