Classical models of heavy ion collisions
We study the effects of the nuclear equation of state (EOS) on intermediate energy heavy-ion collisions using classical microscopic models. The role of the EOS on the disassembly of expanding, hot nuclear matter, as well as the experimental data on multi-fragmentation and collective flow phenomena, …

Heavy-Ion Interaction Models for Radiation Transport
<p>This dissertation is concerned with finding the values for the nuclear cross sections used in the Boltzmann equation for space radiation transport and dose estimates. An extraordinary number of cross sections are required because of the large number of ion types and their extensive energy range, …

Monte Carlo simulations for heavy ion dosimetry
Water-to-air stopping power ratio ( ) calculations for the ionization chamber dosimetry of clinically relevant ion beams with initial energies from 50 to 450 MeV/u have been performed using the Monte Carlo technique. To simulate the transport of a particle in water the computer code SHIELD-HIT v2 …

Pion Production in Relativistic Heavy Ion Collisions
In der vorliegenden Arbeit wird die Pionenproduktion verschiedener Systeme (Ca+Ca, Ru+Ru, Zr+Zr und Au+Au) bei drei verschiedenen Strahlenergien (400, 1000 und 1500 AMeV) untersucht. Die Experimente wurden mit dem FOPI Detektor am Schwerionen Synchrotron (SIS) der Gesellschaft fuer …

Hadronization in Ultra-Relativistic Heavy Ion Collisions
… proposed mechanisms for the dynamical hadronization transition in both ultra-relativistic heavy-ion collisions and the very early universe. We develop very general criteria for hydrodynamical stability and apply them to a number of proposed solutions. We find that the hadronization is …

Pattern recognition analysis on heavy ion reaction data
… in the analysis of nucleus-nucleus collisions is to get information on the value of the impact parameter b. This work consists in the application of pattern recognition techniques aimed at associating values of b to groups of events. To this end, a support vec- tor machine (SVM) classifier …

Rescattering and fluctuations in ultrarelativistic heavy-ion collisions
We study ultra-relativistic heavy-ion collisions using, as far as possible, known physics and simple assumptions. One focus is on the measurable effects of rescattering of produced particles in the colliding nuclei. Two models for proton-nucleus collisions are presented, one built from independent …

Dynamics of pions in ultrarelativistic heavy ion collisions
In an ultrarelativistic collision of heavy nuclei, such as 197Au, at an energy Vs above roughly 10 GeV per nucleon pair, nuclear transparency effects are expected to give rise to a baryon-poor central region. Matter in the central region can begin either as a pion fluid or as a quark-gluon plasma, …

Jet Quenching in Relativistic Heavy Ion Collisions at the LHC
Jet production in relativistic heavy ion collisions is studied using Pb+Pb collisions at a center of mass energy of 2.76 TeV per nucleon. The measurements reported here utilize data collected with the ATLAS detector at the LHC from the 2010 Pb ion run corresponding to a total integrated luminosity …

Multi-instrument studies of heavy ion solar energetic particle transport
… spacecraft is presented. The temporal variation and the dependence of heavy ion abundances on solar longitude were studied and quantitatively characterised during SEP events between 2006 and 2016. Ionic abundances vary over the duration of SEP events, e.g. Fe/O often shows a decrease over …
