 Using a Faraday Cup means that beam needs to stop on it. This means that checking beam from the ion source (BCMs are not accurate at low energies), you must stop beam delivery downstream. This can be useful as an addition layer of protection when you stop the beam with the chopper. Several of the Beam Inhibit Modes rely on specific FCs indicating IN to be satisfied. At higher energies, neutron production becomes an issue so the beam intensity must be reduced to use FCs further downstream in the Linac.  Using a Faraday Cup means that beam needs to stop on it.
