The Guide_tapering Component

Identification

Description

Models a rectangular guide tube centered on the Z axis. The entrance lies
in the X-Y plane.
The guide may be tapered.

 Example1:Guide_tapering(w1=0.1, h1=0.18, linw=0.1, loutw=0.1, 
 linh=0.1, louth=0.1, l=1.5, option="elliptical", R0=0.99, 
 Qcx=0.021, Qcy=0.021, alphax=6.07, alphay=6.07, W=0.003, 
 mx=1, my=1, segno=800)
 
 Example2:Guide_tapering(w1=0, h1=0, linw=0, loutw=0, 
 linh=0, louth=0, l=1.5, option="file=ownfunction.txt", R0=0.99, 
 Qcx=0.021, Qcy=0.021, alphax=6.07, alphay=6.07, W=0.003, 
 mx=1, my=1)

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
option 0
segno 1 number of segments (z-axis) for cutting the tube 800
w1 m Width at the guide entry 0
h1 m Height at the guide entry left and right horizontal mirrors left and right horizontal mirrors 0
l m length of guide  
linw 0
loutw 0
linh m distance of 1st focal point and real guide entry - top and bottom vertical mirrors 0
louth m distance of real guide exit and 2nd focal point - top and bottom vertical mirrors options are: "elliptical" - define elliptical function of guide walls "parabolical" - define parabolical function of guide walls "file=[filename]" - read in ASC-file with arbitrary definition for the curve of the guide walls 0
R0 1 Low-angle reflectivity 0.99
Qcx AA-1 Critical scattering vector for left and right vertical mirrors in each channel 0.021
Qcy AA-1 Critical scattering vector for top and bottom mirrors 0.021
alphax AA Slope of reflectivity for left and right vertical mirrors in each channel 6.07
alphay AA Slope of reflectivity for top and bottom mirrors 6.07
W AA-1 Width of supermirror cut-off for all mirrors 0.003
mx 1 m-value of material for left and right vertical mirrors in each channel. Zero means completely absorbing. 1
my 1 m-value of material for top and bottom mirrors. Zero means completely absorbing. 1
