论文摘要
我们提出了一种新型的轴对称介电靶标，该靶标有效地浓缩了大部分材料中产生的Cherenkov辐射（CR），分为重点点的小附近。它可以称为“ CR的基于Axicon的集中器”。对于通过结构轴移动电荷轨迹的一般情况，通过电荷穿过讨论的散热器产生的辐射场的理论研究。在我们的先前论文中提出并发展了具有外表面特定特征的介电目标的想法。但是，与先前对这种目标的配置相反（对中心电荷轨迹进行了研究），当前版本可以从相对论粒子中有效地浓缩Cr能量，从而使该设备在各种应用中都具有前瞻性。
We propose a new type of axisymmetric dielectric target which effectively concentrates Cherenkov radiation (CR) generated in the bulk of the material into a small vicinity of focus point. It can be called the "axicon-based concentrator for CR". A theoretical investigation of radiation field produced by a charge moving through the discussed radiator is performed for the general case where a charge trajectory is shifted with respect to the structure axis. The idea of dielectric target with specific profile of the outer surface was presented and developed in our preceeding papers. However, contrary to the previous configuration of such a target (which was investigated for both centered and shifted charge trajectory), the current version allows efficient concentration of CR energy from relativistic particles, making this device extremely prospective for various applications.
