T. Matsushita 1 Waveguide length with 3D model Internal waveguides The shortest = 1.5 m The longest = 2.6 m Others depending on the spacing Front face of solenoid to the active plane of the station = 400 mm Tracker length 1100 mm 400 mm

T. Matsushita 3 Wavelength with 3D model PP1 2 3 12 13 External waveguide length PP 1 - C-1 : 175 cm PP 2 - C+1 : 170 cm PP 3 - C-2 : 155 cm PP 4 - C+2 : 160 cm PP 5 - C-3 : 160 cm PP 6 - C+3 : 155 cm PP 7 - C-4 : 145 cm PP 8 - C+4 : 160 cm PP 9 - C-5 : 135 cm PP10 - C+5 : 125 cm PP11 - C-6 : 125 cm PP12 - C+6 : 125 cm PP13 - C-7 : 130 cm Patch-panel numbering Cryo-side numbering C+1C+8 C-1C-8 The shortest = 1.25 m The longest = 1.75 m

T. Matsushita 4 Wavelength with 3D model The shortest internal length + The longest external length = Total length 1.5 + 1.75 = 3.25 m The longest external length + The shortest external length = Total length 2.6 + 1.25 = 3.85 m But each station has five waveguides so … The longest internal one should match five shortest external one: => 2.6 + 1.3 = 3.9 m
