Abstract

The successful physics program of the LHC Run-1 data taking period has put a strong emphasis on design studies for future upgrades of the existing LHC detectors. In ATLAS, testing alternative layouts through the full simulation and reconstruction chain is a work-intensive program, which can only be carried out for a few concept layouts.To facilitate layout prototyping, a novel technique based on the ATLAS reconstruction geometry and a fast simulation engine have been established that allow fast layout iterations and a realistic but fast Monte Carlo simulation. This approach is extended by a fast digitisation and reconstruction module.

Highlights

  • With the first long shotdown (LS1) ending and Run-2 of the LHC data taking starting, the LHC experiments shift part of their focus to detector upgrade

  • The TrkDetElementBase is the base class for all tracking detector elements with methods for reading out all relevant information, extended by the geometry description implemented in GeoModel

  • A new technique for building custom tracking geometry has been developed reading the detector description from XML configuration files removing any dependence on GeoModel libraries
