1. 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
2. From Particle-Production Cross Sections to KERMA and Absorbed Dose for the Case 96 MeV n-12C Interactions
Sammanfattning : Neutron-carbon interactions have been studied with a focus on charged-particle production of relevance to radiation protection and medical applications, such as cancer therapy. The measurements have been performed using the particle-detection setup, MEDLEY, and the 96 MeV neutron beam at the The Svedberg Laboratory in Uppsala. LÄS MER
3. Fast neutron dosimetry : a study of basic dosimetric properties of fast-neutrons for external beam radiotherapy and problems associated with corrections of measured charged particle cross-sections
Sammanfattning : Basic dosimetric properties of fast-neutron beams with energies ≤80 MeV were explored using Monte Carlo techniques. Elementary pencil-beam dose distributions taking into account transport of all relevant types of released charged particles (protons, deuterons, tritons, 3He and a particles) were calculated and used to derive several absorbed dose distributions.

4. Dosimetry and radiation quality in fast-neutron radiation therapy : A study of radiation quality and basic dosimetric properties of fast-neutrons for external beam radiotherapy and problems associated with corrections of measured charged particle cross-sections
Sammanfattning : The dosimetric properties of fast-neutron beams with energies ≤80 MeV were explored using Monte Carlo techniques. Taking into account transport of all relevant types of released charged particles (electrons, protons, deuterons, tritons, 3He and α particles) pencil-beam dose distributions were derived and used to calculate absorbed dose distributions.

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