介质laser驱动加速器偏转结构的模拟

Simulation of deflecting structures for dielectric laser driven accelerators

Willi Kuropka, Frank Mayet, Ulrich Dorda, Ralph Assmann

摘要:

在激光照射介质加速器(DLA)中,由于材料在光频下的高损伤阈值,可以实现高加速梯度。这是发展更紧凑的粒子加速器技术的必要条件。由戈登和贝蒂摩尔基金会资助的CHip国际项目的加速器正在研究这种设备。需要操纵光束的手段,即聚焦和偏转,以使这些装置正常工作。这些方法应该依赖于与加速结构相同的制造和动力技术。在这项研究中,不同的概念,介质激光驱动偏转结构的研究通过粒子在细胞(PIC)模拟和比较后。进行比较相对于光束操纵的适用性。另一个有趣的应用将被调查作为一个诊断设备的超短电子束从传统的加速器功能像一个射频横向偏转腔(TDS)。

英文摘要:

In laser illuminated dielectric accelerators (DLA) high acceleration gradients can be achieved, due to high damage thresholds of the materials at optical frequencies. This is a necessity in developing more compact particle accelerator technologies. The Accelerator on a CHip International Program funded by the Gordon and Betty Moore Foundation is researching such devices. Means to manipulate the beam, i.e. focusing and deflection, are needed for the proper operation of such devices. These means should rely on the same technologies for manufacturing and powering like the accelerating structures. In this study different concepts for dielectric laser driven deflecting structures are investigated via particle-in-cell (PIC) simulations and compared afterwards. The comparison is conducted with respect to the suitability for beam manipulation. Another interesting application will be investigated as a diagnostic device for ultra short electron bunches from conventional accelerators functioning like a radio frequency transverse deflecting cavity (TDS).
