Closed Orbit Instability for Strong Focusing Lattice ∗
We extend analysis of Ref. [1] of the closed orbit instability driven by the resistive wall impedance for the case of strong focusing lattice. A numerical estimate for the Low Energy Ring of PEP-II shows that the threshold current is three times higher than the nominal one. ∗Work supported by Department of Energy contracts DE–AC03–76SF00515 and DE–AC02–76CH03000
متن کاملBeam-beam Diagnostics from Closed-orbit Distortion
We study the applicability of beam-beam deflection techniques as a tuning tool for asymmetric B factories, focusing on PEP-II as an example. Assuming that the closed orbits of the two beams are separated vertically at the interaction point by a local orbit bump that is nominally closed, we calculate the residual beam orbit distortions due to the beam-beam interaction. Difference orbit measureme...
متن کاملUsing Local Bumps for correcting the SIS18 Closed Orbit
In the framework of the SIS18 upgrade several measurement campaigns on the closed orbit (CO) and its correction were carried out in February-May 2006. The CO correction is important for machine operation: the better the CO is corrected, the fewer beam loss occurs during operation due to increase of the machine’s acceptance. CO errors are also relevant for feed down effects of multipoles, which ...
متن کاملLattice Diagnostics Using Single Kick Closed Orbit at Kekb
We have measured beta functions using single kick closed orbit at KEKB. The measured beta functions were compared with the model lattice and gradient errors were extracted from the result in a beta beat. The gradient errors were also obtained by changing strength of steering magnets and measuring beam positions as the second method. The methods of the error estimation and preliminary results wi...
متن کاملFinitely Represented Closed Orbit Subdynamics for Commuting Automorphisms
The purpose of this paper is to exhibit highly structured subdynamics for a class of non-expansive algebraic Z-actions based on the closed orbits of elements of an action. This is done using dynamical Dirichlet series to encode orbit counts. It is shown that there is a distinguished group homomorphism from Z onto a finite abelian group that controls the form of the Dirichlet series of elements ...
