Two In-vacuum Undulator Mobile Carriages (2 m long) and one REVOLVER undulator mobile carriage (2.3 m long)

In-vacuum Undulator mobile carriage is a mechanical support of permanent magnet arrays with vertical motion for opening and closing the Gap between the girders. Additional motions consist in global displacement of the vertical position of the carriage called Offset, and others secondary motions used for tuning the Tapper and the Pitch positions of the carriage. The typical size for this carriage is 2 m x 2.3 m x 1.4 m with an estimated weight of 3 Tons. REVOLVER undulator mobile carriage: Mechanical support of permanent magnet arrays with vertical motion for opening or closing the gap between the girders and the capability of rotation of the upper and lower girders around their axis of symmetry (by 90°). Four motors are therefore required to power the revolver. Two motors are used to vary the gap and the taper, and two other motors are used to rotate independently the upper and lower girders. The typical size of such a mechanical structure is 2.3 m x 2 m x 1.2.m with an estimated weight of 4.5 Tons.
