Lanzhou Taiji Completes Key Commissioning of First Domestic Multi-Ion Therapy Device HiTS400
The first domestically produced multi-ion therapy device HiTS400, independently developed by Lanzhou Taiji and installed at Shandong Cancer Hospital, recently completed phased joint commissioning. After one week of operational testing, all beam parameters of the device met or exceeded contractual requirements, laying the foundation for subsequent clinical registration work. According to reports, HiTS400 is a medical ion accelerator independently developed by Lanzhou Taiji with full intellectual property rights. It can stably deliver four ion species: C^6+, H^+, He^2+, and O^8+, and is equipped with multi-angle fixed treatment nozzles and a lightweight superconducting heavy-ion rotating gantry, integrating modulated scanning technology to advance the development and application of multi-ion combined therapy devices. On August 14, 2026, the device obtained an amendment to its Radiation Safety License from the Ministry of Ecology and Environment, granting qualification for commissioning and operation. In the early morning of August 20, the equipment achieved stable acceleration and precise extraction of carbon ion beams. Measured data show that the particle number after synchrotron acceleration reached 3.26E9 ppp, the terminal particle number reached 3.02E9 ppp, the extraction efficiency was 92%, and beam stability was no less than 95%.
