MagneticFieldReader

Magnetic field loading for a detector

Status	Functional
Maintainers	Paul Schuetze (paul.schuetze@desy.de)

Description

Unique module, adds a magnetic field to the full volume, including the active sensors. By default, the magnetic field is turned off.

The magnetic field reader only provides constant magnetic fields, read in as a three-dimensional vector. The magnetic field is forwarded to the GeometryManager, enabling the magnetic field for the particle propagation via Geant4, as well as to all detectors for enabling a Lorentz drift during the charge propagation.

Parameters

model : Type of the magnetic field model, currently only constant possible.
magnetic_field : Vector describing the magnetic field.

Usage

An example is given below

[MagneticFieldReader]
model = "constant"
magnetic_field = 500mT 3.8T 0T
