Ideas of use the particle channeling in bent crystals for steer the beams have been checked up and advanced in many experiments. However, until now, this method of beam formation has limitations in application, since the channeling process involves beam particles with low angular divergence, limited by the angle of Lindhard. Here we describe the focusing crystals, which expand the boundaries of application of bent crystals at accelerators.

聚焦晶体在大型强子对撞机上的应用前景

在许多实验中，已经检验并提出了使用弯曲晶体中的粒子通道来控制光束的想法，并进行了改进。然而，直到现在，这种束形成方法在应用上仍存在局限性，因为引导过程涉及具有低角度发散的束粒子，受Lindhard角度限制。在这里，我们描述聚焦晶体，该晶体扩展了加速器中弯曲晶体的应用范围。
