v3 v4 4 4 //Calvin Dyson: // for the collaboration 5 5 6 == Technical==6 == Abstract == 7 7 8 8 Laser-driven ion sources offer potential advantages in a range of disciplines, including radiotherapy, but the beams created have a large divergence, creating significant challenges for conventional technologies that often rely on asymmetric focusing and require strong magnetic fields. The Laser-hybrid Accelerator for Radiobiological Applications (LhARA) proposes the use of a Gabor lens as a symmetric focusing system to capture the laser-driven beam. A Gabor lens uses the electrostatic field of a confined electron plasma to focus positively charged particles. The focusing strength is determined by the electron density and length. … … 13 13 Together, these results represent progress towards a stable, sufficiently dense plasma, marking crucial steps in the development of a Gabor lens for the capture and transport of laser-driven ion beams. 14 14 15 == Programme Summary==15 == Summary for display in the program == 16 16 Laser-driven ion beams have significant potential for future applications in radiobiology and particle therapy, but their large divergence makes efficient capture and transport challenging. A Gabor lens offers a symmetric focusing solution using the electric field of a confined electron plasma. This contribution presents experimental progress at Swansea University in generating and stabilising the plasma required for such a lens, including improvements achieved using oscillating electric fields and a dimple potential. Complementary WarpX simulations support the development of a practical focusing system for applications such as LhARA. 17 17
