abstract = {The present fixed-gap undulator system for FLASH1 and the
new FLASH2 undulators will share the same electron beam
accelerator, thus 12 variable gap undulators are needed in
order to provide radiation of different wavelengths to both
experimental halls independently. Each of the 12 devices has
a length of 2.5m. The magnet structure with a period length
of 31.4mm provides a maximum field of 0.96T with an
effective K-parameter of 2.81 at minimum gap. Phase,
vertical and horizontal trajectories have been tuned based
on Hall probe and stretched wire measurements. Remaining
multipoles were optimized with moderate gap dependence by
using magic fingers. At some magnet structures, shims were
placed to correct gap dependent field integrals. All
undulators have an rms vertical and horizontal trajectory
flatness},
