Medium size HPC clusters play an important role in the HPC landscape in that they provide both the training environment for system scalability and a flexible production field for a large class of numerical problems. In this poster we present CRESCO4, the latest medium size HPC cluster purchased by ENEA, in operation since few months. CRESCO4 is part of a(More)
The results of the CFD simulation of a tubular combustor for aero-engine applications developed by AVIO are presented. Simulations have been performed by using OpenFOAM. A Large-Eddy-Simulation approach is used to model turbulence; the compressible Smagorinsky model is used to describe Sub Grid Scale (SGS) motions and their interactions with the solved(More)
We present a measurement of the KL lifetime using the KLOE detector. From a sample of ∼ 4× 108 KSKL pairs following the reaction e+e− → φ → KSKL we select ∼ 15 × 106 KL → π0π0π0 decays tagged by KS → π+π− events. From a fit of the proper time distribution we find τL = (50.92 ± 0.17stat ± 0.25syst) ns. This is the most precise measurement of the KL lifetime(More)
A complete and detailed analysis of alpha spectra from the 222Rn and 220Rn progenies was performed by newly developed software. The software identifies the alpha peaks, performs appropriate fits and calculates the net area and its uncertainty, considering the entire background. The deconvolution of the overlapped peaks of 218Po and 212Bi allows us also to(More)
In the fixed energy environment of the ee collider DAΦNE, KLOE can measure the cross section of the process ee → hadrons as a function of the hadronic system energy using the radiative return method. At energies below 1 GeV, ee → ρ → ππ is the dominating hadronic process. We report here on the status of the analysis of the process ee → ππγ. Some preliminary(More)
From a sample of about 109 φ mesons produced at DA NE, we have selected KL mesons tagged by observing KS → π+π− decays. We present results on the major KL branching ratios, including those of the semileptonic decays needed for the determination of |Vus |. These branching ratio measurements are fully inclusive with respect to final-state radiation. The KL(More)
Muography is an imaging technique based on the measurement of absorption profiles for muons as they pass through rocks and earth. Muons are produced in the interactions of high-energy cosmic rays in the Earth's atmosphere. The technique is conceptually similar to usual X-ray radiography, but with extended capabilities of investigating over much larger(More)
