Description
For the future experiments at linear electron--positron colliders (ILC
or CLIC), detailed physics and detector optimisation studies are taking
place in the CLICdp, ILD, and SiD groups. The physics performance of
different detector geometries and technologies has to be estimated
realistically. These assessments require sophisticated and flexible full
detector simulation and reconstruction software. At the heart of the
linear collider detectors lies the particle flow reconstruction
requiring the combination of fine-grained calorimeters and advanced
clustering software.
The similarities between the different detector concepts allow for the
use of common software tools. All the concepts share an event data and
persistency format which enables the sharing of files and applications
across the concepts. Particle flow clustering, vertexing and flavour
tagging is already provided by stand alone packages via lightweight
interfaces. In the near future the geometry information for all detector
layouts will be provided by a unique source for the simulation and
reconstruction programs, providing further re-use of software between
the collaborations. In addition a track reconstruction package is
currently under development.
The sharing and development of flexible software tools not only saves
precious time and resources. Using common tools for different detectors
also helps to uncover bugs or inefficiencies that would be harder to
spot without multiple users. The concept of generic software tools and
some of the programs themselves can be beneficial to experiments beyond
the linear collider community.
