Description

CLEAR (CERN Linear Electron Accelerator for Research) is a versatile electron beam user facility operating at CERN, providing beams with energies up to 200 MeV across a broad range of bunch charges, emittances, and timing configurations.
The facility serves a diverse and growing internal and external user community, supporting a wide experimental program spanning multiple domains of accelerator research and applications.
In this paper, we present an overview of the current status of CLEAR, summarizing the breadth of experiments conducted across recent operational runs and the key developments of the facility.
We further report on the installation and commissioning of the second beam line, a new beamline branch featuring a dog-leg section, a set of slits in both dispersive and non-dispersive regions, and larger aperture focusing elements, which have the potential to significantly expand the facility's experimental capabilities and accessible beam parameter space.
The continued development of CLEAR's infrastructure and the steady growth of its user base consolidate its role as a unique and flexible platform for accelerator research and technology demonstration at CERN.
