Unit test instrument for Pol_FieldBox

Identification

• Site: Tests_polarization
• Author: Erik B Knudsen
• Origin: DTU Physics
• Date: Jan 20

Description

An instrument with a single field box with a 1 mT magnetic field along the y-axis.
A neutron beam polarized aling the x-axis is emitted with central wavelength such
that the  polarization is rotated pihalfturns radians in the field.
