Recent Studies of the Resonances at a Cell Tune of 0.25 Using the Ibex Paul Trap

We use the IBEX linear Paul trap to study the resonance at a cell tune of 14 with both equal and unequal transverse tunes, at a range on intensities. We compare this experimental result to simulation using the PIC code Warp. We find that the experimental result differs from the simulation, which may be explained by the ion loss in the IBEX experiment, which more closely replicates a real accelerator. Knowledge of the tune corresponding to greatest beam loss is important for the design of future high intensity machines.
