Description

A stack of conical shells is simulated. Parabolic version.
To intersect the Wolter I plates we take advatage of the azimuthal symmetry and only consider the radial component
of the photon's wavevector.

Example: Ring_p( pore_th=0, ring_nr=3, Z0=FL, yheight=0.605e-3, mirror_reflec="mirror_coating_unity.txt", R_d=0, size_file="ref_design_breaks.txt")

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
ring_nr
pore_th
Z0	m	Distance between optics centre plane and focal spot (essentially focal length).
yheight	m	Height of the pore.
chamferwidth	m	Width of side walls.	0
gap	m	Gap between the plate and the intersection plane with the hyperbolic section.	0
zdepth			0
mirror_reflec		Data file containing reflectivities of the reflector surface (TOP).	""
bottom_reflec		Data file containing reflectivities of the bottom surface (BOTTOM).	""
size_file			""
R_d		Default reflectivity value to use if no reflectivity file is given. Useful f.i. is one surface is reflecting and the others absorbing.	1
waviness	rad	Waviness of the pore reflecting surface. The slope error is assumed to be uniformly distributed in the interval [-waviness:waviness].	0
longw		If non-zero, waviness is 1D and along the pore axis.	0
