Description

Simple instrument model serving as an example and unit tyest of the He3-cell model.
For the values POLHE=.8 and .5 results comply with "Batz, M et al. “(3) He Spin Filter for Neutrons.”
Journal of research of the National Institute of Standards and Technology vol. 110,3 293-8. 1 Jun. 2005, doi:10.6028/jres.110.042"

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
pol		If "x","y", or "z" set polarization along that axis. If "0" use a zero polarization.	"y"
lamb_1	AA	Lower wavelength limit to simulate	1
lamb_2	AA	Upper wavelegnth limit to simulate	10
RANDOM		Randomize polarization vector in the (ideal) polariser	0
polval		Set polarization to (polval,polval,polval). Gets overridden by pol	1
POLHE		Polarization of the 3He-gas in the cell.	0.7
