论文摘要
由激光加速产生的质子梁对于它们独特的空间（微米大小）和颞（皮秒）特性，这使得它们对于许多潜在的应用而言是可取的。但是，较大的能量扩散和发散角使得在交付后很难保持这些梁特性。这阻碍了激光加速的广泛应用。在本文中，我们根据弱化的磁体设计了双色调束翻译系统（DABTS），以实现水平和垂直方向上的可观传输，并同时压缩质子束的束长度。我们利用条纹角度和特殊的转向磁铁来有效地减少色差和高级非线性项的影响，并实现接近理想的点对点光学器件。我们认为，这项工作有助于将激光加速器应用于各种领域的持续努力。
Proton beams generated from laser acceleration show merit for their unique spatial (micron-size) and temporal (picosecond) properties, which make them desirable for many potential applications. However, the large energy spread and divergence angle make it difficult to maintain these beam properties after delivery. This hinders the wide application of laser acceleration. In this paper, we design a double achromatic beam translation system (DABTS), based on weak-focusing magnets, to realize achromatic transmission in both the horizontal and vertical directions, and compress the bunch length of the delivered proton beam at the same time. We make use of fringe angles and special steering magnets to effectively reduce the influence of chromatic aberrations and high-order nonlinear terms and realize close to ideal point-to-point optics. We believe this work contributes to the ongoing effort to apply laser accelerators to a variety of fields.
