A {\mu}-TPC detector for the characterization of low energy neutron fields

open access: yes, 2012
The AMANDE facility produces monoenergetic neutron fields from 2 keV to 20 MeV for metrological purposes. To be considered as a reference facility, fluence and energy distributions of neutron fields have to be determined by primary measurement standards.

A fast Monte Carlo code for proton transport in radiation therapy based on MCNPX

open access: yesJournal of Medical Physics, 2014
An important requirement for proton therapy is a software for dose calculation. Monte Carlo is the most accurate method for dose calculation, but it is very slow. In this work, a method is developed to improve the speed of dose calculation. The method is

Cold Crystal Reflector Filter Concept [PDF]

open access: yes, 2014
In this paper the theoretical concept of a cold crystal reflector filter will be presented. The aim of this concept is to balance the shortcoming of the traditional cold polycrystalline reflector filter, which lies in the significant reduction of the ...

MCNPX Simulations for Neutron Cross Section Measurements

open access: yes, 2010
This thesis presents MCNPX simulations of the SCANDAL set-up used at the Theodor Svedberg Laboratory for neutron scattering cross-section measurements. The thesis describes processes and data important for the upcoming off-line data analysis. In the experiment, neutrons scattered off the target are converted to protons which are stopped in scintillator
