Abstract: A boron neutron capture therapy device compatible with a rotating target and a fixed target and a target replacement method are provided, including a beam shaping body and a vacuum pipeline, where the beam shaping body includes a base platform, two sides of the base platform are each provided with a reflector module and a back reflector, and a compatible cavity capable of accommodating a rotating target module is disposed on the base platform; when the rotating target is adopted, the rotating target module is mounted in the compatible cavity, and the vacuum pipeline is connected with the rotating target module; and when the fixed target is adopted, the fixed target is detachably mounted on the vacuum pipeline. The boron neutron capture therapy device can meet the arrangement requirements of the fixed target and the rotating target at the same time, which is convenient for adjustment and updating of apparatuses.

Abstract: A fluid treatment device and method are provided for generating an electric field across a gap between first and second electrode and for concentrating the electric field within a fluid treatment chamber located in the gap.
