| Zusammenfassung: | The invention relates to a compact electron linear accelerator system for FLASH radiotherapy. The system comprises an electron gun which is configured to provide an electron beam current with high peak current intensity and carries out accelerating and bunching of the electron beam current; a resonance acceleration cavity system, wherein the resonance acceleration cavity system is configured to accelerate the electron beam current emitted by the electron gun so as to reach energy required by an outlet, and the resonance acceleration cavity system adopts an Nb3Sn radio-frequency superconducting cavity; a power source system, wherein the power source system is configured to provide high-frequency power for the resonance acceleration cavity system, so that the resonance acceleration cavity system forms an acceleration field required by acceleration; and a cooling system, wherein the cooling system is configured to take away heat generated by high frequency of the resonance acceleration cavity system, so that the |
