Study of Energy Deposition and Activation for the LINAC4 Dump

This document provides estimates of energy deposition and activation for the dump of the future LINAC4 accelerator. Detailed maps of power density deposited in the dump are given, allowing to perform further thermo mechanical studies. Residual dose rates at a few cooling times for different irradiation scenarios have been calculated. Moreover, the air activation has been evaluated and doses to the reference population group and to a worker intervening in the cave at the shutdown have been predicted. Calculations were performed with the Monte Carlo particle transport and interaction code FLUKA.
