Large dynamic range small-angle diffractometer D22

Small-angle scattering is a technique that measures the deviation to small angles (much less than one degree to several degrees) of an X-ray or neutron beam due to structures of small size in the sample. “Small” means dimensions of a few tenths to about 100 nanometres, such as clusters in alloys, polymers, or biological macromolecules.

New on D22

 

  • Polarisation and polarisation analysis are available on D22. (18-Jun-2007)
  • D22 has been equipped with additional security system during the 2004/2005 winter shutdown. The interlock system now requires pushing a button in the controlled area after checking the absence of any person before opening the beam. (04-Mar-2005)
  • Instructions in case of problems with the detector high voltage (i.e. no detector image or no detector movement possible) and with missing parts of the detector image (27-Jul-2004)
  • A new fast detector has been installed on D22 during the 2003/2004 winter shutdown. It is made up of 128 linear sensitive Reuter-Stokes tubes of 8 mm diameter with 15 bars of 3He. Each tube can count neutrons at a rate of 50 kHz with 10% dead time losses. (16-Mar-2004)
