McStas: He3_spin_filter Instrument at Test

[ Identification | Description | Input parameters | Output parameters | Links ]

The He3_spin_filter Instrument

Test instrument for He3_cell


  • Site: Test
  • Author: Pietro Tozzi and Erik B Knudsen
  • Origin: DTU Physics et.
  • Date: Nov 20
  • Version:(Unknown)


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
