HOM Choice Study with Test Electronics for use as Beam Position Diagnostics in 3.9 GHz Accelerating Cavities in FLASH
Nicoleta Baboi, Bastian Lorbeer, Pei Zhang +3
Higher Order Modes (HOM) excited by the beam in the 3.9 GHz accelerating cavities in FLASH can be used for beam position diagnostics, as in a cavity beam position monitor. Previous…
Higher order mode spectra and the dependence of localized dipole modes on the transverse beam position in third harmonic superconducting cavities at FLASH
Pei Zhang, Nicoleta Baboi, Roger M. Jones
An electron beam entering an accelerating cavity excites a wakefield. This wakefield can be decomposed into a series of multi-poles or modes. The dominant component of the transver…
Higher Order Modes for Beam Diagnostics in Third Harmonic 3.9 GHz Accelerating Module
N. Baboi, N. Eddy, T. Flisgen +4
An international team is currently investigating the best way to use Higher Order Modes (HOM) for beam diagnostics in 3.9 GHz cavities. HOMs are excited by charged particles when p…
Eigenmode Simulations of Third Harmonic Superconducting Accelerating Cavities for FLASH and the European XFEL
Pei Zhang, Nicoleta Baboi, Roger M. Jones
The third harmonic nine-cell cavity (3.9 GHz) for FLASH and the European XFEL has been investigated using simulations performed with the computer code CST Microwave Studio. The ban…
Simulations of higher order modes in the ACC39 module of FLASH
I. R. R. Shinton, R. M. Jones, Z. Li +1
This study is focused on the development of a HOM-based BPM system for the ACC39 module currently installed and in operation at FLASH. A similar system is anticipated to be install…
