A pulsed laser is transported through fibres and focused into the 160 MeV H⁻ beam. Its interaction with the H⁻ ions detaches electrons that are collected by an electron-multiplier, while the resultingH⁰ particles, after being separated from the main H⁻ beam by a dipole magnet, are recorded by a diamond strip detector, few meters away from the interaction point. The emittance and profile are reconstructed from the laser step by step scan of the beam. After several years of feasibility tests and prototyping, this paper will present all details about the final HW and SW implementation and the 2022 experimental results.
