Angular-energy distributions of neutrons emitted from the Wendelstein stellarator – Monte Carlo simulations

Abstract

Angular-energy distributions of neutron currents expected from the Wendelstein 7-X stellarator have been calculated by means of Monte Carlo methods using a simplified model of the stellarator. The MCNP5 code has been employed. The obtained spectra are to be used to design five sets of neutron and gamma detectors placed above this D-D fusion reactor. The counters are to provide information concerning both thermonuclear plasma diagnostics and dosimetry.
