Description
PARticle Therapy REsearch Center (PARTREC) operates the AGOR AVF superconducting cyclotron capable of delivering multiple particle types (protons, light and heavy ions) at multiple extraction energies (from 8 to 190 MeV/u, dependent on particle type).
Following decades of routine operation of AGOR’s cryogenic system, the filling of the cryostat and extraction channels with liquid helium became increasingly unstable. This greatly impeded AGOR’s ability to reliably deliver ion beams and eventually resulted in a prolonged technical shutdown of the facility. A comprehensive cryogenic system overhaul has further enhanced operational stability. The many lessons learned during this exercise will be presented.
Recent upgrades have significantly expanded PARTREC’s capabilities. The new EMC1 extraction element has demonstrated reliable operation. High-intensity beam development (>1 μA) now supports both FLASH radiotherapy and the production of theranostic radioisotopes, notably Terbium. Dedicated dosimetry monitors have been developed to ensure precise dose delivery at ultra-high dose rates. Advancements in ion source technology now allow fine control of proton beam intensity and the inclusion of xenon in the heavy ion cocktail, contributing to more efficient radiation hardness testing. These developments position PARTREC as a unique multidisciplinary hub for cutting-edge research in particle therapy, radiobiology, and nuclear science.
