MERIX is a medium energy resolution 4 circle diffractometer for non-resonant and resonant inelastic x-ray measurements.
- Spot size: focused horizontal x vertical = 45 um x 10 um, unfocused = 2.2 mm x 0.4 mm
- Momentum resolution varies with incident energy but the angular acceptance of the analyzer is 5.7 degrees. This can be reduced with slits.
- chi range is -100 to -80
- Strip detector scan columns:
| E |
Energy |
| C |
Number of counts, unnormalized in any way |
| A |
number of strips used at each energy |
| F |
C*max(A)/A |
| X |
error bar for F column = max(A)*sqrt(C/A) |
| M |
beam monitor |
| N |
max(M)*C/M |
