A Monte Carlo method for detectors using the Total Energy Deposition principle (which is obtained via application of the PHWT) was proposed. In this method, both dead-time and pile-up effects are considered simultaneously in a consistent manner. To validate this method in harsh count rate conditions, we have applied it to two different types of CD liquid scintillators at different count rate conditions and demonstrated the capability to account for these effects in neutron-capture cross-section measurements at the CERN n_TOF facility. The method brings very good results under the count rates up to 8 c/s.
