Abstract:
A "four-bump" set of magnets is proposed for the Fermilab Switchyard to control relative intensity between the Meson and Neutrino-Muon beamlines. Control currently relies on moving the electrostatic septa that split the beam, which can add to setup time and complications when experiments request frequent intensity changes. Furthermore, movement of the septa can increase beam loss on the downstream Lambertson magnet. By magnetically bumping the beam to change the split ratio, consistent alignment of the beam shadow and Lambertson septum can be achieved over the desired intensity range.
