Figure 5
Measurements, taken at 67 keV (left) and 81 keV (right), of vertical beam profiles at 35 m (immediately after the CRL) and ∼60 m from the source, made to ascertain the vertical angular collimation achieved by the CRLs from 29 rad to a few microradians. All plotted profiles are measured ones, except for the solid lines in the two lower 35 m panels, which are calculated (square symbols are used for measurements here). |
