The Source_div component

Neutron source with Gaussian divergence

Identification

• Author: KL
• Origin: McStas release
• Date: November 20, 1998
• Version: 1.4

Description

The routine is a rectangular neutron source, which has a gaussian
divergent output in the forward direction.
The neutron energy is uniformly distrubuted between E0-dE and E0+dE.

ToDo: More flexible specification of E distribution.

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
width	m	Width of source
height	m	Height of source
hdiv	deg	FWHM of horizontal divergence
vdiv	deg	FWHM of vertical divergence
E0	meV	Mean energy of neutrons.
dE	meV	Energy spread of neutrons.

Output parameters

None.
