Neutron capture therapy system and neutron generation part recovery method therefor

A neutron capture therapy system, characterized in that the neutron capture therapy system comprises

• an accelerator configured to generate a charged particle beam,
• a transmission device configured to transmit the charged particle beam and comprising at least a first transmission part and a second transmission part,
• a neutron generation part configured to generate a neutron beam by reacting with the charged particle beam,
• a beam shaping body configured to perform spectrum adjustment on the neutron beam, and
• a guidance device,
• wherein the first transmission part is detachably connected to the second transmission part and comprises a first position and a second position,
• the neutron generation part is arranged on the first transmission part, and
• the guidance device is capable of guiding the first transmission part to move from the first position to the second position, and wherein
• when the first transmission part is located at the first position, the neutron generation part is accommodated in the beam shaping body and is capable of reacting with the charged particle beam to generate neutrons;
• and
• when the first transmission part is located at the second position, the neutron generation part is separated from the beam shaping body.
