This is the world’s smallest isochronous cyclotron for proton therapy, and its weight is 65 tons, which is 0.3 times that of our previous cyclotron model. The size is reduced by generating high magnetic fields using NbTi supercon-ducting coils cooled without cryogen. In addition, this cyclotron features the maximum beam current >1 uA and low power consumption <200 kW. The beam-commissioning test started at the end of 2020, the first extracted beam was observed in July 2021, and the basic performance of the beam was measured. The processes and results of the beam commissioning are reported.
