DART calculates the total number of displacements, primary knocked-on atoms, recoil spectra, displacement cross sections and displacement per atoms rates in a poly atomic solid target, composed of many different isotopes, using ENDF/B-VI derived cross sections.
To calculate these values, different incident particles were considered: neutrons, ions and electrons.
The user needs only to specify an incident particle energy spectrum and the composition of the target.
The number of displaced atoms are calculated within the Binary Collision Approximation framework. To calculate the number of displacements the DART code does not use the classical NRT dpa analytical formula, which is only appropriate for projectile and target of the same mass. It numerically solves the linearized Boltzmann equation for a polyatomic target.
It can be a useful tool to select the nature and energy of ions or electrons in particle accelerators or electron microscopes to mimic the primary damage induced by neutron irradiation in nuclear plants or fission facilities.
Typically any ENDFB format evaluation may be used. This package includes the ENDFB-VI nuclear data library.
