A compact solution for ion beam therapy with laser accelerated protons

The recent advancements in the eld of laser-driven particle acceleration have made Laser driven Ion Beam Therapy (L-IBT) an attractive alternative to the conventional particle therapy facilities. To bring this emerging technology to clinical application we introduce the Broad Energy Assorted depth-Dose deposition (BEAD) scheme which makes ecient use of the large energy spread and high dose-per-pulse of Laser Accelerated Protons (LAP) and is capable of delivering homogeneous doses to tumors. Furthermore, as a key component of L-IBT solution we present a compact, iso-centric gantry design with 360° rotation capability with an Integrated Shot-to-shot Energy Selection System (ISESS), for efficient transport of LAP with large energy spread to the patient. We show that gantry size could be reduced by a factor of 2-3 compared to conventional gantry systems by utilizing pulsed, air-core magnets.
