The Powder1 Component

General powder sample with a single scattering vector.

Identification

Description

General powder sample with a single scattering vector.
The shape of the sample may be a cylinder of given radius or a box with dimensions 
xwidth, yheight, zthick.
The area to scatter to is a disk of angular radius 'd_phi0' situated at the target.
The target itself is either situated according to given coordinates (x,y,z), or
setting the relative target_index of the component to focus at (next is +1).
This target position will be set to its AT position. When targeting to centered
components, such as spheres or cylinders, define an Arm component where to focus at.

Example: Powder1(radius=0.015,h=0.05,q =1.8049,d_phi0 =0.07,pack=1,j=6,DW=1, 
      F2=56.8,Vc=85.0054,sigma_a=0.463,target_x=0,target_y=0, target_z=1000)
