12 Advance Data and Power Management Systems (ADPMS) Housing 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 05-Nov-06 GEANT4 Space and Spenvis Users Worshop 2006 – Session II F.
