Constant magnetic field in a isosceles triangular coil
Identification
Site:
Author: Morten Sales, based on Pol_constBfield by Peter Christiansen
Origin: Helmholtz-Zentrum Berlin
Date: 2013
Description
Rectangular box with constant B field along y-axis (up) in a isosceles triangle.
There is a guide (or precession) field as well. It is along y in the entire rectangular box.
A neutron hitting outside the box opening or the box sides is absorbed.

The angle of the inclination of the triangular field boundary is given by the arctangent to xwidth/(0.5*zdepth)
This component does NOT take gravity into account.
Example: Pol_triafield(xwidth=0.1, yheight=0.1, zdepth=0.2, B=1e-3, Bguide=0.0)
