A Laser Ion Source (LIS) can produce high charge state and high intensity ion beams (∼emA), especially, refractory metallic ion beams, which makes it a promising candidate as an ion source for heavy ion cancer therapy facilities and future accelerator complexes, where pulsed high intensity and high charged heavy ion beams are required. However, it is difficult for the LIS to obtain a long pulse width while ensuring high current intensity, thus limiting the application of the LIS. To solve the conflict, magnetic fields are proposed to confine the expansion of the laser produced plasma. With a solenoid along the normal direction to the target surface, the lateral adiabatic expansion of the laser ablation plasma is suppressed which extends the pulse width of the ion beam effectively. The characteristics of laser ablation plasma with solenoid field confinement will be presented and discussed in this paper.

具有电磁场限制的激光烧蚀等离子体

激光离子源 (LIS) 可以产生高电荷态和高强度离子束 (∼emA),尤其是难熔金属离子束,这使其成为重离子癌症治疗设施和未来加速器复合物的离子源的有希望的候选者,需要高强度和高带电重离子束的脉冲。然而,LIS难以在保证高电流强度的同时获得长脉冲宽度,从而限制了LIS的应用。为了解决这一矛盾,人们提出了磁场来限制激光产生的等离子体的膨胀。通过沿靶表面法线方向的螺线管,抑制了激光烧蚀等离子体的横向绝热膨胀,从而有效地扩展了离子束的脉冲宽度。
