The MM_h Component

Date: Feb. 2017 Version: 1.1 Release: McXtrace 1.2 Origin: DTU Physics, DTU Space Single Pore as part of the Silicon Pore Optics (SPO) as envisioned for the ATHENA+ space telescope.

Identification

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.
NameUnitDescriptionDefault
pore_thmThickness of the pore walls (plates)
ring_nr1Ring number; selects the data block read from size_file
Z0mDistance between intersection plane and the focal spot (essentially focal length).
pore_heightmHeight of the pore. (Hence the inner radii are radius_{m,h}-pore_height)
pore_widthmWidth of a single pore
chamfer_widthmWidth of side walls.0
gapmGap between intersection with parabolic section and actual plate.0
zdepthmCurrently not used by the component0
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_filestrTable file with the per-ring geometry, read with block number ring_nr""
non_specular_filestrData file describing non-specular reflectivity""
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
