Description

A single pore is simulated, which may have thick walls. The top and bottom are curved cylindrically
azimuthally, and according to the Wolter I optic lengthwise (sagitally). This is the hyperbolic part.
The azimuthal curvature is defined by the radius parameters.

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: MM_h( pore_th=0, ring_nr=1, Z0=12, pore_width=0.83e-3, pore_height=0.605e-3, chamfer_width=0.17e-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
pore_th
ring_nr
Z0	m	Distance between intersection plane and the focal spot (essentially focal length).
pore_height	m	Height of the pore. (Hence the inner radii are radius_{m,h}-pore_height)
pore_width
chamfer_width			0
gap	m	Gap between intersection with parabolic section and actual plate.	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).	""
side_reflec		Data file containing reflectivities of the side walls (LEFT and RIGHT).	""
size_file			""
non_specular_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			0
longw			0
