Science ministry says proton accelerator reaches 40,000 hours of cumulative operation

A 100-megaelectronvolt-class linear proton accelerator operated by the Korea Atomic Energy Research Institute in Gyeongju has reached 40,000 cumulative operating hours over 13 years since its first run in 2013 without a single safety accident, the Ministry of Science and ICT said. The facility supports radiation-environment testing for semiconductors and other applications. Operations expanded to a 24-hour service system from September 2024, and it supported 353 people and 210 experiments last year.
