Abstract

A resonance between the periodic focusing force and the envelope oscillations or the particle orbits can lead to beam halo formation and a dramatic decrease in brightness. A theoretical model has been developed for this parametric transport instability. The authors also investigated the instability on the Experimental Test Accelerator II (ETA-II). The instability can be excited by altering the excitation of just one solenoid.
