Welcome to CLEAR

the CERN Linear Electron Accelerator for Research.

The primary focus for CLEAR is general accelerator R&D and component studies for existing and possible future machines at CERN, based on a broad internal and external user community. The program covers two of the top priorities identified by the European Strategy for Particle Physics, namely the prototyping and validation of accelerator components for the upgrade of the Large Hadron Collider and its injector chain, and studies of high-gradient acceleration methods. The latter cover X-band studies for linear accelerators and also novel concepts as plasma and THz acceleration. CLEAR also provides unique training possibilities, as well as irradiation test capability, of which is worth mentioning a collaboration with the European Space Agency (ESA).
