Halo Formation and Chaos in RMS-Matched Beams Propagating Through a Periodic Solenoidal Focusing Channel

The dynamics of continuous space-charge-dominated beams propagating through a periodic solenoidal focusing channel is studied using a test-particle model. It is shown that nonlinearities in the self fields induce chaotic particle motion and beam halo formation for beams that are root-means-squared (rms) matched into the focusing channel but have nonuniform… CONTINUE READING
