Figure 4
Beam current at the sample, IB, versus qm. The solid symbols represent measurements with the number of guides NG = 0 to NG = 9 for pinhole collimation with the NVS at λ = 6 Å (black circles), HOPG at λ = 4.75 Å (green triangles) and deflector (red squares). The open squares are the currents for two choices of slit width, 1.25 and 2.5 mm. The open circle is the current through 12 beams of the converging pinhole collimation.
