5. For instance, it is necessary to precool the beam with another cooling device, such that the beam density becomes high enough for the sympathetic coupling.

8. Needless to say, the beam is not necessarily bunched for 2D cooling in the transverse phase space. In order to extend a horizontal (vertical) cooling force to the vertical (horizontal) direction, only the first condition in Eq. (1) is required

13. If we wish to make a stable 3D crystalline beam, we eventually need the so-called "tapered" force; see, e.g., H. Okamoto and J. Wei, Phys. Rev. E 58, 3817 (1998).

15. The vertical oscillation is driven by the vertical dispersion induced through the solenoid coupling.
