Hom Spectrum and Q-factor Estimations of the High-beta Cern-spl-cavities*
نویسندگان
چکیده
Beam energy deposited in Higher-Order-Modes may affect both beam stability and cryo power requirements of superconducting proton linacs like those which are objective of the CERN SPL study. We report on numerical studies of the high-beta cavity type, analyzing it's HOM spectrum. These especially include Q-factor estimations based on scattering spectra calculations and an improved pole-fitting algorithm. The procedure is described in detail. Results are shown for a sample coaxial-type HOMcoupler without a fundamental mode filter.

Hom Couplers for Cern Spl Cavities
Higher-Order-Modes (HOMs) may affect beam stability and refrigeration requirements of superconducting proton linacs such as the SPL, which is studied at CERN as the driver for future neutrino facilities. In order to limit beaminduced HOM effects, CERN considers the use of HOM couplers on the cut-off tubes of the 5-cell superconducting cavities. These couplers consist of resonant antennas shaped...

In this paper we present the progress of the HigherOrder-Mode (HOM) coupler design for the high beta CERN SPL (Superconducting Proton Linac) cavities. This includes the RF transmission behavior as well as mechanical and thermal requirements and their optimizations. Warm RF measurements are presented for the rst four high beta SPL Cavities made of bulk niobium. Moreover the rst prototype of a HO...
متن کاملSome Considerations on the Choice of Frequency and Geometrical Beta in High Power Proton Linacs in the Context of Higher Order Modes
Several high power superconducting (SC) proton linear accelerators are currently in the design stage around the world, such as for example the European Spallation Source (ESS) in Lund, Project X at Fermilab, the European ADS demonstrator MYRRAH in Mol, and the Superconducting Proton linac (SPL) at CERN. In this contribution, the influence of Higher Order Modes (HOMs) in elliptical SC cavities i...

In order to set up a powerful proton source for a future Neutrino Factory, increasing at the same time the flux of protons available for new and existing facilities, CERN is studying a 2.2 GeV superconducting Hlinac for 4 MW beam power, called SPL. The superconducting part of this linac covers the energy range from 120 MeV to 2.2 GeV. Three sections made of 352 MHz cavities with nominal ß of 0....
متن کاملInvestigation of a High-q Dipole Mode at the Tesla Cavities
Higher order modes (HOM) can have a destructive influence on the beam emittance in the future linear colliders. Therefore it is important that the quality factor of the high impedance modes be damped under a safe level. Although attentive care was taken in designing the superconducting 9-cell cavities and the HOM couplers for the TESLA collider, a high Q and high impedance mode was discovered i...
