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
