Beamline Layout

The beamline schematic draw is shown in Figure 1 and the key parameters of the beamline are listed in table 1. The beamline provides high energy X-ray in the range from 30 to 162 keV. As shown in figure 1, the beamline employs a supper conducting wiggler as the light source to provide enough flux in the high energy range. After the front end, two optical hutches and two experimental hutches (LVP1 and ENG1) are inside the main building, while one optical hutch and two experimental hutches (LVP2 and ENG2) are built in the external building. A set of permanent low energy filters is located closest to the front end, followed by a white beam slit, which is used for the downstream beam definition. After the slit, a series of movable middle energy filters is employed in front of the cryogenically cooled meridional bending double Laue monochromator (DLM).

After ENG1, the beam is guided to the third optical hutch in the external building via a long transfer pipe by crossing the perimeter of the main experimental hall. The third optical hutch contains a dual white/monochromatic beam slit followed by a water-cooled sagittal bending double Laue monochromator. Next are the last two experimental hutches LVP2 and ENG2. All the experimental hutches can be operated in monochromatic mode as well as white beam mode.
