2. MPE, Garching – Jan. 28, 2014Italian contribution to WFI: L. Piro Athena, the Advanced Telescope for High Energy Astrophysics 2 The rationale The primary Italian contribution to mission elements is XIFU Other smaller contributions include participation to mirror and Ground Segment activities. This approach has been consistently presented to ASI and properly ackwnoledged by the agency Credible approach for WFI contributions: limited and harmonized with present commitments on XIFU. For WFI we propose activities that are carried out by the Italian consortium on XIFU and that can be – with a reasonable delta effort – developed for WFI
