Description
he KAERI Heavy-ion Irradiation Facility (KAHIF) is a linear-accelerator-based infrastructure designed to emulate neutron-induced displacement damage in next-generation nuclear and fusion structural materials [1-3]. KAHIF consists of a 25.96 MHz Split-Coaxial Radio-Frequency Quadrupole (SC-RFQ) operating at 178 keV/u, and a 51.92 MHz Interdigital H-mode (IH) drift tube linac capable of accelerating heavy ions up to 1.09 MeV/u. In 2025, KAHIF achieved a critical operational milestone by successfully establishing a high-flux solid metal ion beam [4-6]. By optimizing a Metal Ions from Volatile Compounds (MIVOC) system using ferrocene at room temperature, the facility stably extracted and accelerated an Fe13+ ion beam to 9.68 MeV.
This paper outlines the operational performance of KAHIF faciliy for high-dose irradiation. To further advance extreme material testing capabilities, 2026 strategic upgrades include rebuilding the Medium Energy Beam Transport (MEBT) line for precise beam diagnostics, installing a 950°C ultra-high-temperature target chamber, and developing a He/Fe simultaneous dual-beam irradiation architecture.
