International Muon Ionization Cooling Experiment MICE 1   MICE An International Muon Ionization Cooling Experiment TOWARDS A PROPOSAL preliminary logo

International Muon Ionization Cooling Experiment MICE 2 on 25 March, the MICE collaboration was invited to present a proposal to RAL, with the help of RAL since then RAL nominated a project engineer (Iouri Ivanichenkov) questions: What will MICE be? Who will do what? Who will pay what? When can/should this be done? MICE found a home! what will be the logo?

International Muon Ionization Cooling Experiment MICE 3 MICE Video Conferences and collaboration meetings MUCOOL/MICE Collaboration meeting Finalize who does what and cost estimates Schedule remaining open questions (decision tree) at that time the input to the proposal should be defined and proposal drafting underway.

International Muon Ionization Cooling Experiment MICE 10. Observed dark currents in 800MHz cavity in lab G. The cavity could not be run at a gradient higher than 5 MV/m without emitting one electron or more within a time window of 20 ns. (i.e mA) new curves indicate 10 MV/m Q. Is this the right figure of merit? with 200 MHz? Better probably: observed noise rate in actual detector near the cavity.

International Muon Ionization Cooling Experiment MICE 16 Simulation of performance of cooling cell fairly well understood. Now needed : … simulation of detector response, for design of e.g. downstream PID or to understand performance of Sci-Fi or TPG and first go at some systematics----- … groundwork by Janot needs to be extended … Yagmur has started with a GEANT4 version of MICE.  others (Steve Kahn, Vladimir Grichine, more needed) begin or volunteered to implement detector responses and reconstruction SIMULATIONS conceptual thinking of systematic uncertainties in the measurement needed

International Muon Ionization Cooling Experiment MICE 18 MICE : WHEN? GOAL: The long-term goal is to have a Conceptual Design Report for a Neutrino Factory Complex by the time of JHF and LHC start-up, so that, by that date, this would be a valid option for the future of HEP (European Muon Coordination and Oversight Group, April 2002) =2007 MICE must have measured cooling end 2006

International Muon Ionization Cooling Experiment MICE 23 Conclusions & discussion MICE has already shown to be a beneficial approach: RF emissions cost reductions safety windows.. etc.. There will be undoubtedly many other annoying discoveries, ….. followed by clever inventions MICE is essential to convince ourselves – and others – that we know how to build realistic cooling channels Getting a first measurement of cooling before LHC start-up should be feasible but requires good organization and priorities. Funding needs to be found also from outside MC. RAL is inviting us… we must take our chance.
