Resonant cavity for quadrupole moment measurements of heavy ion beams
Year: 2026
Type: conference-paper
Abstract: Non-invasive and fast beam emittance measurement is highly demanded for accelerated multi-charge-states heavy ion beams. The driver linac of the Facility for Rare Isotope Beams is the first accelerator intended to accelerate multiple charge states of stripped heavy ion beams and deliver up to 400 kW to the isotope production target. Emittance measurements of, for example, five charge states of uranium beam using conventional wire profile monitors take more than an hour in one location and add up to a few hours throughout the linac. This work presents design studies for a resonant cavity monitor capable of instantaneous measurement of the quadrupole moment of the beam distribution. Coupling with the beam and signal acquisition system, the separation between monopole, dipole, and quadrupole modes of the cavity are discussed.
