    • Strictly speaking, the emittance of a crystalline beam is finite because of quantum effects. The possible lowest limit of projected emittances should be around ℏ/mc where ℏ is the Planck constant and c is the speed of light.

    • The only exception is a one-dimensionally ordered coasting beam (string crystalline beam) in which all particles are aligned along the design beam orbit.

    • note
    • As first discussed in Ref. [9] and theoretically formulated in Ref. [24], a longitudinal tapered force simultaneously cools the transverse dimension, provided that the cooling section has finite dispersion. Therefore, this type of frictional force is useful not only for beam crystallization but also for general 3D cooling of a charged-particle beam.

    • The spatial configurations of Coulomb crystals in an ordinary ion trap are similar to "bunched" crystalline beams rather than "coasting" crystalline beams.

    • note
    • Since the tapered force cannot directly cool the vertical betatron motion, we have added weak transverse dissipation in these simulations. Similarly, the crystalline beams in Figs. 1 and 3 have been obtained with a combination of the ideal tapered force and transverse linear friction.

    • Only when the beam is initially well conditioned, we observe some "sympathetic" transverse cooling due to Coulomb collisions.
