LANZHOU, China – A significant milestone was achieved at the National Laboratory of Heavy Ion Accelerator (HIRFL) in Lanzhou. On December 25, the IH-DTL2 (Interdigital H-Mode Drift Tube Linac) meticulously manufactured by Kelin Company successfully passed cold test acceptance at the Institute of Modern Physics (IMP), Chinese Academy of Sciences.

Through nearly two days of rigorous testing, the accelerator demonstrated outstanding performance across all critical parameters:

l Frequency accuracy fully met specifications

l Tuning range perfectly matched physical requirements

l Field distribution showed exceptional agreement with theoretical design

l Q-value (Quality Factor, key indicator of cavity energy efficiency) reached 90% of design specification

These results validate Kelin's profound technical expertise in accelerator manufacturing and confirm that the company's precision cavity fabrication capabilities have reached international standards.

As the core component of the under-construction injector for HIRFL's Sector-Separated Cyclotron (SSC), the IH-DTL2's performance is crucial to the injector's operational success and carries significant implications for the national laboratory's sustainable development. Recognizing this responsibility, Kelin deployed its premier technical team throughout the project, employing advanced manufacturing processes and implementing stringent quality control measures. This approach enabled the company to overcome numerous technical challenges while ensuring world-leading product quality and performance.

The IH-DTL2's exemplary cold test performance not only affirms Kelin's technical prowess but also demonstrates the company's commitment to supporting China's major scientific infrastructure. Moving forward, Kelin will continue leveraging its technical advantages while increasing R&D investment to provide more high-quality, reliable products and services that advance domestic innovation in scientific equipment.
