Description
The EuPRAXIA Advanced Photon Source (EuAPS) will be the first user-oriented radiation source based on betatron radiation, and it is currently under development at Laboratori Nazionali di Frascati - INFN at the FLAME laser facility.
Betatron radiation is emitted due to the betatron oscillations of electrons in a plasma during the Laser WakeField Acceleration (LWFA) process. An intense laser beam (10$^{19}$ W/cm$^2$) is focused on a supersonic gas jet, simultaneously creating a plasma, injecting, and accelerating electrons, which then emit radiation.
A precise characterization of the plasma density, as well as the electron and radiation spectra, is required to optimize the source. Preliminary measurements of these parameters have been conducted using a Mach-Zehnder interferometer, a magnetic dipole and a CCD-X camera.
