Abstract :
In order to provide reproducible conditions, a steering feedback system consisting of two beam position monitors and two steering magnets is installed in the beam line immediately upstream of the injection point into CELSIUS. Moreover, a 1 mm aluminium wire placed vertically on the horizontally moving stripping foil mechanism measures the beam profile and the emittance. This allows adjusting upstream quadruples to optimise injection conditions. Preliminary operational result is presented
