Embodiment Construction
[0060] Considering that low-energy particle irradiation can meet the dose requirements, the use of low-energy particle accelerators for biological irradiation can be used as a research direction. However, for the beam emission of low-energy particles, there are the following technical difficulties: on the one hand, due to the Compared with high-energy particles, the energy of low-energy particles is very low. Based on the existing window sealing structure, it is impossible to realize the emission of some light particles with small atomic mass, or some particles will lose a lot of energy during the emission process, resulting in an extremely long range. Short, making it impossible to carry out biological radiation experiments or cancer treatment.
[0061] In view of this, the present disclosure provides an isolation window structure and device for extracting low-energy charged particles, based on the setting of the sealing film, the grid-like lining structure and the gap between...
