FP7 - IA EUROLUMI Network Walter Scandale, Frank Zimmermann ESGARD-OMIA meeting CERN,

what is EUROLUMI? = network supporting research activities in FP7, e.g. CNI on IR upgrade, IA JRAs on collimation, magnets, superconducting rf for SPL = building on the success of FP6 CARE-HHH = widely scaled-down version of earlier Design Study proposal EUROLUMI by F. Ruggiero and W. Scandale (requested 0.6 MEuros ~ only ~5% of the original DS budget!!) = European partner of US LHC Accelerator Research Program (US-LARP)
