    keyword=Beam back, slow raster check. Dilution runs

    Got beam back soonner than MCC initially expected.
    We did a quick check of slow raster at 2 cm. The 3rd rate increased a lot. But the slow raster pattern seems ok. Possibly indicating that the beam is scraping upsteam of the target (not at the target).
    We keep the slow raster to 1.8 cm for now. Will revisit the issue
    tomorrow after beam study.
    Started dilution runs.
