Design and Characterization of a Low-Current Compact Extraction and Matching System for a High-Frequency RFQ in Medical Applications
Year: 2026
Type: article
Abstract: A low-current compact extraction and matching system has been designed and experimentally tested to evaluate its capability for direct proton injection of 15 keV into a 750 MHz radiofrequency quadrupole for medical applications. The design methodology combined 2D and 3D layouts, supported by detailed electrostatic simulations. First experimental results are reported, including beam current characterization and irradiation measurements under varying operating conditions. These results are benchmarked against simulation data to provide a preliminary evaluation of system performance. Ongoing efforts focus on extending the experimental campaign to consolidate these findings. A comparative study with a gridded-lens-based extraction and transport system is also being conducted to achieve reliable matching of high-quality beams to high-frequency RFQs for clinical implementation.
