Conclusions Conclusions
• The Attenuation efficiency for several laminates of CFRP with wolfram layer was measured
• The validation of the Monte Carlo – GEANT4 model was successfully carried out.
• The Basis for future simulations was set up in the Computer Cluster at Kumpula
• The GEANT4 simulated proton transmission for the CFRP with wolfram layer and Aluminium both with the same areal mass indicates that saving mass could be achieved
