Message-ID: <4206C7D8.8050609@neutrino.kek.jp> Date: Mon, 07 Feb 2005 10:43:52 +0900 From: koichiro Nishikawa <nishikaw@neutrino.kek.jp> Subject: [Fwd: January 2005 long-baseline neutrino newsletter] -------- Original Message -------- Subject: January 2005 long-baseline neutrino newsletter Date: Fri, 04 Feb 2005 13:16:57 -0600 From: Maury Goodman at Argonne <mcg@hep.anl.gov> To: LONGBNEWS@FNAL.GOV CC: MCG@hep.anl.gov Long-Baseline Neutrino News January 2005 numissue *** First NuMI event On January 21, 2005, during the first running of the NuMI beam at Fermilab with the target in, the first neutrinos were observed in the MINOS near detector. Timing, vertex, and angular distributions of the first event, and others that have followed, give confidence that these are real beam neutrinos. Many worked hard to make this happen, but congratulations should be sent to the MINOS spokespersons Doug Michael (mailto:michael@hep.caltech.edu), Stan Wojcicki (mailto:sgweg@slac.stanford.edu) and Beam Coordinator Robert Plunkett (mailto:plunk@fnal.gov). *** Fermilab neighbor web site As neutrinos start to make their way from Fermilab under Wisconsin to Minnesota, Fermilab expects some additional interest from citizens along the way. A web site has been put together for them at http://www.fnal.gov/neutrinos *** NuMI dedication planned Fermilab knows how to party, so the dedication of the NuMI facility is an excellent reason to do so. It is being planned for Dennis Hastert, Speaker of the House of Representatives to be present, so the date is not yet certain but the first week of March is a strong possibility. The new Secretary of Energy Samuel Bodman was sworn in on February 1st and there is a good chance that he will come as well. *** Young MINOS Young people, such as postdocs and graduate students will do much of the analysis work on MINOS. Young representatives have recently been added to the MINOS institutional board and the MINOS executive committee. *** Proton Driver CD0 The DOE might issue a site non-specific CD0 for a proton driver. CD0 is a bureaucratic prerequisite for future funding and constitutes a statement of mission need. Ideas for a proton driver, motivated by neutrinos, are being developed at BNL & FNAL. *** What's Driving the proton driver? A draft report from the proton driver working group at Fermilab will be out soon. There was a workshop at Fermilab where it was the consensus that the future neutrino program at Fermilab was the main motivation for a proton driver which could increase the proton intensity at Fermilab. There are other motivations as well, including Kaon physics, muon physics, etc. The working group has a web page at http://protondriver.fnal.gov/. They have recently moved their meetings to Wednesdays at 2:00. *** NOvA goes totally active The NOvA collaboration which has submitted a proposal for a large off-axis experiment in the NuMI beam has decided to adopt a Totally Active Scintillation Detector (TASD) based on liquid scintillator for the upcoming update to its proposal. An election is also being held for two co-spokespersons. The two candidates are John Cooper (Fermilab) and Gary Feldman (Harvard). *** A surprise for the new Fermilab Director The new Fermilab Director is alleged to have made a statement like the following: "You mean there's an off-axis beam about to turn on at Fermilab, and there is no off-axis detector to see it?" *** NUFACT05 June 21-26 in Rome. Neutrino factories aren't yet in anybody's budget, but NUFACT meetings seem to be where a lot of neutrino physics planning is done. http://www.lnf.infn.it/conference/2005/nufact05/home.htm This year's meeting is planned at Frascati. The fourth NUFACT summer institute will be June 12-20 in Capri, Italy near Naples. *** Notable New References (- web page at bottom for links) <-> G.T.
