Description

The 100 MeV proton linac at KOMAC has operated since 2013, providing irradiation services for materials, biomedical, semiconductor, and nuclear/basic science through four user beamlines. The accelerator comprises a 50 keV injector, 3 MeV RFQ, and DTL to 100 MeV. Major beamlines support multidisciplinary research, semiconductor radiation assessment, and isotope production, while a white-spectrum neutron service is in pilot operation with official user service planned for 2026. A Beam Test Stand supports accelerator R&D, including machine-learning-based tuning, emittance control, and advanced phase-space diagnostics. A 200 MeV upgrade based on a normal-conducting SDTL is in preparation. The LINAC’26 conference provides an opportunity to present the operational status, beamline utilization, and progress toward the 200 MeV upgrade.
