    Abstract : This thesis is about high energy heavy ion physics. Two major experiments, the WA98 at CERN and the PHENIX at Brookhaven National Laboratory, are described. Results from data analysis from both experiments are presented. The WA98 chapter presents particle identification methods and phi-meson measurements. READ MORE

  4. 2. Aspects of Hadron Production in High-Energy Heavy-Ion Physics

    Author : David Silvermyr; Partikel- och kärnfysik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Tracking Chambers with Two-Dimensional Readout used for Extraction of Particle Production Ratios in High Multiplicity Pb+Pb Collisions at 158 A GeV

    Author : Tomas Svensson; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; position resolution; wire chamber pixel readout; pad readout; tracking; multi-step avalanche chamber; Fysik; Physics; particle ratios;

    Abstract : Heavy-ion collisions at high energies calls for new technical solutions to cope with the very high multiplicities of produced particles. In this thesis the design and development of two types of tracking chambers for high multiplicity environments are presented. READ MORE
