abstract = {{A novel scheme for laser sculpting a neutralised hydrogen beam from a parent beam of hydrogen ions circulating in a racetrack accelerator was proposed at IPAC19*. Such a method was shown in simulation to produce a particle beam with reduced transverse emittance, based on a simple static laser sculptor geometry. This paper investigates effects of translating or raster scanning a focussed laser-sculptor transversely within the hydrogen ion beam, which creates new possibilities for non-invasive beam diagnostics of the transverse phase space. The optimisation of the optical geometry, intensity and the temporal characteristics of the laser beam are investigated for laser-induced extraction of neutralised beamlets, from which the beam profile and emittance can be reconstructed. Photo-detachment simulations are performed in a photon-particle interaction framework that has been implemented in BDSIM, a Geant4 based particle tracking code**. We evaluate the design of a potential experimental demonstration at a hydrogen ion linac, the Front End Test Stand, at Rutherford Appleton Laboratory, UK.}},
