Monte Carlo Simulations of the TCC2 radiation test facility at CERN

The hard radiation environment of the Large Hadron Collider (LHC) demands for a careful choice of COTS (Components Off The Shelf) and custom made electronics that will be installed in the tunnel. All the electronic equipment should be tested on their radiation tolerance. For this purpose we use dedicated radiation facilities and the TCC2 test facility at CERN, where there is a mixed radiation field similar to that of the LHC. To achieve optimum results on the electronics radiation tolerance it is essential to study thoroughly the complex radiation field in the test facility at CERN. For this purpose a detailed Monte Carlo simulation of the test area was carried out and the calculations were compared with the dosimetry measurements already available.
