摘要

空间电荷调整偏移会影响存储环的光束质量。拉斯莱特方法是计算空间电荷调谐偏移的经典方法，但对于束长极短、束间距极小的光环，例如稳态微束（SSMB）存储光环，该方法可能无法成立。为了克服这一局限，我们开发了适用于任意束长和束距的新公式，用于计算空间电荷调谐偏移。此外，我们还专门针对极短束长提供了空间电荷调谐偏移的简化计算公式。为了证明这些新推导公式的有效性，我们进行了数值计算。此外，这些公式还被应用于计算具有典型参数特征的 SSMB 储存环中的空间电荷调谐偏移。

Calculations of space-charge tune shifts in storage rings with extremely short bunches and small bunch spacing

Space-charge tune shifts can affect the beam quality in storage rings. Laslett’s method, a classical approach for calculating space-charge tune shifts, may not hold valid assumptions for rings with extremely short bunches and small bunch spacing, such as in steady-state microbunching (SSMB) storage rings. To overcome this limitation, we have developed new formulas that are suitable for arbitrary bunch lengths and spacings for calculating space-charge tune shifts. Additionally, simplified formulas have been provided for the calculations of space-charge tune shifts specifically in the context of extremely short bunch lengths. Numerical computations were carried out to demonstrate the validity of these newly derived formulas. Moreover, the formulas were applied to compute the space-charge tune shifts in an SSMB storage ring characterized by typical parameters.
