Figure 1
Key components along the X-ray path before the sample position (40 m from the X-ray source IU24). From upstream, there are millisecond shutters (MS shutter) and the first set of X-ray beam position and intensity monitors (XBPM) called Rigi, sitting on the granite chopper stage (to accommodate a future chopper system for time-resolved measurements). These are followed by an attenuator, the first set of JJ slits/pinholes (JJ-SP1), the second set of XBPM (Civi) and the second set of JJ slits/pinholes (JJ-SP2) sitting on the collimation granite stage. A motorized PIN diode (5 mm-diameter active area), situated 1 mm after the S₃N₄ vacuum exit window, can be moved into the beam path for centering the JJ-SPs.
