Guide_wavy Component
Models a rectangular guide tube centered on the Z axis. The entrance lies
in the X-Y plane.
For details on the geometry calculation see the description in the McStas
reference manual.
%BUGS
This component does not work with gravitation on. Use component Guide_gravity then.
Example values: m=2 Qc=0.0218 (nat. Ni) W=1/300 alpha=4.38 R0=0.995
