Monopole passband excitation by field emitters in 9-cell TESLA-type cavities
We present an extension of the calculation of dipole-mode driven beam break-up instabilities, as calculated in [V. Volkov, Phys. Rev. ST Accel.

| Summary: | We present an extension of the calculation of dipole-mode driven beam break-up instabilities, as calculated in [V. Volkov, Phys. Rev. ST Accel. Beams 12, 011301 (2009); PRABFM1098-440210.1103/PhysRevSTAB.12.011301V. Volkov, J. Knobloch, and A. Matveenko, Phys. Rev. ST Accel. Beams (to be published)PRABFM1098-4402], to the monopole fundamental mode passband. The excitation of these modes has been observed in 9-cell TESLA cavities on test stands without beam [G. Kreps et al., Proceedings of SRF2009 (HZB, Berlin, Germany, 2009), pp. 289–291] and the same effect has been observed in klystrons with high DC currents. |
