Experimental observation of the motion of ions in a resonantly driven plasma wakefield accelerator
Physical Review Letters American Physical Society 134:15 (2025) 155001
Abstract:
We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. The effect appears within a single wakefield event and manifests itself as a bunch tail, occurring only when sufficient motion of ions suppresses wakefields. Wakefields are driven resonantly by multiple bunches, and simulation results indicate that the ponderomotive force causes the motion of ions. In this case, the effect is also expected to depend on the amplitude of the wakefields, experimentally confirmed through variations in the drive bunch charge.High-level environmental sustainability guidelines for large accelerator facilities
