We analyze effects of the Higher Order Modes (HOM) heating in the FCC ee Interaction Region (IR). Interacting beams excite electromagnetic waves in the complicated geometry of the beam chamber. We discuss a possibility to design a chamber with a minimum RF impedance and suggest using HOM absorbers in the IR to capture the main part of the excited electromagnetic waves.
