| 11 | This tool is to approximately estimate the thickness of a layer |
|---|
| 12 | or the diameter of particles from the Kiessig fringe in |
|---|
| 13 | SANS/NR data, and uses the Kiessig relation; |
|---|
| 14 | thickness = 2*Pi/fringe_width. |

| 21 | To get a rough thickness or particle size, just type the Kiessig fringe width (in the 1/A unit) |
|---|
| 22 | and click on the 'Compute' button. Then the output value will be show up in the 'Thickness' text box.</p> |
