From ILC newsline: “Extending the energy reach of the ILC”

“The GDE design for the ILC as presented in the Reference Design Report (RDR) is for an electron-positron colliding beam facility having a maximum centre-of-mass energy of 500 gigaelectronvolts (GeV). No design or upgrade path to 1 teraelectronvolt (TeV) was presented in the RDR. However, the option to upgrade to higher energies was explicitly maintained in the reference design by ensuring that the beam delivery system could be upgraded, beam dumps were sufficient for higher energy and other considerations. Now, having had significant success achieving high gradients for the baseline machine and anticipating results that will guide the choice of energy from the LHC, we are undertaking a study of paths towards higher energy for the Technical Design Report (TDR) and are considering an R&D focus towards cost-effectively reaching higher energy for the post-TDR programme.
