High-Power Target Station and Thermal Management
Using a high-speed rotating target made of tungsten-rhenium alloy with a fast heat exchange structure, the photon yield is increased tenfold. Liquid metal bearing technology is used to reduce thermal power density, ensuring continuous stable operation and safe maintenance.
- Rapid Replacement of High-Load Targets and Modular Expansion
- High-pressure helium cooling, water-cooled isolation multi-stage heat exchange
- The target-isotope target spacing is optimized to 1.5 cm, greatly improving photon utilization efficiency
- Adaptation of multi-nuclide preparation reaction pathways
- The recovery rate of Ra-226 reaches 90-98%, achieving raw material recycling
Ac-225 production process
Raw material supply
Multi-channel guarantee of stable supply of Ra-226 raw materials
Photoreaction
A 40 MeV electron accelerator produces high-energy photons that bombard the target, triggering photonuclear reactions.
Decay separation
Ra-225 decays into Ac-225, and Ac-227 impurities are removed through a multi-stage separation process to ensure radionuclide purity
Recycle and reuse
The recovery rate of Ra-226 reaches 90-98%, achieving raw material recycling and greatly reducing production costs.
GMP-grade separation and purification
The multi-stage separation process ensures the purity of radionuclides and the consistency of radiochemical indicators, meeting the quality requirements for medical isotopes.
Quality and Compliance System
Comprehensive quality control covering the entire process of production, packaging, and transportation, providing assurance for clinical collaboration and industrial delivery.
