| Two views of a sample in position for data-taking, as seen through the "upstream" camera (left) and the video microscope (right). The reticle lines show the nominal extent of the beam. The actual beam edges extend somewhat farther, so these areas should be kept clear of foreign material (glue, clay, wax, etc.). The sample material must be held in place in the beam -- if it is loose in the capillary, it will move when we spin the capillary (we spin at about 5400 r.p.m.).
