Alexander Novokhatski (SLAC National Accelerator Laboratory)13/04/2016, 13:50AcceleratorsOralWe discuss the fine structure of the field dynamics of coherent synchrotron radiation (CSR). The details of the time-domain field distributions have been investigated using a recently developed method for the numerical solution of Maxwell’s equations for a very short bunch moving in a magnetic field. We have discovered a transverse variation of the particle energy loss in a bunch due to CSR...Go to contribution page

Dr Victor Smalyuk (Brookhaven National Laboratory)13/04/2016, 14:10AcceleratorsOralA comparative analysis of collective effects has been done for a dozen of operating low-emittance storage rings. The beam energy is in the range from 1.5 to 8 GeV, horizontal emittance - from 0.3 to 7 nm. Both single-bunch and multi-bunch effects have been analyzed including beam lifetime, collective instabilities, current-dependent bunch lengthening and betatron tune shifts. For the machines...Go to contribution page

Alessandro Drago (INFN)13/04/2016, 14:30AcceleratorsOralIn this presentation some preliminary considerations on the feedback systems for FCC-ee are developed. Bunch-by-bunch feedback systems have been designed in the last years for other e+/e- collider like PEP-II, KEKB, DAFNE, SuperB and SuperKEKB. In all these cases, similar approaches have been implemented, even if some design variations have been suitable or necessary for different reasons....Go to contribution page
