Abstract
Intense uncoupled beams are conventionally transported through periodic focusing lattices composed of linear optical elements that provide radial confinement against defocusing space-charge forces. In such systems, interplane coupling has traditionally been regarded as an undesirable perturbation. Recently, however, the concept of matched transport in periodic quadrupole focusing channels has been extended from uncoupled beams to those exhibiting significant correlations between the two transverse degrees of freedom [C. Xiao et al., Periodic four-dimensional solution for transport of intense and coupled coasting beams through quadrupole channels, Phys. Rev. Accel. Beams 27, 031602 (2024)]. Building on this development, the present work generalizes the full four-dimensional rms-moment matching formalism to periodic solenoid transport channels. A notable application of this approach, for instance, is the efficient transport of high-current, low-energy proton coasting beams.
