Multi-Element Silicon Detectors

Powder Diffraction and X-Ray Scattering

Diffraction

  • Strip-shaped pixels form a 1-D position sensing detector with energy resolution 350eV
  • 320 strips on 0.125mm pitch -> 40mm total length and twelve 32-channel ASICs
  • Strips 8mm long

 

Diffraction

  • Sample-detector distance = 263mm
  • -> 8.7 degrees coverage, 0.03 degrees / strip
  • 13 measurements spaced 7.5 degrees apart, each 1 second count time
  • Total 20 second scan
