Halo Formation in Spheroidal Bunches with Self-Consistent Stationary Distributions
A. V. Fedotov, R. L. Gluckstern, S. S. Kurennoy +1
A new class of self-consistent 6-D phase space stationary distributions is constructed both analytically and numerically. The beam is then mismatched longitudinally and/or transver…
Stability and Halo Formation in Axisymmetric Intense Beams
Robert L. Gluckstern, Sergey S. Kurennoy
Beam stability and halo formation in high-intensity axisymmetric 2D beams in a uniform focusing channel are analyzed using particle-in-cell simulations. The tune depression - misma…
Coupling Impedances of Azimuthally Symmetric Obstacles of Semi-Elliptical Shape in a Beam Pipe
Robert L. Gluckstern, Sergey S. Kurennoy
The beam coupling impedances of small axisymmetric obstacles having a semi-elliptical cross section along the beam in the vacuum chamber of an accelerator are calculated at frequen…
A General Approach for Calculating Coupling Impedances of Small Discontinuities
Sergey S. Kurennoy, Robert L. Gluckstern, Gennady V. Stupakov
A general theory of the beam interaction with small discontinuities of the vacuum chamber is developed taking into account the reaction of radiated waves back on the discontinuity.…
