Description
The CERN Linear Accelerator for Research (CLEAR) is composed of a versatile 200 MeV electron linac followed by a 20 m experimental beamline, and is operated as a multi-purpose user facility at CERN. Running in parallel with the main CERN accelerator complex, but completely independent from it, CLEAR started operation in 2017 and has been providing electron beams to a large and varied range of experiments. The goal of CLEAR is to provide to users high-quality electron beams with flexible and rapidly-tunable parameters, coupled with high availability and easy access to the experimental area. The main areas of research and application include beam instrumentation R&D and prototyping, novel accelerating techniques, irradiation of equipment for radiation hardness studies and the exploration of the potential use of electron beams for radiotherapy (VHEE/FLASH). CLEAR also plays a strategic role in CERN by maintaining expertise for electron linacs linked to future collider studies and as a training infrastructure for the next generation of accelerator scientists and engineers. In this talk we will provide an outline of the facility and its operation mode, and give highlights of its past and present experimental programme, with particular attention to activities done in collaboration with the John Adams Institute for Accelerator Science.
