Description
Achieving plasma-based accelerators for users demands careful control not only of the beam energy and energy spread, but also of transverse beam properties such as emittance, size, and divergence. Since plasma-based accelerators typically produce beams with significantly larger energy spread and emittance than conventional RF accelerators, several questions remain to be addressed, particularly, the transverse beam dynamics. In this article, it is presented an analytical description of the transverse beam properties evolution in a constant-focusing channel representing a plasma density plateau assuming a finite energy spread. The resulting expressions provide qualitative and quantitative guide to understand the transverse beam dynamics under these conditions.
