实验结果表明，在等离子体中，一个长的粒子束团可以被一个短的、不对准的前束团驱动的尾场所诱导。软管开发的平面上的不对准，自调制的垂直平面，在频率接近等离子体电子频率，并且是可再现的。套管的发展取决于未对准方向，其生长取决于未对准程度和质子束团电荷。结果具有理论模型的主要特征，与其他基于等离子体的加速器相关，并代表了软管的第一个表征。
Experimental results show that hosing of a long particle bunch in plasma can be induced by wakefields driven by a short, misaligned preceding bunch. Hosing develops in the plane of misalignment, self-modulation in the perpendicular plane, at frequencies close to the plasma electron frequency, and are reproducible. Development of hosing depends on misalignment direction, its growth on misalignment extent and on proton bunch charge. Results have the main characteristics of a theoretical model, are relevant to other plasma-based accelerators and represent the first characterization of hosing.
