The network of resonant bar detectors gravitational waves resumed coordinated observations within the International Gravitational Event Collaboration (IGEC-2). Four are taking part in this Collaboration: ALLEGRO, AURIGA, EXPLORER and NAUTILUS. We present here results search for wave bursts over 6 months during 2005, when IGEC-2 was only observatory operation. implemented data analysis is based on a time coincidence among NAUTILUS; ALLEGRO reserved follow-up studies. amplitude sensitivity to...
By using embedded-atom-method interatomic potentials and molecular-dynamics simulations, we study the collision of a single ${\mathrm{Ag}}_{7}$ cluster on Pd(100) substrate, at impact energies in direction perpendicular to (100) surface ${\mathit{E}}_{1}$=20 eV (2.86 eV/atom) ${\mathit{E}}_{2}$=95 (13.6 eV/atom). Our results indicate that implantation occurs both energies, but it is more important ${\mathit{E}}_{2}$. As opposed what shown experimentally, little fragmentation takes place for...
We report on the present scientific run (04–05) of two detectors EXPLORER and NAUTILUS. The 04–05 started in March 2004. strain sensitivity is about 7 × 10−22 Hz−1/2 bandwidth 5 Hertz. for 1 ms bursts h = 3 10−19.
The dispersion curves of the p(3\ifmmode\times\else\texttimes\fi{}1)O-Ag(110) surface phonon modes along 〈001〉 direction have been measured by inelastic He-beam scattering and compared with results lattice-dynamical calculations assuming different structures. combined experimental-theoretical approach gives a strong suggestion for missing-row-type reconstruction substrate. This, together previous on p(2\ifmmode\times\else\texttimes\fi{}1)O phase, points to restructuring as common feature all...
The construction and the assembly of two end-caps ATLAS liquid argon electromagnetic calorimeter as well their test qualification programs are described. work described here started at beginning 2001 lasted for approximately three years. results tests performed before installation in LHC pit given. detectors now installed cavern, full being commissioned. complete coverage is powered with high voltage readout.
The HL-LHC project aims at increasing the LHC luminosity by a factor 10 beyond design value. installation of set RF Crab Cavities to increase bunch crossing angle is one key upgrades program. Two concepts, Double Quarter Wave (DQW) and Dipole (RFD) have been proposed are being produced in parallel for test SPS beam before next long shutdown CERN accelerator’s complex. In retained concept, two cavities hosted single cryomodule, providing thermal insulation interfacing with coupling, tuning,...
The ATLAS Experiment at LHC, CERN will utilize a large, superconducting, air-cored toroidal magnet system with long Barrel Toroid and two end cap toroids. Each toroid contain eight racetrack coils mounted as single cold mass in cryostat vessel of approximately 10 m diameter 5 width. toroids provide the magnetic field for muon detectors. operating current is 20.5 kA 0.25 GJ stored energy peak 4.1 T windings. This paper presents status End Cap Project. Cold assembly integration full mass, 120...
Many future particle colliders require beam crabbing to recover geometric luminosity loss from the nonzero crossing angle at interaction point (IP). A first demonstration experiment of with hadron beams was successfully carried out high energy protons. This breakthrough result is fundamental achieve physics goals LHC (HL-LHC) and circular collider (FCC). The expected peak gain (related collision rate) 65% for HL-LHC even greater FCC. Novel experiments proton in CERN's Super Proton...
We study the deposition and very first steps of nucleation growth Ag on Pd(100) with thermal energy atom scattering. This technique is a sensitive nonperturbing probe to surface point defects, which permits an in situ in-time monitoring deposition. The intention this paper give detailed description approach used our work. form specularly reflected helium signal as function coverage temperature compared theoretical curve, computed by solving system rate equations that describe formation...
We report here the preliminary results of search for gravitational wave bursts from 2003 run EXPLORER–NAUTILUS experiment. The total common measuring time was 149 days. detectors had a typical noise spectral amplitude about 2 × 10−21 Hz−1/2, bandwidth order 10 Hz and very good stability. derive new upper limit GW burst rate, 0.02 events/day hRSS ⩾ 10−19, discuss implication this result with respect to obtained 2001 run.
The two cryogenic resonant bar detectors of the ROG Collaboration, EXPLORER and NAUTILUS, have been taking data continuously with a high duty cycle for several years. We report here on status recent analysis in particular results burst searches year 2004.
The major upgrade of the energy and intensity existing ISOLDE REX-ISOLDE radioactive ion beam facilities at CERN requires replacement most post-acceleration equipment by a superconducting linac based on quarter-wave resonators housed together with solenoids in series four high-β two low-β cryo-modules. As well as providing optimum conditions for physics, cryo-modules need to function under stringent vacuum cryogenic conditions. We present detail design expected performance high- β...
The data collected during 2005 by the resonant bar Explorer are divided into segments and incoherently summed in order to perform an all-sky search for periodic gravitational wave signals. parameter space of spanned about 40 Hz frequency, over 23 927 positions sky. Neither source orbital corrections nor spindown parameters have been included, with result that was sensitive isolated neutron stars a frequency drift less than 6 × 10−11 s−1. No candidates found means present analysis, which led...
