Abstract:

The NuMI Facility was intended to be flexibly changed between 3 energies of beams, LE, ME, and HE.
However, the changeover requires extensive downtime to move and realign horns and the target. We
propose to implement a
flexible arrangement where the target can be remotely moved in the beamline direction
to change the beam energy and the horns remain fixed. In addition to having the attractive feature
of keeping the horn optics fixed, the motion of the target can be performed more quickly and hence on
a more frequent basis. We discuss potential increases in statistics in the high energy
region, systematic cross-checks available, and the improved beam monitoring capabilities with such
variable energy beams.
