  2. 1. Development of New Monte Carlo Methods in Reactor Physics : Criticality, Non-Linear Steady-State and Burnup Problems

    Author : Jan Dufek; Jan Wallenius; Waclaw Gudowski; Cheikh Diop; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; reactor physics; fission source; inactive cycles; convergence; burnup; steady-state; criticality; eigenvalue; Nuclear physics; Kärnfysik;

    Abstract : The Monte Carlo method is, practically, the only approach capable of giving detail insight into complex neutron transport problems. In reactor physics, the method has been used mainly for determining the keff in criticality calculations. READ MORE

  4. 2. Monte Carlo particle transport codes for ion beam therapy treatment planning : Validation, development and applications

    Author : Till Tobias Böhlen; Irena Gudowska; Oliver Jäkel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; ion beam therapy; treatment planning; cancer therapy; microdosimetry; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : External radiotherapy with proton and ion beams needs accurate tools for the dosimetric characterization of treatment fields. Monte Carlo (MC) particle transport codes, such as FLUKA and GEANT4, can be a valuable method to increase accuracy of dose calculations and to support various aspects of ion beam therapy (IBT), such as treatment planning and monitoring.
