Abstract

Powerful flexible computer codes are essential for the design and optimisation of accelerator and experiments. We briefly review what already exists and what is needed in terms of accelerator codes. For the FCC-ee it will be important to include the effects of beamstrahlung and beam-beam interaction as well as machine imperfections and sources of beam induced backgrounds relevant for the experiments and consider the possibility of beam-polarisation. The experiment software Key4hep, which aims to provide a common software stack for future experiments, is described and the possibility of extending this concept to machine codes is discussed. We analyse how to interface and connect the accelerator and experiment codes in an efficient and flexible way for optimisation of the FCC-ee interaction region design, and discuss the possibility of using shared data formats as an interface.
