McStas: Pol_simpleBfield_stop

[ Identification | Description | Input parameters | Links ]

The Pol_simpleBfield_stop Component

Magnetic field component.

Identification

  • Site:
  • Author: Peter Christiansen and Peter Willendrup
  • Origin: RISOE
  • Date: August 2006

Description

End of magnetic field region defined by a previous Pol_simpleBfield component.

The component is concentric. It means that it requires a

// START MAGNETIC FIELD
COMPONENT msf =
Pol_simpleBfield(xw=0.08, yh=0.08, length=0.2, Bx=0, By=-0.678332e-4, Bz=0)
AT (0, 0, 0) RELATIVE armMSF

// HERE CAN BE OTHER COMPONENTS INSIDE THE MAGNETIC FIELD

// STOP MAGNETIC FIELD
COMPONENT msfCp = Pol_simpleBfield_stop(msf)
AT ("SOMEWHERE") RELATIVE armMSF

In between the two components the propagation routine
PROP_DT also handles the spin propagation.
The current algorithm used for spin propagation is:
SimpleNumMagnetPrecession
in pol-lib.
and does not handle gravity.

GRAVITY: NO
POLARISATION: YES

Example: Pol_simpleBfield_stop(Pol_simpleBfield_stop)
