Si(111) monochromator and 27 mm period undulator.
Energy range 2.05- 20.7 keV (core range 5 -15 keV).
Can be used from 7 -20 keV in Si(333) mode with less flux but higher resolution.
Mechanical KB mirrors with Si and Rh stripes.
Mirrors can be moved from beam path for bulk EXAFS.
Down to 2 -5 (V) x 2 – 5(H) μm spot size.
Motorised sample stages
Movement range - 30 mm(X), 60 mm(Y)
| Detector | Specifications |
| Excalibur XRD detector | 16 MEDIPIX3 chips read-out at 100 frames per second in continuous mode or 1000 frames per second in burst mode - if burst mode is required, you must speak with beamline staff prior to proposal submission. A total detection area of the 3-module EXCALIBUR detector is 115 mm × 100 mm with a small 6.8 mm wide inactive region between modules at a very high spatial resolution small pixel size of 55 microns. |
| Two 4 element 1mm thick sensor Vortex Si Drifts detector with cube pre-amps | Xspress 3 electronics, 1kHz count rate per element in XAFS mode, potentially up to 2kHz - consult scientists if required. |
| Ionisation cahmbers | Transmission measurements (He, N2, Ar, Kr gases) |
Showing the smaple area in the I18 beamline with schematic and lable displaying two main modes of detection - Transmission(It) and fluorescence(If). For XRD, the excalibur detector is typically in the postion of the It ion chamber.
