=== Particle Definition
The particle mass and charge are defined by:
The beam particle is defined by `PARTICLE` attribute, which includes a
direct assignment of the particle mass and charge, as indicated below.
For other type of particle beams, this attribute must not be used.
Instead, the particle beam is defined by means of the `MASS` and
`CHARGE` attributes specified by the user.
