    9 In yellow you see the fiducial positions of our [https://docs.astro.columbia.edu/wiki/SavinGroup/MergedBeams/FirstLeg#BPM Beam profile wire scanner], i.e. when the wire is going through the center of the beamline. The collector signal obtained when the wire actually crosses the beam is shown in blue.

    1110Transport of the beam is not bad at all. After some more changes of the setup (Steerers, slits, retractable cup, ...) we now have the first leg complete and get 14 micro Amps about where we'll put the spherical deflector.
    … …  
    2726After some changes to the installed beam optics, we now get the source to emit 16 micro Amps! The beam shape is reasonable and, most importantly, pretty well centered. The beam is oval, about 6mm full diameter in the vertical and 3.5mm diameter in the horizontal direction.
