Emittance growth of kicked and mismatched beams due to amplitude-dependent tune shift
E. Waagaard, V. Ziemann
We derive evolution equations for the first and second moments of an initially mismatched, coupled, and displaced arbitrary Gaussian phase-space distribution under the influence of…
Equilibrium parameters in coupled storage ring lattices and practical applications
Volker Ziemann, Andreas Streun
We calculate equilibrium emittances and damping times due to the emission of synchrotron radiation for coupled storage ring lattices by evaluating the projections of the commonly u…
RF gymnastics with transfer matrices
Volker Ziemann
We introduce transfer matrices to describe the motion of particles in the vicinity of the stable and unstable fixed points of longitudinal phase space and use them to analyze the t…
Beam parameters of a Möbius ring
Volker Ziemann
We describe a racetrack-shaped ring in which the cross-plane coupling can be continuously varied between an uncoupled configuration to a Möbius configuration, where the transverse…
MATLAB Simulations of the Helium Liquefier in the FREIA Laboratory
Elias Waagaard, Roger Ruber, Volker Ziemann
We describe simulations that track a state vector with pressure, temperature, and gas flow through the helium liquefier in the FREIA laboratory. Most components, including threeway…
Noninvasively improving the orbit-response matrix while continuously correcting the orbit
Ingvar Ziemann, Volker Ziemann
Based on continuously recorded beam positions and corrector excitations from, for example, a closed-orbit feedback system we describe an algorithm that continuously updates an esti…
