1. Net-Charge Fluctuations in Ultra-Relativistic Nucleus-Nucleus Collisions
Sammanfattning : PHENIX is one of four experiments at the Relativistic Heavy-Ion Collider, RHIC. The high-energy heavy-ion collisions provided by this accelerator offer the possibility to study nuclear matter at high temperature and density. The high multiplicity of particles produced in these collisions puts high demands on detector performance. LÄS MER
2. Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design
Sammanfattning : Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the ~10 MeV regime. LÄS MER
3. Experimental studies of particle production in ultra-relativistic heavy ion collisions
Sammanfattning : 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. LÄS MER
4. Studies of Nuclear Matter under Extreme Conditions: Heavy-Ion Interactions at Ultra-Relativistic Energies
Sammanfattning : The charged particle production in ultra-relativistic nucleus-nucleus collisions in the energy range 4-200 A GeV has been studied. Two different experimental techniques have been utilized: nuclear emulsions and Multi-Step Avalanche Chambers. LÄS MER
5. Jet-wind interaction in neutron star mergers
Sammanfattning : Besides being sources of gravitational waves, there has been evidence that neutron starmergers release neutron-rich material suitable for the production of heavy r-process nuclei.The radioactive decay of these freshly synthesised elements powers a rapidly evolvingthermal transient, the “macronova” (also known as “kilonova”).
