Abstract

The embodiment of the invention provides a neutron beam current device. The neutron beam current device is used for carrying out neutron energy spectrum adjustment on a neutron beam entering the neutron beam current device, wherein particles of the neutron beam comprise fast neutrons, epithermal neutrons, thermal neutrons and gamma photons. The neutron beam current device comprises a filtering part, an adjusting part and a collimator, wherein the filtering part is used for filtering fast neutrons in the neutron beam; the adjusting part is used for adjusting the neutron energy spectrum of the neutron beam so as to obtain an epithermal neutron beam or a thermal neutron beam; and the collimator is used for carrying out collimated emission on the adjusted neutron beam, wherein the filtering part, the adjusting part and the collimator are sequentially arranged in the neutron beam current device in a direction from a position that the neutron beam enters the neutron beam current device to aposition that the neutron beam is emitted out of the neutron beam current device. According to the neutron beam current device provided by the embodiment of the invention, two neutron beams, namely the thermal neutron or the epithermal neutron, can be provided through one beam current channel, so that two beam current channels do not need to be separately arranged, a larger space occupied by a plurality of beam current channels is avoided, and increase of construction cost is avoided.

Description

technical field [0001] The invention relates to the technical field of neutron irradiation therapy, in particular to a neutron beam device and a neutron irradiation device. Background technique [0002] Neutron capture therapy is to inject drugs such as boron-containing compounds that have an affinity with cancer cells to the tumor, and use neutron irradiation with a certain energy to cause fission of boron atoms and kill cancer cells. The types of neutron beams used in radiation therapy include thermal neutron beams and epithermal neutron beams, which are used to irradiate superficial and deep tumors in the body respectively. [0003] At present, neutron irradiators used to meet different irradiation requirements need to be provided with different neutron beam channels, for example, two beam channels are provided to provide thermal neutron beams and epithermal neutron beams respectively, which has the following disadvantages: A beam channel increases the occupied space, wh...
