KamLAND: A Liquid scintillator anti-neutrino detector at the Kamioka site
We present the initial design of a very large kton liquid scintillator detector to be installed in the underground cavity where Kamiokande used to be The ex periment is optimized to detect low energy anti neutrinos and it will perform unique measurements in the elds of neutrino physics geophysics and astrophysics One of the initial goals will be to perform a very long baseline oscillation experiment using a large number of nuclear reactors Such an experiment will be sensitive to neutrino masses as low as m eV attacking for the rst time with a laboratory measurement some of the possible solutions to the solar neutrino anomaly This can be considered the ultimate neutrino mass test using the oscillation technique The observation of neutrinos from the Earth supernovae atmosphere and nucleon decay will also be part of a very rich initial program while in a later stage the ob servation of solar neutrinos and other channels requiring ultra low background will become the main focus KamLAND is conceived as a scalable detector that will be able to start in a very short time to deliver results on a number of essential physics issues that only require present day technology This rst running period will also establish backgrounds and detector requirements for a second ultra low background running phase

title: The mass production and quality control of RPCs for the Daya Bay experiment
abstract: Resistive plate chambers will be used in the Daya Bay reactor neutrino experiment to help veto backgrounds created by cosmic-ray muons. The mass production of RPCs began in 2008 and by the end of 2009, 1600 RPCs (3500 m 2 ) had been produced and tested. This paper describes the production and quality control procedures, and quality assurance using cosmic-ray testing.

title: Physics of tau and charm
abstract: The physics of tau and charm started in early 70's after J/$\psi$ and $\tau$ were discovered. Since then several dedicated accelerators and experiments were built with increasing luminosities and studies on light hadron spectroscopy, charmonium, electroweak and QCD were never interupted. New interests and surprises are not rare in this area. With the newly built BEPCII/BESIII, an even brighter future is foreseen.

title: Inclusive J production in Z0 decays
abstract: Inclusive J production in Z0 decays is observed via the leptonic decay mode J → l+l− (l = e,μ). We measure the branching ratio Br(Z0 → J + X) = (4.1 ± 0.7 (stat.) ± 0.3 (sys.)) × 10−3. We have calculated the fraction of the J mesons from b-hadron decay and find a branching ratio of Br(b → J + X)= (1.3±0.2(stat.)±0.2(sys.)) × 10−2. We determine the average fractional energy of bottom hadrons 〈XE > = 0.70±0.03 (stat.)+0.02−0.01 (sys.) using the momentum spectrum of the J mesons. From a study of the angle between the J and the most energetic jet, we set an upper limit on the branching ratio Br ( Z 0 → q q g ∗ ; g ∗ → J + X ) −4 at 90% confidence level.

title: A water Cherenkov calorimeter for long baseline neutrino oscillation experiments
abstract: We propose a water-based large homogeneous calorimeter as the next generation neutrino detector for ν factories and/or conventional ν beams. The Cherenkov light produced in water is sufficient to have good energy resolution, and the pattern recognition is realized by a modular water tank structure. Monte Carlo simulations show that the detector performance is excellent for identifying neutrino CC events while rejecting backgrounds.

title: THE LIQUID SCINTILLATOR NEUTRINO DETECTOR AND LAMPF NEUTRINO SOURCE
abstract: A search for neutrino oscillations of the type ν μ → ν c has been conducted at the Los Alamos Meson Physics Facility using ν μ from muon decay at rest. Evidence for this transition has been reported previously. This paper discusses in detail the experimental setup, detector operation and neutrino source, including aspects relevant to oscillation searches in the muon decay-at-rest and pion decay in flight channels.

title: Development of multi-gap resistive plate chambers with low-resistive silicate glass electrodes for operation at high particle fluxes and large transported charges
abstract: Using electrodes made of semi-conductive glass is an innovative way of improving the rate capability of resistive plate chambers. To address this issue, we developed 6- and 10-gap counters with low-resistive silicate glass electrodes (bulk resistivity ∼10 10  Ω cm) suited for time-of-flight (TOF) applications at high rates and high transported charges. Measurements were performed at GSI-Darmstadt under uniform an irradiation by secondary particles stemming from proton reactions at 2.5 GeV/A. For the 10-gap MRPC, time resolutions below 90 ps and efficiencies larger than 90% were obtained at counting rates up to 25 kHz/cm 2 . When the particle flux increases every 5 kHz/cm 2 , the efficiency decreases by 1% and the time resolution deteriorates by 4 ps. A tolerable decrease of the material conductivity was also observed for a total transported charge of 1 C/cm 2 .

title: Development of thermionic-cathode RF electron gun at IHEP
abstract: A thermionic cathode RF electron gun has been developed at the Institute of High Energy Physics, Academia Sinica, China. The gun will accelerate and prebunch electrons emitted from a L/sub a/B/sub 6/ cathode using a high electric field in a resonant cavity. The gun was fabricated and tested, and used in the Beijing free-electron laser project. Results of experimental measurements of the injector performance of a prototype gun are also presented.<<ETX>>

title: New limits on the ultrahigh energy cosmic neutrino flux from the ANITA experiment.
abstract: We report initial results of the first flight of the Antarctic Impulsive Transient Antenna (ANITA-1) 2006-2007 Long Duration Balloon flight, which searched for evidence of a diffuse flux of cosmic neutrinos above energies of E(nu) approximately 3 x 10(18) eV. ANITA-1 flew for 35 days looking for radio impulses due to the Askaryan effect in neutrino-induced electromagnetic showers within the Antarctic ice sheets. We report here on our initial analysis, which was performed as a blind search of the data. No neutrino candidates are seen, with no detected physics background. We set model-independent limits based on this result. Upper limits derived from our analysis rule out the highest cosmogenic neutrino models. In a background horizontal-polarization channel, we also detect six events consistent with radio impulses from ultrahigh energy extensive air showers.

title: The specification of a multipole wiggler for CAMD
abstract: The growth of CAMD's research program over the last several years, in particular following the commissioning of a 7 T wiggler, has produced a demand for both higher beam brightness and flux density. Consequently, new insertion devices, such as a multi-pole wiggler (MPW), are being considered. A proposal has been submitted to the National Science Foundation for the funding of an MPW which would replace the existing 7 T wavelength shifter. The outline specification for this device is presented and also results of tests of modified optics for the CAMD storage ring which will be needed to accommodate the MPW. The modified optics have a reduced vertical aperture requirement of 20 mm at the location of the MPW.
