4. 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
