AB - The Rutherford Appleton Laboratory (RAL) is developing a front end suitable for High Power Proton Applications HPPA. The main components are an H <sup>-</sup> ion source with up to 60 mA current at 65 keV, a transport section to match the beam to an RFQ with 3 MeV output energy and a LEBT comprising a chopper system with several buncher cavities. Photo detachment can be used as a non-destructive diagnostics method. The paper reports on progress with a beam profile monitor that is placed in a pumping vessel right after the ion source at the intersection to the Low Energy Beam Transport (LEBT). This diagnostics tool consists of mirrors inside the vacuum to scan the laser beam through the beam, the actual detector to measure photo detached electrons, laser and optics outside the vacuum and electronics to amplify and read out the signal. The paper summarizes the experimental set-up and status, discusses problems and presents recent measurements.
