摘要
在同时考虑束流发射度和空间电荷效应情况下,推导出了轴对称强流离子束的最佳聚焦条件,并根据数值计算结果,绘制出了最佳聚焦条件下确定束腰半径、束腰位置和固定靶上最小束半径的通用关系曲线。
Taking beam emittance and space charge effects into account simultaneously, the optimal focusing condition for axial symmetric intense ion beams is derived, and a set of universal relationships for determining beam waist radius, beam waist position and minimum beam radius on target under the optimal focusing condition is given.
