Figure 1
Beamline layout showing the KB pair, where VFM focuses vertically onto the entrance slit (Sin) and HFM horizontally onto the exit slit (Sout), the vertically dispersing VLS PGM constituted by a plane mirror PM, two VLS plane gratings G (only shown in the top view) and an elliptical refocusing mirror VRFM. The PGM can work at constant magnification while Sin and Sout are kept fixed. The deflection angle is 2.4° for VFM, HFM and VRFM. |
