摘　　要：碳纳米管绳是近年来才产生的超晶格结构的大单晶体。荷能带电粒子在碳纳米管绳内的沟道效应显示出大的沟道直径和微弱的退沟道因子。在粒子束物理的领域中,碳纳米管绳沟道的最迷人应用是:与在高梯度加速场里粒子加速的可能性相联系;与建造TeV对撞机的可能性相联系。本文介绍了这类应用研究的进展。The nanotubes-rope is a large single crystal with the super-lattice structure, and it has been recently produced. Channeling of energetic charged particle in the nanotubes-rope exhibits a large diameter of the channels and weak de-channeling factors. In particle-beam physics field, the most intriguing applications of the nanotubes-rope-channeling are connected with the possibility of particle acceleration in high gradient accelerating fields, and with the possibility of construction of TeV colliders. This paper introduces the progress of applied studies.
