The Tuning System for the HIE-ISOLDE High-Beta Quarter Wave Resonator
P. Zhang, L. Alberty, L. Arnaudon +9
A new linac using superconducting quarter-wave resonators (QWR) is under construction at CERN in the framework of the HIE-ISOLDE project. The QWRs are made of niobium sputtered on…
Performance of a Downconverter Test-electronics with MTCA-based Digitizers for Beam Position Monitoring in 3.9 GHz Accelerating Cavities
T. Wamsat, N. Baboi, B. Lorbeer +1
Beam-excited higher order modes (HOM) in 3.9GHz accelerating cavities are planned to be used for beam position monitoring at the European XFEL. The selected HOMs are located around…
A Study of Beam Position Diagnostics with Beam-excited Dipole Higher Order Modes using a Downconverter Test Electronics in Third Harmonic 3.9 GHz Superconducting Accelerating Cavities at FLASH
P. Zhang, N. Baboi, N. Eddy +5
Beam-excited higher order modes (HOM) in accelerating cavities contain transverse beam position information. Previous studies have narrowed down three modal options for beam positi…
Study of Beam Diagnostics with Trapped Modes in Third Harmonic Superconducting Cavities at FLASH
P. Zhang, N. Baboi, R. M. Jones +1
Off-axis beams passing through an accelerating cavity excite dipole modes among other higher order modes (HOMs). These modes have linear dependence on the transverse beam offset fr…
Beam-based HOM Study in Third Harmonic SC Cavities for Beam Alignment at FLASH
P. Zhang, N. Baboi, H. Ecklebe +5
An electron beam entering an accelerator cavity excites higher order modes (HOM). These are radiated to HOM couplers and subsequently damped. They can also be used to facilitate be…
Higher Order Modes In Third Harmonic Cavities at Flash
I. R. R. Shinton, N. Baboi, T. Flisgen +4
Transverse modes in the 3.9 GHz cavities, designed and fabricated by FNAL, are reported on. These modes have the potential to cause significant emittance dilution if they are not s…
