TeV Laser加速的机会
Opportunities for TeV Laser Acceleration
摘要：
确定了一组用于激光，等离子体和加速器技术的棒球场参数，这些参数定义了高达TeV的电子能量。这些粗略的参数是从控制激光加速的基本标度律中分割出来的，近年来在很大范围内从理论上提出并进行了实验探索。在10^{16} cm^{-3}数量级的密度范围内，我们发现适当的激光技术与高效高通量LD驱动Yb陶瓷激光器的技术匹配良好。此外，集体加速技术适用于紧凑的束停止阶段，通过采用束等离子体波减速，这有助于显着提高停止功率和能量回收能力的束。因此，我们找到了这些标度律和新兴激光技术所要求的激光加速参数的汇合点。这可能预示着一种新技术在风能领域的应用。
英文摘要：
A set of ballpark parameters for laser, plasma, and accelerator technologies that define for electron energies reaching as high as TeV are identified. These ballpark parameters are carved out from the fundamental scaling laws that govern laser acceleration, theoretically suggested and experimentally explored over a wide range in the recent years. In the density regime on the order of 10^{16} cm^{-3}, the appropriate laser technology, we find, matches well with that of a highly efficient high fluence LD driven Yb ceramic laser. Further, the collective acceleration technique applies to compactify the beam stoppage stage by adopting the beam-plasma wave deceleration, which contributes to significantly enhance the stopping power and energy recovery capability of the beam. Thus we find the confluence of the needed laser acceleration parameters dictated by these scaling laws and the emerging laser technology. This may herald a new technology in the ultrahigh energy frontier.
