一种精确的束内散射简化模型
An Accurate, Simplified Model of Intrabeam Scattering
摘要:
从束内散射(IBS)的一般Bjorken-Mtingwa解出发,我们导出了一个精确的、大大简化的IBS模型,该模型适用于正常储存环晶格中的高能束。此外,我们表明,在相同的条件下,修改后的版本Piwinski的IBS制定(其中分散平方超过β已被取代的分散不变量)渐近接近的结果Bjorken-Mtingwa。
英文摘要:
Beginning with the general Bjorken-Mtingwa solution for intrabeam scattering (IBS) we derive an accurate, greatly simplified model of IBS, valid for high energy beams in normal storage ring lattices. In addition, we show that, under the same conditions, a modified version of Piwinski's IBS formulation (where dispersion squared over beta has been replaced by the dispersion invariant) asymptotically approaches the result of Bjorken-Mtingwa.
