目前锥形套圈辗扩技术只能一次成形一件，而且由于锥形套圈锥角使得芯辊应力集中严重。

Based on both the strong-weak model and the strong-strong model, the instability caused by ions in equilibrium is simulated, some useful results are obtained. The results include the relation between instability growth rate and neutralization factor, the relation between instability threshold and neutralization factor, and the incoherent tune shift, the tune spread, the ion cloud distribution, the ion loss mechanism, as well as the ion accumulation limitation in the storage ring. With this understanding, we have carried out theoretical and experimental study for some ion clearing methods and their effects for the HLS ring. The minimum static clearing voltage is determined through calculating beam electric field and measuring ion current.

在上述基础上，我们对各种离子清洗的方法及清洗效果进行了理论和实验的研究：通过计算束流电场和测量清洗电极上的离子流来确定直流清洗电极所需的最小清洗电压；通过测量离子引起的频移来计算储存环的中性化系数；用模拟计算和实验测量证实了高频清洗能有效地克服储存环上离子俘获不稳定性；对由高频剔除系统形成的储存环部分束团填充模式下的离子俘获问题进行了初步研究，证实采用束团部分填充模式能在一定范围内克服离子俘获效应；并对各种离子清洗方法进行了比较。
