The Pol_constBfield Component

Constant magnetic field.

Identification

• Author: Peter Christiansen
• Origin: RISOE
• Date: July 2006
• Version: 1.3

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	-	Width of opening (m).
yheight	-	Height of opening (m).
length	-	Length of field (m).
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

Output parameters

Name	Unit	Description	Default
