LASER-HYBRID ACCELERATOR FOR RADIOBIOLOGICAL APPLICATIONS
Abstract
Background and Aims
The Laser-Hybrid Accelerator for Radiobiological Applications (LhARA) programme aims to reduce the costs associated with hadron radiotherapy by replacing a conventional accelerator with a laser-source capable of producing protons and ions and a Gabor lense for capturing before acceleration. This approach will allow the response of ultra high dose rates and tightly focused beams to be studied both in vivo and in vitro.
Methods
LhARA will use a high intensity laser as the ion source, which will be captured by a novel gabor lense before further acceleration. Phase one of LhARA will allow in-vitro radiobiological experiments with 15 MeV protons. Phase two will use an FFA to accelerate the beam up to 127 MeV protons for in-vivo and in-vitro experiments. In addition, ions will be studied in phase two up to 34 MeV/u.
Results
Initial funding for Phase one has been secured through the UK Research and Innovations Infrastructure Fund for the Ion Therapy Research Facility (ITRF) in the UK which will allow the LhARA programme to investigate the laser-source, the Gabor lense, shot-by-shot dosimetry using ion-acoustic imaging, novel end-stations and beam monitoring, as well as facility integration.
Conclusions
We will present the current LhARA concept as well as the outline of the initial two year design phase of the programme and the role of LhARA within ITRF, culminating in the LhARA Conceptual Design Report in 2024.
