Modeling and design of the ilc test area beam absorbers at fermilab

Detailed MARS 15 simulations have been performed on energy deposition and shielding of the proposed ILC Test Area absorbers. It is designed for up to 50 kW of 800- MeV electron beam power and provides unlimited occupancy conditions in the experimental hall. ANSYS analysis based on the calculated energy deposition maps confirms robustness of the proposed design of the absorbers and beam windows for normal operation and for various failure modes.
