Vitzro Nextech Achieves One-Hour Continuous Operation Certification for Klystron

Vitzro Nextech's klistron has successfully completed a one-hour continuous operation performance certification at the Pohang Accelerator Laboratory.

According to Vitzro Nextech on July 22, this test is a follow-up achievement after the localization and commercialization of klystron were announced last year. The purpose was to verify the applicability of domestically produced klystrons in actual accelerator operation environments. The test went beyond performance evaluation at the test building and was conducted on the main PAL-XFEL equipment. Vitzro Nextech's domestically developed klystron demonstrated one-hour continuous operation under conditions of 2.856 GHz S-band, 80 MW output, 4μs pulse width, and 60 Hz repetition rate.

A klystron is a high-power vacuum tube amplifier that converts and amplifies the energy of a high-voltage electron beam into microwave RF energy. The generated RF energy is supplied to the accelerating tube and used as the energy source to accelerate electrons to high energies. As such, klystrons are regarded as core RF power sources for large research facilities, including synchrotron accelerators, free electron lasers, and heavy ion accelerators.

In March 2016, Vitzro Nextech was selected for the Ministry of Science and ICT’s 'Accelerator Core Technology Development Project' and began joint development of localized klystrons together with the Pohang Accelerator Laboratory. Based on this achievement, the company aims to contribute to the self-reliance of the domestic accelerator core parts supply chain, and plans to expand its product application range to small and medium-capacity klystrons and similar high-power RF equipment in the future.

Byungho Lee, CEO of Vitzro Nextech, said, "This PAL-XFEL main facility performance certification is significant, as it proves the applicability of domestically produced klystrons in actual accelerator operation environments," adding, "Based on our accumulated capabilities in designing, manufacturing, and testing large-capacity klystrons over the past 10 years, we will contribute to self-reliance in the domestic accelerator supply chain and expand business opportunities into high-power microwave application fields such as medicine, industry, and defense."
