Abstract

ABSTRACT A novel compact extraction system has been developed at CERN to optimize high-current linacs for medical and industrial use. Replacing the traditional LEBT with a 2 cm-long electrode-based design, it enables efficient proton extraction and acceleration to 45 keV. Tested at the Linac4 test stand, both experimental and simulation results confirm its ability to match to the RFQ acceptance with improved beam quality and reduced footprint, offering a viable solution for next-generation compact linacs.
