MICE VC Alain Blondel, April MICE exectutive board met on 1 April 2004 after the collaboration meeting and remarked the very large amount of excellent work performed by all in the collaboration. The EB reflected on the orientations and aims of the MICE collaboration until the RAL collaboration meeting October I Technical document, cost estimate and Gateway 2 II Technical choices to be made III understand how to achieve 'measurement of emittance ratio to '

MICE VC Alain Blondel, April consolidation of the work done until March 2004 and GATEWAY 2 A. Finish the Technical Reference Document (‘rebaselining’). Paul Drumm sets end-of-april as a good goal for this. N.B. From there onwards we should use the change control procedures to suggest, design and implement improvements to the design of MICE. B. Finalize a more refined evaluation of cost estimates including two scenarios: a. what we think we could do right-now using solutions that are at hand. b. what we hope to be able to achieve with further work The aim being to be able to do better at lower cost, if possible. The line between categories a. and b. will evolve with time, normally this difference should shrink.

MICE VC Alain Blondel, April The goal is to achieve a realistically funded scenario allowing us to reach stage V of the development of MICE, in order to present ourselves with a solid case to the next step in the UK review process: GATEWAY 2. Step VI which allows much richer possibilities remains the ultimate goal but may have to be presented as an upgrade at a later stage. (in other words: as soon as we realize that we can reach step V we already have a highly worthwhile experiment and we should go to Gateway 2) The success of this process hinges to a large extent on the success of the funding proposals in the US and in Europe. USA : review foreseen end of May (when?) Italy : need meeting with head of INFN GATEWAY 2

MICE VC Alain Blondel, April  - STEP I: spring 2006 STEP II: summer 2006 STEP III: winter 2007 STEP IV: spring 2007 STEP V: fall 2007 STEP VI: 2008

MICE VC Alain Blondel, April Technical choices to be made. A certain number of technical choices need to be made following the progress that has been made up to the collaboration meeting (these so far enter in category 1.b. above) 2.a finalize decision on cryocoolers. 2.b finalize RF system design and costing. 2.c finalize validation of tracker. It is believed that these milestones can be achieved before or at the collaboration meeting in OSAKA in summer 2004 (2-4 August) for approval at the collaboration board at that time.

MICE VC Alain Blondel, April Understand the measurement of emittance ratio to This requires 3.a a full and operational simulation of the experiment 3.b design of monitoring systems that allow control of the physics parameters of the experiment to the desired accuracy. This programme of work is a major enterprise and will require collective focus until the end of October It is suggested to start from the table of quantities to be monitored and controlled (see the talks by Mary Anne and myself and the collaboration meeting). The proposed time table is as follows. -- for the meeting in OSAKA each working group should propose one or several ways by which the quantities can be conceptually controlled. -- for the RAL meeting a more detailed design should be proposed so as to include the controls in the final designs.
