THE TOP-IMPLART PROTON LINEAR ACCELERATOR: INTERIM CHARACTERISTICS OF THE 35 MEV BEAM

Area of Science:

• Medical Physics
• Particle Accelerator Technology

Background:

• The TOP-IMPLART project aims to construct a 150 MeV proton linear accelerator for advanced tumor radiotherapy.
• A key feature is modularity, enabling continuous beam characterization and performance enhancement during development.

Purpose of the Study:

• To characterize the preliminary dosimetry of the 35 MeV proton beam from the TOP-IMPLART accelerator.
• To assess the beam's stability and homogeneity using multiple dosimetry systems.

Main Methods:

• Utilized several dosimetry systems to measure beam characteristics.
• Evaluated short-term stability and homogeneity of the 35 MeV proton beam.

Main Results:

• Demonstrated short-term beam stability better than 3%.
• Achieved beam homogeneity better than 2.6%.
• Observed improved stability compared to the previous 27 MeV beam.

Conclusions:

• The 35 MeV proton beam from the TOP-IMPLART accelerator exhibits favorable preliminary stability and homogeneity.
• These results support the accelerator's potential for clinical application in proton therapy.
• The modular design facilitates ongoing optimization for future higher energy beams.
