| Abstract | The Transfer Tunnel 20 (TT20) in the CERN North Area (NA) contains transfer lines TT21-25 to transport beam extracted from the Super Proton Synchrotron (SPS). The beam is shared between three primary production targets simultaneously using two sets of Lamberston septa magnets. Proposals for a future facility in the ECN3 underground cavern might require new optics in the TT20 transfer lines to provide high-intensity, `unsplit' beam directly to future NA experiment(s). Here, we present an optics to transmit an unsplit beam through the splitter magnets without collimation and through the transfer lines without losses. The T4 target is unsuitable for high beam intensity and a closed magnetic orbit bump is proposed to bypass the target. |
