The Pol_FieldBox Component

Magnetic field component.

Identification

• Author: Peter Willendrup, based on Pol_simpleBfield
• Origin: RISOE
• Date: August 2006
• Version: 1.1

Description

Rectangular box with a definable B field.

The component corresponds to a setup of two slits (in/outgoing) plus starting and ending Pol_simpleBfield instances. Easy to use 
solution for e.g. precession fields and flipper fields.

The current algorithm used for spin propagation is:
SimpleNumMagnetPrecession
in pol-lib.
and does not handle gravity.

GRAVITY: NO
POLARISATION: YES

Example: Pol_FieldBox(xw=0.1, yh=0.1, length=0.2, Bx=0, By=1, Bz=0)

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
xw	m	Width of opening.
yh	m	Height of opening.
length	m	Length of field.
Bx	T	Parameter used for x composant of field.
By	T	Parameter used for y composant of field.
