AB  - A compact AVF cyclotron of 240 MeV is under-designed for proton therapy. In order to reduce the size, the weight and operation cost, two superconducting coils are designed to implement the 2.35T central field. And the magnet weight is about 90 tons. The constant gap between the sectors is considered without deteriorating the beam stability. A dedicated design on extraction zone is performed to make the average field to close the isochronous field. The extraction efficiency is expected higher than 80%, by regulating the 1st harmonic field and arranging the extraction elements properly. In order to avoid the large scale of volume helium explosion in the quench, the low temperature superconducting coil using NbTi/Cu wire is cooled by 4K GM Cryocooler in a helium volume limiting design. The paper will present the physical design of this cyclotron.
