The Soller_trans component

Soller collimator with rectangular opening and specified length.

Identification

• Author: KN
• Origin: McStas 1.0 (1998)
• Date: August 1998
• Version: 1.0

Description

Soller collimator with rectangular opening and specified length. 
The transmission function is an average and does not utilize knowledge of the
actual neutron trajectory.
A zero divergence disables collimation (then the component works as a double slit).
Added is an additional parameter ´transmission´ to take into account the
transmission probability. See Soller component.

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
xmin	m	Lower x bound on slits
xmax	m	Upper x bound on slits
ymin	m	Lower y bound on slits
ymax	m	Upper y bound on slits
len	m	Distance between slits
divergence	minutes of arc	Divergence angle (calculated as atan(d/len), where d is the blade spacing)
transmission	1	0<=transmission<=1)

Output parameters

Name	Unit	Description	Default
slope
