The Thermal Scattering Law Project

Harnessing modern methods for material modeling and high-fidelity thermal scattering evaluations, the Scattering Law Project provides access to nuclear thermal scattering data from fundamental inputs to benchmark testing on key reactor and nuclear criticality materials to inspire and support the next generation of nuclear applications.

Paraffin Wax

Paraffin is a soft solid colorless material composed mainly of multicomponent n-alkanes, which are hydrocarbons with the general formula CnH2n+2.Paraffin wax was modelled in LAMMPS using a slow cooling rate to allow the hydrocarbons to align in crystalline form. Using this crystalline model, the velocity autocorrelation function (VACF) and corresponding density of states (DOS) were derived. These were then used in  FLASSH 1.0 to calculate the thermal scattering law (TSL) for paraffin wax as a crystalline material.
