LB-20 is the first medium-to-high energy medical cyclotron product in the 'LB' series of cyclotrons, with an energy level exceeding 18 MeV. It is primarily aimed at large medical institutions and research institutes.

It meets the full clinical and research needs of large medical institutions and research institutes, and is also suitable for radiopharmaceutical production companies to address the problem of large-scale radionuclide production.

The LB-20 ion source system features entirely proprietary intellectual property, utilizing an integrated Panning ion source model with innovative power and mechanical design. ISS1101 boasts the industry's longest lifespan, capable of stable use for over 300 days* (*when operating at a 60μA beam current, with daily usage of 1 hours).

The fully automated solid target system employs unique engineering technology that allows the target plate to tilt automatically, enabling the beam to bombard the target material at an oblique angle. This design effectively increases the reaction area, boosting radionuclide yield per unit of time.

 Compactly designed and highly automated, the system adapts to various radionuclide production processes within the shielding based on user needs at different stages.

The radionuclide pipelines are installed using a ferrule design, preventing cross-contamination between radionuclides while allowing for faster and more convenient assembly and replacement.

The system is equipped with three-tier administrative accesses, enabling users to customize the setup and offering software features such as report inquiry, audit tracking, and more.

LB-20 employs the latest RF system technology in the industry, utilizing a solid-state RF source composed of multiple power amplifier modules. This replaces traditional vacuum tube RF sources, significantly improving the stability of the RF system. Since each power amplifier module operates independently, damage to one module will not cause a system outage, further ensuring the stable operation of the cyclotron.

The LB-20 dedicated shielding enclosure uses a combination of internal and external shielding layers to effectively absorb radiation such as neutrons and gamma rays. This reduces environmental impact according to laws and regulations, and lowers the environmental requirements for users.

Basic function areas include the cyclotron room, the equipment room, the control room, the gas cylinder room, pharmaceutical clean environment, etc. 

If equipped with a solid target system, an additional clean compressed air source interface with a pressure of no less than 0.7 MPa must be provided in both the cyclotron room (main unit area) and the hot cell area. A pressure gauge and pressure-reducing valve should be installed in the air supply line. Additionally, an extra 4N nitrogen gas interface with a pressure of no less than 0.3 MPa must be provided in the hot cell area.
