Analysis of the microbunching instability in a mid-energy electron linac
Dazhang Huang, Qiang Gu, Zhen Wang +2
Microbunching instability usually exists in the linear accelerator (linac) of a free electron laser (FEL) facility. If it is not controlled effectively, the beam quality will be da…
Plasma effect in the longitudinal space charge induced microbunching instability for low energy electron beams
Dazhang Huang, King Yuen Ng, Qiang Gu
The microbunching instability usually exists in the LINAC of a free electron laser (FEL) facility. In many cases, the longitudinal space charge (LSC) is a dominant factor that gene…
Study of microbunching instability in the linac of a soft X-ray FEL Facility
Dazhang Huang, Qiang Gu, Meng Zhang +2
The development of the microbunching instability is studied for the linac of the proposed Shanghai Soft X-ray Free-Electron-Laser facility (SXFEL) by analytic formulae as well as n…
Application of a Localized Chaos Generated by RF-Phase Modulations in Phase-Space Dilution
S. Y. Lee, K. Y. Ng
Physics of chaos in a localized phase-space region is exploited to produce a longitudinally uniformly distributed beam. Theoretical study and %numerical simulations are used to stu…
Fast beam stacking using RF barriers
W. Chou, D. Capista, J. Griffin +2
Two barrier RF systems were fabricated, tested and installed in the Fermilab Main Injector. Each can provide 8 kV rectangular pulses (the RF barriers) at 90 kHz. When a stationary…
Impedances of Tevatron Separators
K. Y. Ng
The impedances of the Tevatron separators are revisited and are found to be negligibly small in the few hundred MHz region, except for resonances at 22.5 MHz. The latter are contri…
