Description
EuPRAXIA@SPARC_LAB is a FEL user-facility currently under construction at INFN-LNF in the framework of the EuPRAXIA collaboration. The electron beam will be accelerated to 1 GeV by an X-band linac followed by a plasma wakefield acceleration stage. This high-brightness linac requires diagnostic devices able to measure the beam parameters with high accuracy and resolution. To monitor the beam energy and its spread, magnetic dipoles and quadrupoles will be installed along the linac, in combination with scintillating screens and CCD cameras. Macroparticle beam dynamics simulations have been performed to determine the energy measurement setup which provides the best compromise in terms of accuracy and resolution. Similar diagnostics evaluations were carried out for the spectrometer installed at the 100 MeV RF linac of the radioactive beam facility SSRIP, located at IFIN-HH (Romania) and whose commissioning phase is foreseen for 2026. Optics measurements have been performed to characterize the resolution and field of view of the optics system foreseen to be used for beam energy monitoring at EuPRAXIA@SPARC_LAB and SSRIP.
