Technical Data

Primary beam
 
  • Neutron guide NL-1; supermirror m = 2
  • Monochromator:
    PG(002)
    mosaicity: 0.4 – 0.5°
  • Higher order filter:
    Astrium type velocity selector
    transmission 87% for 2.4 Å
  • Wavelength range:
    2.4 - 5.6 Å with selector
    2.4 - 6.1 Å without selector
  • Collimation by adjustable slits down to Ø = 1 mm
 

Beam properties at the sample position
 
  • Wavelength resolution at sample position:
    ∆λ/λ = 2.9 % at 2.4 Å
  • Beam divergence (no slits)
    0.8° FWHM horizontal
    0.7° FWHM vertical
 

Main detector
