Wake fields evaluation for beam collimators and the 60 pc electron beam at the compact ERL at KEK
/ Tanaka, O A (KEK, Tsukuba) ; Nakamura, N (KEK, Tsukuba) ; Obina, T (KEK, Tsukuba) ; Tanimoto, Y (KEK, Tsukuba) ; Miyajima, T (KEK, Tsukuba) ; Shimada, M (KEK, Tsukuba) ; Norvell, N P (SLAC)
In high-intensity particle accelerators, unwanted transverse and longitudinal wakefields arise when the high- charge particle beam passes through the narrow chambers or locations with small transverse apertures, such as collimator jaws. The transverse wake field may affect the beam emittance and the longitudinal wake field can cause the energy loss and the energy spread. [...]
