Figure 3
Dose distributions of the scattered photons outside the side wall (a) and the roof (b) of the optics hutches, calculated taking into consideration the linear-polarization effect. The slant length is considered to depend on both the azimuthal and the scattering angle to introduce the polarization effect. The side walls of the BL47XU and BL02B1 beamlines stand parallel to the beam path and perpendicular to the photon polarization vector, and parallel to the photon polarization vector for the BL45XU beamline. The roof walls of the BL47XU and BL02B1 beamlines are parallel to the plane expanded by the beam path and polarization vector, and perpendicular for the BL45XU beamline.
