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 ...

Computer simulations for the CERN muon storage ring confirm the absence of beam-induced multipacting. Thus electron-cloud build up along the bunch train is not expected to be a problem. Geneva, Switzerland January 5, 2001 We first describe a few basic considerations on electron-cloud build up, scaling from the LHC, and then report simulation results. Table 1 lists relevant parameters for the CE...

B. Lee Roberts , Department of Physics, Boston University, Boston, MA 02215, USA for the Muon Collaboration[1] Abstract The Muon experiment, E821, at the Brookhaven AGS has the goal to measure the muon anomalous magnetic moment to a relative accuracy of . A superferric 14 m diameter storage ring has been constructed and an averaged magnetic field uniformity over the 90 mm diameter muon storage ...

A passive electrostatic recycling spectrometer for charged particles is described and demonstrated to store electrons with typical kinetic energies of tens of eV. The design of the charged particle optics and the basic operating characteristics of the storage ring are discussed. The storage lifetime achieved is approximately 50 micros, which is target gas pressure limited and corresponds to app...

We present a novel way to measure the friction force of an electron cooler in a heavy ion storage ring, which uses the counterforce provided by specially designed bunch potentials. Applying this method the friction force at small relative velocities between the electron and the ion beam has been determined with a 7.3 MeV beam of 9Be+ ions at the Heidelberg Test Storage Ring. The results are com...

We review the present developments in the design of ultra-low emittance storage ring light sources those having emittances approaching the diffraction limit for multi-keV X-ray production and the associated design challenges. An overview is presented of the design approaches for these 4 generation storage ring (4GSR) light sources now in construction or being studied for near-term implementatio...

The Advanced Photon Source (APS) is a 7-GeV full energy positron storage ring for generating synchrotron radiation with an injector. The booster synchrotron rf system consists of a single 1-MW klystron which drives four five-cell cavities at 352 MHz. The storage ring cavities consist of four groups of four single cells powered by two 1-MW klystrons for 100-mA operation. An overview of the opera...

Tantalus was a 240 MeV electron storage ring completed and commissioned in 1968. It was the first storage ring operated exclusively for the production of synchrotron radiation, although it was not designed for that purpose. As such, it influenced the operating pattern for subsequent dedicated sources of synchrotron radiation. Pioneering experiments using synchrotron radiation were carried out o...

The equations for spin evolution of a particle in a storage ring are obtained considering contributions from the tensor electric and magnetic polarizabilities of the particle along with the contributions from spin rotation and birefringence effect in polarized matter of an internal target. Study of the spin rotation and birefringence effects for a particle in a high energy storage ring provides...
