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

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

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. Web site: thanks to Yagmur Torun -

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 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

International cooling experiment 5 a) concept development and simulations : Alessandra Lombardi Panagiotis Spentzouris b) Hydrogen absorbers: Shigeru Ishimoto ( Mary-Anne Cummings ( ) c) RF cavities and power supplies Bob Rimmer Roland Garoby d) magnets Mike Green Helmut Haseroth (provisionally) e) particle detectors Vittorio Palladino Alan Bross f) beam lines Rob Edgecock Claude Petitjean g) RF radiation Jim Norem Ed McKigney

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 October 2001, CERN ! 16 Nov ! Chose technology + host lab, write + submit proposal spring 2002 Technical proposal summer st beam

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.

International cooling experiment 8 Agenda of workshop october 2001 Should we have parallel or sequential team meetings? Workshop announcement:

International cooling experiment 9 Proposed date (s) for next video conf: 17 or 24 September, same time
