ESGARD-OMIA meeting

CERN, 11.09.2007

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)
