Computer Center RP requires a shielding of 6.9m of earth to keep Bld 513 a non designated area sets the altitude of Linac4 A. Kosmicki & M. Poehler
n_TOFtarget area 160µSr/h in Klystron gallerie for 7 1012 ppp on n_TOFtarget (20 GeV, 0.33Hz) A. Kosmicki & M. Poehler
TI2 injection line to LHC SPL tunnel or SPL to PS2 transfert line crosses TI2 fromabove A. Kosmicki & M. Poehler
Constraints on slope and length of the SPL Computer Center n_TOFtarget area Linac 4 SPL tunnel – slope = 1.7% TI2 injection line Transfert line to PS2 – slope = 8.4% ~550m
SPL "baseline" layout Cold continuous cryostat 5 Gev version (HP): 23 x β=1 modules + 2 de-modulator modules extraction regions to Isolde and Eurisol 10 x β=.65 modules length = 121 m SPL length = 527.38 m 4 Gev version (LP): 18 x β=1 modules + 2 de-modulator modules extraction regions to Isolde and Eurisol SPL length = 452.58 m T. Renaglia
Continuous cryostat and warm magnet options "Compact" version (gain on interconnections): 5 Gev version (HP):SPL length = 485.14 m (-42.24 m with respect to "baseline") "Warm quadrupole" version (withseparatecryoline): 5 Gev version (HP):SPL length = 535.92 m (+8.54 m with respect to "baseline")

Downstreamlimit of main service shaft Too far, assume 320m max. A. Kosmicki & M. Poehler
Verypreliminaryintegration issue: Position of the power couplers SPL Tunnel Machine & Tunnel Services JMB 03-07-2009 Preferred to initial model if we have manywaveguide between the two tunnels J-M. Bianco
Couplersfromabovewouldbe accessible • Waveguide network would block access to • couplersfrombelow (+ probes, controls, • water cooling pipes, etc…) • Wouldneed a larger tunnel to access • from the otherside of the modules • (Compatibility withcryoline?) J-M. Bianco
Summary • SPL would have a 1.7% slope • 550m shouldbeconsidered as a maximum length(includingdebuncher and vertical bend to PS2) • A warm magnet option justfits in the footprint • Surface buildings and main shaftscanbelocatedaround the mid-point of the SPL • It wouldbe a bigadvantage to install the power couplersfromabove
