Principle of Skew Quadrupole Modulation to Measure Betatron Coupling*
The measurement of the residual betatron coupling via skew quadrupole modulation is a new diagnostics technique that has been developed and tested at the Relativistic Heavy Ion Collider (RHIC) as a promising method for the linear decoupling on the ramp. By modulating the strengths of different skew quadrupole families the two eigentunes are precisely measured with the phase lock loop system. Th...
متن کاملCorrection of the Betatron Coupling and Closed Orbit Distortion at the Vepp-2000 Collider
An essential condition for the round beam mode operation at the VEPP-2000 storage ring is the zero betatron coupling in the arc between two Interaction Points. To comply with this requirement the closed orbit should be corrected and the proper skew quadrupole correction system must exist. This work presents the development of the dipole and skew quadrupole correction systems for VEPP-2000. The ...
متن کاملSkew Quadrupole Focusing Lattices and Applications
In this paper we revisit using skew quadrupole fields in place of traditional normal upright quadrupole fields to make beam focusing structures. We illustrate by example skew lattice decoupling, dispersion suppression and chromatic correction using the neutrino factory Study-II muon storage ring design. Ongoing BNL investigation of flat coil magnet structures that allow building a very compact ...
متن کاملNuclear Quadrupole Coupling Tensors
By single crystal NMR the nuclear quadrupole coupling constants eQ,.h~ (H), the asymmetry parameters >/(H) and the dircetion cosines of the principal axes of the electric field gradient tensors of the H atoms of the two kinds of D 2 0 molecules have been determined at 295 K in RbAl(S04)2 • 1 2 D 2 0 . The results show that the D 2 0 molecules surrounding the ion Al + are "static" within the ...
متن کاملEstimation of Betatron Coupling and Vertical Dispersion for Spring-8 Storage Ring
The betatron coupling is one of the most important parameters of storage rings for high brilliant light source. By the precise alignment of the magnets [1] and the proper COD correction [2], the SPring-8 storage ring succeeded in achieving the very small linear betatron coupling without skew quadrupole corrector magnets. To prove this fact, we study the betatron coupling of the SPring-8 storage...
