Abstract: Top up is increasingly becoming a standard mode of operation for synchrotron light sources. Although it brings a very stable source in terms of intensity and position, the regular injections potentially perturb the beam. In order to investigate the perturbation of the beam from the imperfections of the injection kickers (i.e. non-closure of the bump), we use an X-ray pinhole camera equipped with a fast CMOS-sensor giving a rate of up to 3200 frames per second to monitor the image of the beam. The analysis of the observed beam size as well as position allows quantifying the perturbation from the kickers that can be seen on beamlines. In addition we compare the observed motion to bunch-by-bunch position data recorded in both vertical and horizontal planes, which reveals to be very complementary.
