Plasma lenses, formed by gas discharges along the beam axis of charged particle beams, offer a compact and efficient method for magnetic focusing. Initiated between ring electrodes, these discharges generate high currents that produce azimuthal magnetic fields, enabling symmetric focusing in both transverse planes as described by Ampère's law. Compared to traditional solenoids and quadrupoles, plasma lenses can achieve stronger magnetic field gradients, making them promising for compact accelerator applications. This work presents the design, construction, and experimental evaluation of a plasma lens at the LIGHT beam line at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt. The study specifically investigates its effectiveness in collimating ion beams generated via Target Normal Sheath Acceleration (TNSA), highlighting its potential as an alternative beam transport solution.
