Kiessig Thickness Calculator Tool
Description
This tool estimates real space dimensions from the position or spacing of features in recipricol space. In particular a particle of size $d$ will give rise to Bragg peaks with spacing $Delta q$ according to the relation
d = 2π ⁄ Δq
Similarly, the spacing between the peaks in Kiessig fringes in reflectometry data arise from layers of thickness $d$.
Using the tool
To get a rough thickness or particle size, simply type the fringe or peak position (in units of 1/|Ang|) and click on the Compute button.
