  16. Upgrade strategy from 500 GeV to 3 TeV • 500 GeV phase 500 GeV sectors with CLIC 502 structure at 80 MV/m (50 GeV/sect) with return loop and dumps positions at the optimum position for 3TeV Extra sector installed in space of BDS future extension at 3 TeV • Two upgrade alternatives from 500 GeV to 3 TeV: • CLIC G structures at 100 MV/m all along linac • Remove last sector to provide space for BDS and reuse components to build one of the additional sector • Adapt quadrupole focusing of the last 4 sectors from low to high En and change accelerating structures from 502 to G on the last 4 sectors • Install 20 additional sectors in each linac with G structures at 100 MV/m (62.5 MeV/sector) • CLIC G at 100 MV/m except for last 4 sectors with 502 at 80 MV/m • Remove last sector to provide space for BDS and reuse components to build one of the additional sector • Adapt quadrupole focusing of the last 4 sectors from low to high En but maintain 502 accelerating structures at 80 MV/m (50 MeV/sect) • Install 21 additional sectors in each linac (4*50MeV+21*61.9MeV) • 1 additional sector and total tunnel length increased by 868 m
