The performance of the LHCb Muon system and its stability across full 2010 data taking with LHC running at ps = 7 TeV energy is studied. optimization detector setting time calibration performed first collisions delivered by described. Particle rates, measured for wide range luminosities beam operation conditions experienced during run, are compared values expected from simulation. space alignment detectors, chamber efficiency, resolution cluster size evaluated. found to be as specifications...

We have measured the cross section of radiative process e+e- -> pi+pi-gamma with KLOE detector at Frascati phi-factory DAPHNE, from events taken a CM energy W=1 GeV. Initial state radiation allows us to obtain for pi+pi-, pion form factor |F_pi|^2 and dipion contribution muon magnetic moment anomaly, Delta a_mu^{pipi} = (478.5+-2.0_{stat}+-5.0_{syst}+-4.5_{th}) x 10^{-10} in range 0.1 < M_{pipi}^2 0.85 GeV^2, where theoretical error includes SU(3) ChPT estimate uncertainty on photon final...

The electron-positron collider DAPhiNE, the Italian Phi factory, has been recently upgraded in order to implement an innovative collision scheme based on large crossing angle, small beam sizes at point, and compensation of beam-beam interaction by means sextupole pairs creating a "crab-waist" configuration region. Experimental tests novel exhibited increase factor 3 peak luminosity with respect performances reached before upgrade. In this Letter we present new scheme, discuss its advantages,...

Two high-accuracy goniometers equipped with two bent silicon crystals were installed in the betatron cleaning insertion of CERN Large Hadron Collider (LHC) during its long shutdown. First beam tests recently performed at LHC 450 GeV/c and 6500 stored proton beams to investigate feasibility halo collimation assisted by crystals. For first time channeling protons was observed a particle accelerator. A strong reduction losses due nuclear inelastic interactions aligned crystal comparison...

A reliable and highly scalable Internet of Things (IoT) end-to-end data infrastructure has been developed for environmental radiation monitoring at the European Organization Nuclear Research (CERN) based on a low-power wide-area network (LPWAN). The proposed system, called Waste MONitoring (W-MON), consists an interconnected thousands sensitive ultralow-power gamma sensors acting as long range (LoRa) transceivers. aim system is to improve automatize radiological controls conventional waste...

A study of crystal assisted collimation has been continued at the CERN SPS for different energies stored beams using 120 GeV/c and 270 protons Pb ions with per charge. bent silicon used as a primary collimator deflected halo particles channeling directing them into tungsten absorber. strong correlation beam losses in off-momentum intensity measured first high dispersion (HD) area downstream was observed. In conditions, loss rate induced by inelastic interactions nuclei is significantly...

We have studied the phi->a_0(980) gamma process with KLOE detector at Frascati phi-factory DAPhNE by detecting phi->eta pi^0 decays in final states eta->gamma and eta->pi^+ pi^- pi^0. measured branching ratios for both states: Br(phi->eta gamma)=(7.01 +/- 0.10 0.20)x10^-5 (7.12 0.13 0.22)x10^-5 respectively. also extracted a_0(980) mass its couplings to eta pi^0, K^+ K^-, phi meson from fit of invariant distributions using different phenomenological models.
