ID14 is an undulator beamline. The straight section is currently occupied by an in vaccum Cryogenically cooled Permanent Magnet Undulator (CPMU) with period 18 mm and a  "revolver" undulators with period 27 mm and 20 mm, respectively. The CPMU is 2 m long while the revolver undulator is 1.6 m long. The minium gap for the in vaccum CPMU is about 6 mm. The vacuum pipe crossing the revolver undulator is 10 mm high and thus allows a minimum gap of 11 mm between the two magnet arrays of the revolver undulator.

(I need to put correct values here)
