Description

This note gives an overview of the Machine Detector Interface (MDI) design performed for the
Feasibility Study of the FCC-ee. A general overview of the FCC-ee interaction region (IR) is given in
Section 1, where the main requirements are discussed. The IR optics design, as far as the magnetic
configuration and compensation scheme is given in Section 2. The mechanical description of the FCC-
ee interaction region layout is discussed in Section 3, followed by the description of its mechanical
integration and alignment in Section 4. Section 5 describes the simulation framework of the machine
elements and the vertex detector. Finally, the effects of the machine induced backgrounds, which have
implications on the design and requirements on the electronics and detector technology, are discussed
in Sections 6 and 7.
