【 摘 要 】

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.
