Very preliminary integration issue: Position of the power couplers
Preferred to initial model if we have many waveguide between the two tunnels

Couplers from above would be accessible
Waveguide network would block access to couplers from below (+ probes, controls,water cooling pipes, etc…)Would need a larger tunnel to access from the other side of the modules (Compatibility with cryoline?)

Summary◊ SPL would have a 1.7% slope ◊ 550m should be considered as a maximum length
(including debuncher and vertical bend to PS2)◊ A warm magnet option just fits in the footprint◊ Surface buildings and main shafts can be located
around the mid-point of the SPL◊ It would be a big advantage to install the power
couplers from above
