The extremely low emittance promised by multi-bend achromat (MBA) based lattices can be achieved only by strong focusing and combined functions magnets that are challenging the present technology for those magnets. Such a level of focusing can be achievable only if significantly small gap magnets are used. Such a requirement imposes extremely small vacuum chamber cross-section with very small vacuum conductance. A new vacuum strategy using distributed pumping and other challenging solutions are adopted to achieve the goals. This talk describes these challenges and presents a review of the technological solutions presently pursued.
