Cornell Group Achieves Milestone in Superconducting Cavity Test


The International Linear Collider (ILC) is a proposed electron-positron collider with the highest energies ever achieved in such an accelerator. The design has two 12 Km (7 miles) linear accelerators facing each other with collisions occurring in the center between them. In order to achieve the desired energy of 250 GeV (250 billion electron volts) in each beam, superconducting accelerating cavities must provide a sufficient energy "kick". In early June, the Cornell SRF group successfully processed and tested the first US ILC cavity. The cavity is now ready for the final stage of cleaning, called electropolishing, and is on track to achieve the ILC goal of 35 MV/m (MegaVolts per meter). See full press release from ILC.
