Figure 5
Top view of the experimental set-up at the SPring-8 BL29XUL beamline, hutch EH2. Abbreviations not in the text are as follows: FS = front 2 mm × 2 mm slit; I0 and I1 = ionization chambers; CC = Si 333 symmetric channel cut; PIN = PIN diode used to monitor the 220 Bragg reflection of the BBB; PW = lucite (Plexiglas) wedge; MS = motorized slit. If the CCD camera is moved out, the dashed line to its left shows the beam path to the APD. The BBB assembly shown in Figs. 2 and 3 is here shown only schematically for simplicity. |
