Date: Feb. 2016
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”)
Parameters in boldface are required; the others are optional.

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. |
