  2. 1. Studies of Heavy Ion Induced Desorption in the Energy Range 5-100 MeV/u

    Author : Emma Hedlund; Lars Westerberg; Oleg Malyshev; Manfred Leisch; Uppsala universitet; []
    Keywords : Physics; Heavy Ion Induced Desorption; Ultra High Vacuum; NEG Coating; Heavy Ion Accelerators; Test Particle Monte-Carlo; Gas Flow; Throughput; Laser Refractometry; Metrology; Fysik;

    Abstract : During operation of heavy ion accelerators a significant pressure rise has been observed when the intensity of the high energy beam was increased. The cause for this pressure rise is ion induced desorption, which is the result when beam ions collide with residual gas molecules in the accelerator, whereby they undergo charge exchange. 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

  7. 5. Experimental studies of particle production in ultra-relativistic heavy ion collisions

    Author : Pål Nilsson; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pad chambers; PHENIX; WA98; phi-meson; tracking; single particle spectra; heavy-ion collisions; inverse slope parameters; particle production; RHIC; charged particle multiplicity; pad readout; SPS; Physics; Fysik; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:2001:Nilsson;

    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
