The CMS/TOTEM nominal FLUKA Model; version 1.0.0.0

For a physics experiment such as CMS the understanding of the radiation environment is of great interest. It is necessary for the evaluation of the detector performance, effectiveness of shielding or to assess radiation damage. Monte Carlo simulations have been performed for CMS with various simulation tools. FLUKA is one of these tools used to understand the particle rates inside CMS and in the whole experimental cavern. It is not realistic to implement every detail of the actual detector in a FLUKA geometry. However, there is the need to have a geometry which reflects the layout of the real detector by using the correct material composition and the correct mass. The work presented here builds on an existing FLUKA model describing the CMS geometry. It includes modifications of the Preshower detector, CASTOR, the pixel detector and BCM2. TOTEM T1 and T2 were also implemented. Between 2010 and 2011 the LHC ran with a beam energy of 3.5\,TeV, while during 2012 a 4.0\,TeV beam energy was used. For this reason simulations using 3.5\,TeV and 4.0\,TeV as proton energy have been performed and will be presented as an example application of this geometry.
