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.

ring_nr |
1 |
Ring number; selects the data block read from size_file |
|
|
pore_th |
m |
Thickness of the pore walls (plates) |
|
|
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. |

|
mirror_reflec |
|
Data file containing reflectivities of the reflector surface (TOP). |
”” |
|
bottom_reflec |
|
Data file containing reflectivities of the bottom surface (BOTTOM). |
”” |
|
size_file |
str |
Table file with the per-ring geometry, read with block number ring_nr |
”” |
|
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. |
