摘要:

TeV/m加速梯度使用晶体,如R. HEP的早期先驱Hofstadter仍然无法实现。尽管粒子通道效应对粒子加速有很好的影响,但由于碰撞能量损失和发射度降低以及严重的束流中断,阻碍了利用大块晶体进行粒子加速的努力。我们渴望将纳米科学与加速器科学结合起来,不仅要利用纳米结构管来克服这些问题,以避免束流对体离子晶格的直接影响,而且还要利用纳米材料的高度可调特性。我们开创了一种新的表面波机制,在纳米结构的材料与强大的静电组件,不仅达到几十TeV/m的梯度,但也有聚焦领域。在我们的倡议下,数十TeV/m梯度和光束纳米调制的原理验证正在进行中。可实现的纳米结构加速器自然为HEP以及利用高能粒子或光子束的广泛研究领域带来了新的视野。

英文摘要:

TeV/m acceleration gradients using crystals as originally envisioned by R. Hofstadter, an early pioneer of HEP, have remained unrealizable. Fundamental obstacles that have hampered efforts on particle acceleration using bulk-crystals arise from collisional energy loss and emittance degradation in addition to severe beam disruption despite the favorable effect of particle channeling along interatomic planes in bulk. We aspire for the union of nanoscience with accelerator science to not only overcome these problems using nanostructured tubes to avoid direct impact of the beam on bulk ion-lattice but also to utilize the highly tunable characteristics of nanomaterials. We pioneer a novel surface wave mechanism in nanostructured materials with a strong electrostatic component which not only attains tens of TeV/m gradients but also has focusing fields. Under our initiative, the proof-of-principle demonstration of tens of TeV/m gradients and beam nanomodulation is underway. Realizable nanostructure accelerators naturally promise new horizons in HEP as well as in a wide range of areas of research that utilize beams of high-energy particles or photons.
