Figure 2
Total beamline transmission between the gas monitor detector placed behind the undulators in the beam-distribution area (BDA) and the CAMP interaction region. Solid curves are calculated values for both options of transport-mirrors. Colored symbols show measured transmissions at different photon energies using two 3 mm-diameter apertures in front of all the beamline optics, to prevent geometrical beam transmission loss in the transport and focusing mirrors. (Individual errors are smaller then the symbol size.) |
