Low energy 750 keV LANSCE proton beam transport line before injection into Drift Tube Linac (DTL) has a length of 10 m and uses 22 quadrupoles, 6 steering magnets, 2 bending magnets, combination of prebuncher and main buncher, beam deflector, and collimators. Matching of the beam with the structure includes providing beam waists at the entrance of RF cavities, and matched beam Twiss parameters at the entrance to DTL. Typical beam emittance growth was at the level of 2-2.5. Beam based steering procedure was implemented to minimize emittance growth in the beamline. It includes determination of beam offset and beam angle entering group of quadrupoles and subsequent correction of beam angle to minimize beam offset in quadrupoles. Implementation of the procedure resulted in significant reduction of emittance growth at the level of 10%.
