Franz Peters, Georg Gassner WPM/HLS Status and June 17 th, Reminder Undulator Length = 132 Meter plus… 33 U-Segments need to be stable in a line within a few microns X & Y- Motion of single U - Segments could be larger, eventually… Vertical U-Position = f (Support temperature) = ~ 15 Micron/ºC Unpredictable motions may occur by several reasons, as … Undulator Length = 132 Meter plus… 33 U-Segments need to be stable in a line within a few microns X & Y- Motion of single U - Segments could be larger, eventually… Vertical U-Position = f (Support temperature) = ~ 15 Micron/ºC Unpredictable motions may occur by several reasons, as …

Franz Peters, Georg Gassner WPM/HLS Status and June 17 th, WPM = Wire Position Monitor HLS = Hydro Leveling System Conductive wire is stretched (140 m) inside a conductive tube (8 mm) RF Signal (CW) is transmitted along this air isolated “coaxial cable” RF loops inside the tube. Loop currents determines the wire position Conductive wire is stretched (140 m) inside a conductive tube (8 mm) RF Signal (CW) is transmitted along this air isolated “coaxial cable” RF loops inside the tube. Loop currents determines the wire position Pipe ½ filled with water. Water surface used as common reference Capacitive sensors measure the distances to this common reference Ultrasonic sensor detects distance of surface to under water plains Pipe ½ filled with water.
