The FLUKA geometry of the TOTEM Roman Pot detector system at the LHC (Version 2012)

During the design phase of the TOTEM experiment, several Roman Pot detector models were simulated in FLUKA to address radiation damage and radiation protection issues as well as to define specific accidental scenarios involving beam losses in the Roman Pot components. These FLUKA models, often implemented “ad-hoc” for a given calculation and with the best knowledge of the detector at a given time, lack consistency and nowadays do not properly reflect all final detector components installed at the LHC. In this note, we describe a new FLUKA geometry built in the framework of the FLUKA accelerator generator and based on the most updated version of the integration model of the TOTEM Roman Pot detector.
