Problems solved by technology

[0003] At present, compact cyclotrons have been widely used in scientific research and biomedicine, but these accelerators generally have the problem of low flow intensity, and can only accelerate a single type of particles, such as negative hydrogen particles. Therefore, they cannot meet the needs of large flow. Strong scientific research, biomedical experimental research, such as boron neutron capture therapy (BNCT) technology

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, the main structural components of the compact accelerator provided by the present invention include magnet system 5, negative hydrogen ion source 3, H 2 + Ion source 4, implantation system 2, high frequency system and extraction system 1, negative hydrogen particles and H 2 + Particles share the same injection system 2, magnet system 5, high frequency system and extraction system 1 during the acceleration process. Injection system 2 and magnet system 5 are set coaxially, negative hydrogen particles and H 2 + The particles are injected from the axial direction of the magnet system 5 respectively. Both kinds of particles are extracted by stripping. The high-frequency system mainly includes a high-frequency transmitter and a high-frequency cavity 8 (such as figure 2 As shown), the high-frequency cavity 8 is inst...

Abstract

The invention relates to a compact cyclotron for accelerating negative hydrogen and H2+, which comprise a magnet system, an injection system, a high-frequency system and an extraction system; the injection system is respectively connected with a negative hydrogen ion source and a H2+ ion source; and negative hydrogen particles and H2+ particles share the same injection system, the magnet system, the high-frequency system and the extraction system during the acceleration process. The compact cyclotron for accelerating negative hydrogen and H2+ not only can accelerate the negative hydrogen particles but also can accelerate the H2+ particles; the extraction of the two types of particles adopts a stripping extraction method; and when the H2+ particles are accelerated, the H2+ particles are stripped into 2 H+ ions, so that the extraction beam is doubled, the particle energy is halved, so as to obtain an intense proton beam, so as to achieve the effect of multiple purposes.

Description

technical field [0001] The invention relates to a cyclotron, in particular to a cyclotron for accelerating negative hydrogen, H 2 + compact cyclotron. Background technique [0002] A cyclotron is a device that uses a magnetic field to make charged particles perform cyclotron motion, and is repeatedly accelerated by a high-frequency electric field during the motion. Its basic structure includes a magnet system, an ion source, an injection system, and an extraction system. [0003] At present, compact cyclotrons have been widely used in scientific research and biomedicine, but these accelerators generally have the problem of low flow intensity, and can only accelerate a single type of particles, such as negative hydrogen particles. Therefore, they cannot meet the needs of large flow. Strong scientific research and biomedical experimental research, such as boron neutron capture therapy (BNCT) technology. Contents of the invention [0004] The purpose of the present inventi...
