VERITAS is an array of four, 12-m-diameter, Cherenkov telescopes, designed to explore the very-high-energy gamma-ray sky in the energy band between 100 GeV and 50 TeV. Its construction and commissioning have occurred over the past two years and the array has been taking scientific data with three or more telescopes since November 2006. We present results from observations made with VERITAS during the 1 past observing season, including new results on the distant blazar 1ES1218 + 304, the active galaxy M87 and the high-mass X-ray binary system LS I +61 303. We also describe the plans in place for the coming observing seasons.


Cosmic tests and performance of the ATLAS SemiConductor tracker barrels
Demirköz, Melahat Bilge (Elsevier BV, 2007-03-01)
ATLAS is a multi-purpose particle detector for the LHC and will detect proton collisions with center of mass energy of 14 TeV. Part of the central inner detector, the SemiConductor Tracker (SCT) barrel, is now fully integrated with the Transition Radiation Tracker (TRT) barrel. The SCT module performance has been measured after module production, after macro-assembly of modules onto barrels, after arrival at CERN and again partially after integration with the TRT. The module noise average per channel has be...
Strange particle production in pp collisions at root s=0.9 and 7 TeV
Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2011-05-01)
The spectra of strange hadrons are measured in proton-proton collisions, recorded by the CMS experiment at the CERN LHC, at centre-of-mass energies of 0.9 and 7TeV. The K-S(0), A, and Xi(-) particles and their antiparticles are reconstructed from their decay topologies and the production rates are measured as functions of rapidity and transverse momentum, p(T). The results are compared to other experiments and to predictions of the PYTHIA Monte Carlo program. The p(T) distributions are found to differ subst...
Overview of the beam emission spectroscopy diagnostic system on the National Spherical Torus Experiment
Smith, D. R.; Feder, H.; Feder, R.; Fonck, R. J.; Labik, G.; McKee, G. R.; Schoenbeck, N.; Stratton, B. C.; Uzun Kaymak, İlker Ümit; Winz, G. (AIP Publishing, 2010-10-01)
A beam emission spectroscopy (BES) system has been installed on the National Spherical Torus Experiment (NSTX) to study ion gyroscale fluctuations. The BES system measures D-alpha emission from a deuterium neutral heating beam. The system includes two optical views centered at r/a approximate to 0.45 and 0.85 and aligned to magnetic field pitch angles at the neutral beam. f/1.5 collection optics produce 2-3 cm spot sizes at the neutral beam. The initial channel layout includes radial arrays, poloidal arrays...
Studies of jet mass in dijet and W/Z plus jet events
Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2013-05-01)
Invariant mass spectra for jets reconstructed using the anti-k(T) and Cambridge-Aachen algorithms are studied for different jet "grooming" techniques in data corresponding to an integrated luminosity of 5 fb(-1), recorded with the CMS detector in proton-proton collisions at the LHC at a center-of-mass energy of 7 TeV. Leading-order QCD predictions for inclusive dijet and W/Z+jet production combined with parton-shower Monte Carlo models are found to agree overall with the data, and the agreement improves wit...
Spectroscopy of the ODD-ODD nucleus 76As and its supersymmetric description
Hoyler, F.; Jolie, J.; Colvin, G.G.; Börner, H.G.; Schreckenbach, K.; Van Isacker, P.; Fettweis, P.; Göktürk, H.; Dehaes, J.C.; Casten, R.F.; Warner, D.D.; Bruce, A.M. (Elsevier BV, 1990)
Gamma rays and conversion electrons following thermal-neutron capture in 75As have been measured using the Ge pair spectrometer PN4, the bent crystal spectrometers GAMS and the β-spectrometer BILL at the ILL. Coincident γ-rays were recorded at the CEN/SCK Mol, and average resonance capture at En = 2 and 24 keV has been studied at the HFBR of BNL. The neutron binding energy in 76As was determined to be 7328.498 ± 0.075 keV. The resulting level scheme for 76As greatly improves the knowledge on this odd-odd nu...
