AB - The Front End Test Stand (FETS) is an R&D project at Rutherford Appleton Laboratory (RAL) with the aim to demonstrate a high power (60 mA, 3 MeV with 50 pps and 10 % duty cycle), fast chopped H-ion beam. The diagnostics of high power particle beams is difficult, due to the power deposition on diagnostics elements introduced in the beam, so non-invasive instrumentation is highly desirable. The laser wire emittance scanner under construction is based on a photo-detachment process, utilizing the neutralized particles produced in the interaction between Laser and H-beam for beam diagnostics purposes. The principle is appropriate to determine the transversal beam density distribution, as well as the transversal and longitudinal beam emittance behind the RFQ. The instrument will be located at the end of the MEBT with the detachment taking place inside a dipole field. Extensive particle tracking simulations have been performed for various settings of the MEBT quadrupoles to investigate the best placement and size of the 2D scintillating detector, and to determine the range and resolution of the instrument. Additionally the power distribution in the following beam dumps has been determined.
