AI Technical Summary
Traditional ion source beam tuning relies on manual operation, making it difficult to achieve a globally optimal solution. This results in poor beam performance, poor consistency and repeatability, low beam tuning efficiency, and difficulty in responding quickly to dynamic changes.
An automatic beam tuning method using an ion source is employed to monitor and adjust multiple control parameters in real time. The optimal adjustment parameters and amounts are determined through pulse width charge testing, and closed-loop control is achieved in conjunction with a radio frequency signal control device to ensure the stability and consistency of the proton beam.
This achieved stable and efficient acceleration of the proton beam, improved beam performance and system control precision, and ensured the reliability and consistency of the treatment process.
