The ESRF lattice designed in the late 1980s is a 32 double bend achromat lattice with 32 cells designed with triple quadrupoles on both sides of the insertion device (ID) segments. Several years ago, a new setting of the quadrupole (linear lattice) was implemented with no current in the quadrupole adjacent to the insertion devices. The advantage of this is a longer length available for IDs. Such an advantage is now entering into effect with the Upgrade Programme. As the beamlines are being refurbished, new IDs are being designed and built which make use of the 6 m length available for undulator magnets. Since December 2010, ID18 and ID30 have been extended from 5 to 6 m with a 6 m long narrow aperture (8 mm) fixed gap NEG coated ID chamber. Further transitions that involve significant vacuum work are planned during each long shutdown (summer and winter) with no disruption to the user programme.
