First multi-bend achromat lattice consideration

The first proposed lattice for a `diffraction-limited light source' is reported. This approach has now more or less been used for the MAX IV project.

Diffraction-limited storage-ring vacuum technology

A compact lattice and small magnet apertures will be the main characteristics of future diffraction-limited storage rings, adding difficulties for the design of the vacuum system of these machines. The use of NEG coatings and distributed absorbers could provide a solution to overcome these challenges.
