Third‐generation storage rings are massively evolving due to the very compact nature of the multi‐bend achromat (MBA) lattice which allows amazing decreases of the horizontal electron beam emittance, but leaves very little place for infrared (IR) extraction mirrors to be placed, thus prohibiting traditional IR beamlines. In order to circumvent this apparent restriction, an optimized optical layout directly integrated inside a SOLEIL synchrotron dipole chamber that delivers intense and almost aberration‐free beams in the near‐ to mid‐IR domain (1–30 µm) is proposed and analyzed, and which can be integrated into space‐restricted MBA rings. Since the optics and chamber are interdependent, the feasibility of this approach depends on a large part on the technical ability to assemble mechanically the optics inside the dipole chamber and control their resulting stability and thermo‐mechanical deformation. Acquiring this expertise should allow dipole chambers to provide almost aberration‐free IR synchrotron sources on current and `ultimate' MBA storage rings.
