Beschreibung
Plasma lenses, created by gas discharges along the beam axis of charged particle beams, provide a compact and efficient approach to magnetic focusing. High currents initiated between ring electrodes generate azimuthal magnetic fields via Ampère's law, enabling symmetric focusing in both transverse planes. Compared to conventional solenoids and quadrupoles, plasma lenses achieve substantially stronger field gradients in minimal space, rendering them highly attractive for compact accelerator applications.
This work presents the design, construction, and initial experimental investigation of such a plasma lens at the LIGHT beamline of the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt. The study specifically evaluates its capability to collimate ion beams from Target Normal Sheath Acceleration (TNSA), demonstrating the potential of plasma lenses as an alternative beam transport solution.
