DAN-SANS :: KWS-3 :: Standard Mode :: Data Reduction Introduction



In this introduction everybody could process raw-data obtained at KWS-3 SANS instrument both virtually (looking to more than 100 pages of step-by-step introduction) as well practically at own computer (raw-data is attached also).

  • Info-Table was generated to get information about raw-data located in the data-folder
  • Three sample in the example were measured in two instrument configurations: 9.2m and 1.2m
  • Standard mask-matrix “mask” is used for sensitivity matrix “sens”, for absolute calibration and for beam center calculation
  • For every instrument configuration two masks are created: for radial averaging (masked direct beam) and for transmission calculation (only direct beam place is not masked)
  • Table of configurations was filled step-by-step.
  • Script Table was automatically generated
  • Transmission was calculated for every configuration using the direct beam method (we measured without beam-stop)
  • Radial Averaging and merging with the standard mask are shown
  • Matrixes of the detector images were calculated (fully corrected): scattering signal was not ISOTROPIC
  • Radial Averaging and merging with the “vertical” and “horizontal” masks are shown
  • Data, measured at 1.2m were normalised to the ratio of transmissions measured at 1.2m and 9.2m
