DLA中光束动力学的全光学控制

All Optical Control of Beam Dynamics in a DLA

David Cesar, Pietro Musumeci, R. Joel England

摘要:

介电激光加速利用纳米制造技术来构建光子结构以用于高梯度电子加速。在这些结构的小空间尺度特性,传统的加速器技术变得无效,在稳定的束流动力学。相反,我们提出了一个方案,通过直接调制驱动激光器来稳定运动,类似于射频四极杆。在这里,我们提出了一个可编程的“晶格”正在加州大学洛杉矶分校的飞马座实验室的设计。加速器接受未调制的3.5 MeV电子束,然后在2 cm的距离内将束聚束并加速1.5 MeV。

英文摘要:

Dielectric laser acceleration draws upon nano-fabrication techniques to build photonic structures for high gradient electron acceleration. At the small spatial scales characteristic of these structures conventional accelerator techniques become ineffective at stabilizing the beam dynamics. Instead we propose a scheme to stabilize the motion by directly modulating the drive laser, in analogy to a radio-frequency-quadrupole. Here we present a design for a programmable `lattice' being built at UCLA's Pegasus laboratory. The accelerator accepts an unmodulated 3.5 MeV electron beam and then bunches and accelerates the beam by 1.5 MeV over a distance of 2 cm.
