Simulation of beam gas coulomb scattering in HALS
Yu Lu-Xin, Gao Wei-Wei, Wang Lin +1
In conventional research on the beam gas coulomb scattering (BGCS), only the related beam lifetime using the analytical method is studied. In this paper, using the PIC-MCC method,…
Analytic modeling of instabilities driven by higher-order modes in HLS II RF system with a higher-harmonic cavity
Yuning Zhao, Weimin Li, Congfeng Wu +1
The utility of a passive fourth-harmonic cavity plays key role in suppressing longitudinal beam instabilities in the electron storage ring and lengthens the bunch by a factor of 2.…
