Research on medical applications of particle physics is coordinated by Prof. Dr. Saverio Braccini and is centred on the medical cyclotron in operation at the Bern University Hospital (Inselspital). This accelerator provides 18-MeV proton beams of variable intensity (from a few picoAmpere to 150 microAmpere). It is equipped with a Beam Transfer Line (BTL) with independent access to the beam area for multidisciplinary scientific developments, and a Solid Target Station (STS) with automatic transfer of the target. The facility is conceived to perform industrial routine production of radio-pharmaceuticals and academic research in parallel.
Our group pursues several research lines based on particle accelerators and detectors for medical applications. We establish state-of-the-art methods for the production of radioisotopes for diagnostics and therapy (theranostics), in particular using solid targets. For an optimised radioisotope production, an accurate knowledge of the beam energy and of the cross section is crucial. Innovative methods are developed to assess these quantities and to improve nuclear data. We develop novel beam monitoring detectors to enhance the capabilities of our facility.
The cyclotron is used as a facility for radiation hardness studies for high-energy physics and space missions. We also perform studies on fundamental physics, radiation protection and particle therapy.
