Figure 1
(a) Rowland geometry experimental setup. A diagrammatic representation of the Rowland circle geometry is shown. The photon source (s), detector (d) and spherically bent analyser crystal (a) are positioned on a circle with a radius equal to half the bending radius (R) of the analyser crystal. The Bragg angle (θB) is defined between the source and the analyser and can be adjusted by moving the analyser and detector along the Rowland circle while keeping the source fixed. Each of the three or 14 analyser crystals, along with their corresponding positions on the detector, is arranged on a separate Rowland circle that intersects at the common source point. (b) Schematic of the experimental setup, showing the new 14-analyser spectrometer of the I20-Scanning beamline at Diamond Light Source. The X-rays produced by the wiggler are first vertically collimated, then monochromated using a sophisticated four-bounce monochromator, ensuring high spectral purity. Subsequently, precision focusing mirrors are employed to achieve optimal horizontal and vertical beam focusing, enhancing spatial resolution and intensity for high-resolution experiments. |
