Description
Since 2013, the 100 MeV proton linac at the Korea Multi-purpose Accelerator Complex (KOMAC) has been in continuous, stable operation, providing reliable irradiation services for materials, biomedical, semiconductor, and nuclear sciences across four dedicated user beamlines. To expand user capabilities, a white-spectrum neutron beam service is undergoing pilot operation, with official service scheduled to launch in 2026. Additionally, a dedicated Beam Test Stand is being utilized for advanced accelerator R&D, focusing on machine-learning-based beam tuning, emittance control, and phase-space diagnostics. Concurrently, technical preparations are well underway for a 200 MeV energy upgrade utilizing a normal-conducting Separate-type Drift Tube Linac (SDTL) structure. This presentation reports on the recent operational achievements, beamline utilization stauts, and the core R&D progress toward the 200 MeV expansion project at KOMAC.
