Description
EuPRAXIA is a leading European project aimed at the development of a dedicated, ground-breaking, ultra-compact accelerator research infrastructure based on novel plasma acceleration concepts. The INFN Laboratori Nazionali di Frascati will be equipped with an X-band LINAC followed by a plasma wakefield acceleration stage driving the first fifth-generation free electron laser (FEL) source driven by a plasma-based accelerator, the EuPRAXIA@SPARC_LAB facility [1]. The FEL will be characterized by a small footprint and will deliver ultra-bright photon pulses for experiments in the water window (3-5 nm) to the user community [2]. In addition, the possibility of building a second photon beamline with seeded FEL pulses in the range between 50 and 180 nm [3] and of exploiting the X-ray betatron radiation emitted by the electrons accelerated in plasma [4] are being explored.
We present an overview of the foreseen applications of these photon sources, which include imaging and spectroscopic studies on a variety of biological and inorganic materials, giving information on their structure and dynamical behavior.
