Calculation of intervention doses for the CNGS facility
The purpose of the CNGS (CERN Neutrinos to Gran Sasso) project is to generate at CERN a powerful artificial muon-neutrino beam aimed at the Gran Sasso Laboratory in Italy. There, detectors will detect those neutrinos and try to disentangle those, which on their 730 km trip have changed their flavour...

description | The purpose of the CNGS (CERN Neutrinos to Gran Sasso) project is to generate at CERN a powerful artificial muon-neutrino beam aimed at the Gran Sasso Laboratory in Italy. There, detectors will detect those neutrinos and try to disentangle those, which on their 730 km trip have changed their flavour. During the operating lifetime of the neutrino beam facility some interventions are required. These maintenance operations have to be planned in advance to define the guidelines of design and operational procedures in order to keep the doses received by personnel As Low As Reasonably Achievable (ALARA-principle). A calculational method developed for the Monte Carlo simulation program FLUKA has been used, which allows one to compute dose equivalent rates from induced radioactivity for different cooling times in the regions of the human intervention. In this paper the method of calculation is described, the results of dose equivalent rate in the areas of interventions are summarized and discussed and finally, these results are applied to estimate doses received by personnel during interventions. |
