Results of optimization energy deposition and radiological studies performed for the LBNF hadron absorber system are presented. The model of the LBNF complex starting from the beam extraction from the Main Injector and primary beam line through the pion-production target, focusing horns, target chase, decay channel, hadron absorber system with its beam instrumentation and civil infrastructure – all with corresponding radiation shielding – was developed using the ROOT-based geometry option in the MARS15 code. Both normal operation and accidental conditions were studied for the 120-GeV proton beam at 2.4 MW. Various design options were considered, in particular: (i) the absorber mask material and shape; (ii) the beam spoiler material and size; (iii) sculpted core aluminum blocks; (iv) various configurations of the core and its shielding and (v) numerous modifications of the overall system configurations. These helped find the optimal design solution for the absorber lifetime and radiation levels in the service building and environment to be within the design goals with an adequate safety margin.
