高能量离子注入装置、射束平行化器及射束平行化方法
摘要：
本发明提供高能量离子注入装置、射束平行化器及射束平行化方法，适于高能量离子注入装置。射束平行化器(300)具备多个透镜部(310、312)，沿着基准轨道排列，以在射束平行化器的出口生成相对于基准轨道被平行化的射束。多个透镜部分别构成为，形成弓形弯曲间隙，并且通过施加于弓形弯曲间隙的电场来改变射束行进方向相对于基准轨道所成的角度。空间部(322、324)设置于多个透镜部中的一个透镜部和与该透镜部相邻的透镜部之间。空间部朝向被平行化的射束的与基准轨道垂直的剖面的短边方向。包括基准轨道在内的内侧区域通过空间部与多个透镜部的外侧区域连接。
摘要（英）：

A beam collimator includes a plurality of lens units that are arranged along a reference trajectory so that a beam collimated to the reference trajectory comes out from an exit of the beam collimator. Each of the plurality of lens units forms a bow-shaped curved gap and is formed such that an angle of a beam traveling direction with respect to the reference trajectory is changed by an electric field generated in the bow-shaped curved gap. A vacant space is provided between one lens unit of the plurality of lens units and a lens unit that is adjacent to the lens unit. The vacant space is directed in a transverse direction of the collimated beam in a cross section that is perpendicular to the reference trajectory. An inner field containing the reference trajectory is connected to an outer field of the plurality of lens units through the vacant space.
