1. International cooling experiment 1 Towards an International Cooling Experiment Motivations: --Ionization cooling is an important ingredient in performance and cost of a neutrino factory --It has never been observed experimentally --It is a delicate design and engineering problem Goal --design, engineer, build a section of cooling channel that is part of a high performance neutrino factory design --put it in a beam and show that it works as expected (if not, understand why!) The beam never lies. This is a somewhat larger project that can be afforded by anyone of the worlds regions => International collaboration

2. International cooling experiment 2 Circa 10% cooling of 200 MeV muons requires  20 MV of RF single particle  measurement precision could be as good as  out /  in ) = 10 -3

3. International cooling experiment 3 Steering committee: Europe: A. Blondel*, H. Haseroth, R. Edgecock Japan : Y. Kuno + …. US: S. Geer, D. Kaplan, M. Zisman *convener for coming year charge: assemble « technical team » representing two regions in each of the following aspects.

4. International cooling experiment 4 Technical Team leaders for the ionization cooling experiment ================================================ These nominees in charge of task forces have the following chief responsabilities: a) organise the corresponding session for the workshop on 25-27 october b) assemble the necessary team c) if possible recommend a technical solution d) foresee a description of the design/performance/preliminary cost estimate of their part for the document to be issued mid-november

5. International cooling experiment 5 a) concept development and simulations : Alessandra Lombardi (Alessandra.Lombardi@cern.ch) Panagiotis Spentzouris (spentz@fnal.gov) b) Hydrogen absorbers: Shigeru Ishimoto ( shigeru.ishimoto@kek.jp) Mary-Anne Cummings ( macc@fnal.gov ) c) RF cavities and power supplies Bob Rimmer (rarimmer@lbl.gov) Roland Garoby (Roland.garoby@cern.ch) d) magnets Mike Green magreen@lbl.gov Helmut Haseroth helmut.haseroth@cern.ch (provisionally) e) particle detectors Vittorio Palladino vittorio.palladino@na.infn.it Alan Bross bross@fnal.gov f) beam lines Rob Edgecock edgecock@mail.cern.ch Claude Petitjean claude.petitjean@psi.ch g) RF radiation Jim Norem norem@anl.gov Ed McKigney e.mckigney@ic.ac.uk

6. International cooling experiment 6 Proposed agenda: 2001 Expose detectors to RF radiation (potential show stopper) write first description of experiment with two options US design (200 MHz) or CERN design (88 MHz) US simulate CERN scheme [and vice versa if possible] Evaluate availability and cost of main cost drivers: RF cavities / amplifiers/ power supplies/solenoids for each scheme evaluate beams + host labs 1st workshop 25-27 October 2001, CERN ! 16 Nov. 2001 ! Chose technology + host lab, write + submit proposal spring 2002 Technical proposal summer 2004 1st beam

7. International cooling experiment 7 16 NOVEMBER !!!??? YES... C. Petitjean from PSI needs our PROPOSAL by that date for distribution to the research committee that meets on january 8, 2001 This should be a PROPOSAL so that it be discussed by the committee. The proposal should include -- motivation for Neutrino Factory -- motivation for cooling experiement -- description of goals and expected results -- description of technical solution(s) envisaged. -- description of precise beam and space requirements and solutions at PSI -- preliminary cost estimate. Thus this is not a full technical proposal, to be finalized for spring 2002.
