Description
CERN’s Transfer Tunnel 20 (TT20) connects the Super Proton Synchrotron (SPS) to three primary targets in the North Area which provide secondary particles to experiments further downstream. Two splitter collimators (TCSC) are installed along this line, each protecting their respective downstream Lambertson septum magnets, which distribute the slow-extracted 400 GeV/c proton beams among the targets. During Long Shutdown 3 (LS3, 2026–2029), two redesigned TCSCs will be installed to improve cooling efficiency, mechanical robustness, and maintainability in the context of the North Area Consolidation (NA CONS) project. The new design also incorporates additional radiation shielding to reduce dose rates in the surrounding area and minimise personnel exposure during tunnel interventions. This contribution presents the main design improvements, thermo-mechanical analyses, and manufacturing developments implemented to enhance the reliability, radiation safety, and thermal performance of the TT20 splitter collimators.
