	6	Kiessig Thickness Calculator Tool
	7	=================================
	8
	9	Description
	10	-----------
	11
[5ed76f8]	12	This tool estimates real space dimensions from the position or spacing of
	13	features in recipricol space. In particular a particle of size $d$ will
	14	give rise to Bragg peaks with spacing $\Delta q$ according to the relation
	15
	16	.. math::
	17
	18	d = 2\pi / \Delta q
	19
	20	Similarly, the spacing between the peaks in Kiessig fringes in reflectometry
	21	data arise from layers of thickness $d$.

[a9dc4eb]	25	Using the tool
	26	--------------
[ec392464]	27
[5ed76f8]	28	To get a rough thickness or particle size, simply type the fringe or peak
[1e01486]	29	position (in units of 1/\|Ang\|\) and click on the Compute button.
