The Capillary Component

A capillary tube

Identification

Description

A Capillary tube allowing for reflections along the tube. A material coating can be applied. Multilayer
coatings may be handled by generating a reflectivity file (e.g. by IMD) and setting rtable=1.
Waviness is implemented using the model described in
Wang et.al., J. Appl. Phys., 1996
where the grazing incidence angle $\theta$ is altered as
$\theta' = \theta + \delta \theta \in [-min(theta,\Delta\theta,\Delta\theta]$
This ensures that reflected rays will never be scattered into the capillary.
\Delta\theta is the value specified by the parameter waviness.

Input parameters

Parameters in boldface are required; the others are optional.
NameUnitDescriptionDefault
coatingName of file containing the material data (i.e. f1 and f2) for the coating"Be.txt"
longw If non-zero, waviness is purely longitudinal in its nature.1
radiusmRadius of the capillary.1
lengthmLength of the capillary.0.2
R0 Fixed constant reflectivity0
rtable if nonzero, the coating file contains an E,theta paramterized matrix of raw reflectivities.0
wavinessradThe momentaneous waviness is uniformly distributed in the range [-waviness,waviness].0
