Description
Active plasma lenses are promising technologies for the focusing of high brightness electron beams due to
their radially symmetric focusing and their high field gradients (up to several kT/m). However, in a number
of experimental situations, the transverse non-uniformity of the current density flowing in the lens causes beam
emittance growth and increases the minimum achievable spot size. To study the physics of the capillary discharge
processes employed as active plasma lenses, we developed a 2-D hydrodynamic computational model. Here,
we present preliminary simulation results and we compare the computed magnetic field profile with one from
literature, which has been experimentally inferred. The result of the comparison is discussed.
