Description

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

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
ring_nr
radius_m	m	Ring radius of the upper (reflecting) plate of the shell at the optic centre.
Z0	m	Distance between optics centre plane and focal spot (essentially focal length).
xwidth
yheight	m	Height of the shell.
gap	m	Gap between the plate and the intersection plane with the hyperbolic section. (currently ignored)	0
chamferwidth	m	Width of side walls.	0
length			0
mirror_reflec		Data file containing reflectivities of the reflector surface (TOP).	""
bottom_reflec		Data file containing reflectivities of the bottom surface (BOTTOM).	""
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
primary		If non-zero, the shell is considered a primary reflector, and extends towards negative z. I.e. the entry plane is behind the z=0-plane. If zero, the shell is considered secondary	1
dalpha	deg	Offset to the alpha angle computed from the focal length. Useful for targeting the modified conical geometry (currently ignored).	0
waviness	rad	Waviness of the shell 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 shell axis.	0
