Description

In this study, we present the latest measurements of intrabeam scattering (IBS) effects at NSLS-II and compare them with particle tracking simulations using ELEGANT. The growth of horizontal and vertical emittances, as well as bunch length and energy spread, is observed as a function of single-bunch current. Simulations, including IBS and longitudinal wakefields modeled using a broadband impedance model, are used to explain these experimental observations. The same approach is applied to the low-emittance NSLS-II upgrade, where IBS significantly impacts the machine performance.
