The potential of FLASH radiotherapy is being clearly demonstrated in experiments and clinical trials have started for skin and intraoperative treatment using low-energy electrons. Generalizing FLASH therapy to treat large, deep-seated tumours requires new radiation delivery infrastructure. A collaboration between Lausanne University Hospital (CHUV), CERN and PMB/THERYQ is developing such a facility. The facility uses >100 MeV electrons and draws heavily on the accelerator technology developed by the CLIC linear collider project. The webinar will describe the major features and status of the project.

Focus on FLASH technology week
During the last week in March, Physics World focused on FLASH – bringing you updates on some of the latest research advances in the field and hosting two keynote webinars highlighting cutting-edge developments in FLASH technology. Our other FLASH webinar is also available to watch now:

• The PHASER platform: innovative designs to bring X-ray-based FLASH to the clinic

Walter Wuensch is a principle researcher at CERN currently leading the development of high-performance linac technology for multiple applications including the CLIC linear collider and a broad range of next-generation compact accelerators including XFELs, Inverse Compton Sources and medical linacs. The accelerator technology development is complemented by both theoretical and experimental investigations of the fundamental processes that occur at high gradients including field emission and breakdown. The investigations are illuminating long-standing mysteries and the newly gained understanding are being applied to a range of applications the electron linacs, RFQs and high-voltage systems.
