The Pol_constBfield Component

Constant magnetic field.

Identification

• Site:
• Author: Peter Christiansen
• Origin: RISOE
• Date: July 2006

Description

Rectangular box with constant B field along y-axis (up). The
component can be rotated to make either a guide field or a spin
flipper. A neutron hitting outside the box opening or the box sides
is absorbed.

Example: Pol_constBfield(xwidth=0.1, yheight=0.1, length=0.2, fliplambda=5.0)

Input parameters

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
xwidth	m	Width of opening
yheight	m	Height of opening
length	m	Length of field
B	Gauss	Magnetic field along y-direction	0
fliplambda		lambda for calculating B field	0
flipangle		Angle flipped for lambda = fliplambda fliplambda and flipangle overrides B so a neutron with s= (1, 0, 0) and v = (0, 0, v(fliplambda)) will have s =(cos(flipangle), sin(flipangle), 0) after the section.	180
