Second Bulletin

### NuFact05 7th International Workshop on Neutrino Factories and Superbeams, Laboratori Nazionali di Frascati, (Rome) Italy

Aula Bruno Toushek (Auditorium)
21-26 June 2005

General Information

This is the last Bulletin before you arrive to Nufact05 where you will receive Bulletin III. Registration is still informally open until hotels will be helping us to accommodate the latecomers.

NuFact05 is the seventh annual Neutrino Factory workshop. This series of annual meetings is devoted to discussing the full physics potential of Neutrino Factories, Superbeams and Betabeams as well as the design and feasibility of the accelerator complex and the various detectors. The NuFact05 workshop starts on the morning of Tuesday June 21th and ends at lunch time on Sunday June 26, 2005. In conjunction with this workshop there will also be a summer school for students and other young scientist, the 4th International Summer School on Neutrino Factories and Superbeams, which will take place in Capri, from the morning of Sunday June 12 to lunch time Monday Jun  20, 2005. Tranfer of lectures and students to Frascati will take place on that Monday afternoon. For more information on the School: http://www.nufact05school.na.infn.it

The
general scientific background of NuFact consists of - the recent major discoveries that have proven that different flavors of neutrinos do oscillate into one another, providing the first clues of new physics beyond the standard model. They call for a complete determination of the neutrino mass splittings, of the neutrino mass hierarchy and of the neutrino mixing matrix (Pontecorvo-Maki-Nakagawa-Sakata matrix). Its yet-unknown third neutrino mixing angle $\theta_{13}$ will be precisely measured first, the ultimate goal being the measurement of its the CP violating phase d.   - recent developments of accelerator technology that are making possible to conceive of superior neutrino beams, based on the conventional concept of a pion decay tunnel,  as well as on the novel concept of a storage ring for longer lived high energy neutrino parents, for which the options of muons and radioactive ions are being investigated. All options rely on emerging technologies promising high-power proton accelerator beams of multi MegaWatt power and share the technical challenge of handling and exploiting efficiently this unprecedented high power.

The general purpose of the Workshops is to bring together yearly the communities that in the different regions of the world work towards the
long term goal of constructing new superior accelerator-based neutrino facilities. This year, these communities have prepared a proposal for a one year International Scoping Study, that will define the baselines options to be brought to a complete Design Study. We plan to launch it at Nufact05 and present its results at NuFact06. The last morning of the NuFact05 Workshop, Sun June 26, will be entirely devoted to this.

Scientific Program

The workshop consists of plenary talks and parallel working group sessions.
The  program of the plenary talks is being made available on the web at http://www.lnf.infn.it/conference/nufact05/ .

Four working group WG sessions are planned at NuFACT05.

WG1: Neutrino Oscillation Physics
WG2: Neutrino Non-oscillation Physics
WG3: Machine Design and R&D
WG4: Intense Muon Physics

Three convenors are assembling the scientific program of each working group (WG) . To contribute to any of the working group sessions, please contact one of conveners listed on the WG Web Page.

Workshop Site

The workshop will be held in the Laboratori Nazionali di Frascati, Italy, (www.lnf.infn.it).

Registration and Accommodation

All details of how to register for NuFact05, reserve accommodation and reach the Workshop Site have been long posted on the NuFact05 web-site (http://www.lnf.infn.it/conference/nufact05/).

A transportation bus will be available for participants to the
the 4th International NuFact Summer School to reach the Workshop site in the afternoon  of Monday June 20. We will board it at the harbour in Napoli and will drive to Frascati.
