Low Emittance Rings Workshop 2011 (LowERing2011)

Europe/Zurich
Description
The goal of the workshop is to bring together experts from the scientific communities working on low emittance lepton rings. This includes damping rings, test facilities for linear colliders, B-factories and electron storage rings. The theme will be common beam dynamics and technology challenges for producing and controlling ultra-low emittance beams and the participants will benefit from the experience of colleagues who have designed, commissioned and operated such rings. This is the second in a series of workshops initiated in 2010 (http://ler2010.web.cern.ch), by the joint CLIC/ILC working group on damping rings. During the 1st workshop and subsequent discussions, it was found that the state of the art in the design of accelerator systems in X-ray storage rings approaches the goals of linear collider damping rings and future e+/e- circular collider upgrade projects. This workshop specifically targets the strengthening of interactions within the low emittance ring community by forming a LOWεRING collaboration network. Workshop sessions will include: Low emittance optics design and tuning -Low emittance cells design -Non‐linear optimization -Minimization of vertical emittance Collective effects reduction through lattice design -Collective Effects and beam instabilities -Electron cloud effect and fast ion instability -Intrabeam Scattering -Impedances -Coherent Synchrotron Radiation Low emittance Ring Technology -Insertion devices, magnet design and alignment -Fast kicker design -RF systems -Instrumentation for low emittance -Feedback systems -Vacuum technology
