Hi Lumi LHC Open Meeting Steve Myers Director

Hi. Lumi LHC Open Meeting Steve Myers Director of Accelerators and Technology, CERN

Welcome! • Very important project for physics Goal is to allow ~250 - 300 fb-1 per the future of high energy year with a peak luminosity of ~5 E 34 and using luminosity levelling – emerged after the decision in Chamonix to stop the “phase 1” upgrade – Very important progress has been made since then under the capable project leadership of Lucio Rossi • Collaboration is the key word (EC design study) – The proposal received the maximum rating from the EC – 14 European partners and non-EU partners including the US, Japan. – Many interesting technologies • High field sc magnets and cryogenics • SC RF (crab cavities), collimation, (R 2 E) sc links, . . .

Important Offshoot: HE-LHC • Possibility for the Long term Future (circa 2033) – Needs very high field dipoles (~20 T) – Protons with “fast” synchrotron damping – Impact of synchrotron radiation • Vacuum • Cryo • Emittance, luminosity levelling beam. .
