[en] After the successful test flight in 1998, the AMS experiment has been redesigned to improve its performances for future operation on the ISS. The Silicon Tracker is the central detector of the AMS-02 magnetic spectrometer. Eight planes of double-sided microstrip detectors embedded in a magnetic field of ∼0.8 T allow for an accurate 3D reconstruction of particles trajectories and their rigidity measurement up to several TVs. The tracker is made of ∼6.4 m² of silicon with a single point resolution of 10(30) μm in the bending (not bending) coordinate. The description of the tracker system and its performance will be presented

[en] The Gamma-ray Large Area Telescope (GLAST) is a high energy (5 KeV - 300 GeV) γ-ray astronomy mission planned for launch in September 2007. The study of detected spectra of γ-rays is fundamental for the understanding of acceleration, emission, absorption and propagation mechanism of very high energy particles. This energy region has not been covered by any other experiment after the end of EGRET, which has performed the first survey of the full gamma-ray sky. Compared to previous instruments the telescope has a greatly improved sensitivity of 2x10^-9photonscm^-2s^-1(above 100 MeV for a 2 years all sky survey) and ability to localize γ-ray point sources. In this paper topics of interest for GLAST, like active galactic nuclei, unidentified sources, gamma ray bursts and study of the cosmic ray acceleration will be reviewed, as well as the status of the Large Area Telescope (LAT)

[en] A detector for a super B Factory will be described, in particular its baseline design and the possible improved option. Part of the BABAR detector will be reused, with the necessary upgrades in order to match the new requirements of an accelerator operating at a luminosity of 10³⁶ cm^-2s^-1. The progress made in the R D of the different detectors will be presented. In particular the studies for the vertex detector (SVT) and the forward electromagnetic calorimeter will be discussed.

[en] The Large Area Telescope (LAT) has been integrated and is currently under test to be ready for launch by NASA in 2008, as the main instrument on the Gamma-ray Large-Area Space Telescope (GLAST) mission. It will survey the sky in the energy range from 20 MeV to 300 GeV. The detector subsystem of the LAT will provide much better angular and energy resolution, effective area and field of view for gamma rays with respect to previous instruments. We present the LAT integration status, tests data taking and its scientific objectives together with the description of science tools preparation

[en] GLAST is the next generation telescope for the study of the Gamma Ray Universe. The GLAST mission is composed of two instruments: the LAT (Large Area Telescope) exploring the energy range between 20 MeV and 300 GeV and the GBM (Gamma ray Burst Monitor) studying the region from 10 KeV up to 30 MeV.GLAST represents an important step beyond EGRET providing a large improvement in instrument performance: large Field of View (FOV), large energy range extending to unexplored region of energies larger than 10 GeV, large effective area, a factor of 30 improvement in sensitivity, a much smaller dead time and a very good Point Spread Function (PSF).Since GLAST will operate in a continuous scanning mode, for most of the time during the mission, photons from a source will be detected at different angles in the LAT field of view requiring a good PSF in order to disentangle between sources.We will present results on PSF studies performed with various sets of data. The selection criteria and algorithm have been initially developed on DC1 and DC2 data (simulation of one and 55 days respectively of data collected by the LAT), applied to the data collected with the 16 LAT towers during the I and T integration phase with cosmic ray muons and finally applied to the testbeam data collected in August 2006 at the CERN beam line

[en] A detailed study has been made of the feasibility of Moeller scattering as a method for continuous monitoring of the LEP beam energy at high energies where the currently used resonant depolarisation technique may be unusable. Two methods, based on Moeller scattering, to measure the energy with different dominant systematic errors are discussed. Monte Carlo studies of the effect on the energy measurement of radiative corrections, target binding effects, beam parameters and calorimetric energy resolution have been made. It is shown how the beam parameters necessary to control the systematic error may be deduced from the Moeller scattering events, and the crucial target-detector distance monitored using ep scattering events. The beam energy precision is expected to be a few MeV at 90 GeV. The reduction of the systematic error on the W-mass measurement can be appreciable, and for a fixed total error on the W-mass may provide a considerable economy in running time at LEP2. The method is also applicable to precise energy measurement at high-energy electron linear colliders. (orig.)

[en] The Gamma-ray Large Area Space Telescope represents a great advance in space application of silicon detectors. With a surface of 80 m² and about 1 M readout channels it is the largest silicon tracker ever built for a space experiment. GLAST is an astro-particle mission that will study the mostly unexplored, high energy (20 MeV-300 GeV) spectrum coming from active sources or diffused in the Universe. The detector integration and test phase is complete. The full instrument underwent environmental testing and the spacecraft integration phase has just started: the launch is foreseen in late 2007. In the meanwhile the spare modules are being used for instrument calibration and performance verification employing the CERN accelerator complex. A Calibration Unit has been exposed to photon, electron and hadron beams from a few GeV up to 300 GeV. We report on the status of the instrument and on the calibration campaign.

[en] The calibration strategy of the GLAST Large Area Telescope (LAT) combines analysis of cosmic ray data with accelerator particle beams measurements. An advanced Monte Carlo simulation of the LAT, based on the Geant4 package, was set up to reproduce the LAT response to such radiation and to benchmark the event reconstruction and the background rejection strategy before launch and during operation. To validate the LAT simulation, a massive campaign of beam tests was performed between July and November 2006, in parallel with the LAT integration and test, on the LAT Calibration Unit. This is a detector built with spare flight modules and flight-like readout electronics, which was exposed to a large variety of beams, representing the whole spectrum of the signal that will be detected by the LAT, using the CERN and the GSI accelerator facilities. Beams of photons (0 - 2.5 GeV), electrons (1 - 300 GeV), hadrons (p and p, a few GeV - 100 GeV) and ions (C Xe, 1.5 GeV/n) were shot through the CU to measure the physical processes taking place in the detector and eventually fine-tune their description in the LAT Monte Carlo simulation. This paper describes the motivations and goals of the test runs, the many different experimental setups used, the measured detector performance and preliminary results of the LAT Monte Carlo validation

[en] The new facility SuperKEKB will be an upgrade of the existing KEKB electron–positron asymmetric collider, with a target luminosity of $8\times {10}^{35}{\mathrm{cm}}^{-2}{\mathrm{s}}^{-1}$, about 40 times greater than that of KEKB. The detector will also be upgraded to cope with the higher luminosity, pile-up and occupancy. We report here on the design and development of the new pure CsI calorimeter for the forward region. An intensive R&D is being carried on to study the performance of pure CsI crystals with Avalanche Photodiodes readout. Results about the relative energy resolution of this detector, along with radiation hardness studies of all the components, are presented. A matrix of 16 crystals has been put on an electron beam at the BTF facility in Frascati and results in terms of energy resolution of this prototype are also discussed.

[en] Renewable energy sources are becoming more and more important for energetic demand management across the world. The EU directive 2001/77/CE, indicated that the organic fraction of the municipal solid waste has a biogenic origin and so it can be assimilate to a biomass. Therefore the recovery of this fraction for energy production became important from both environmental (Kyoto Protocol) and economic point of view (green certificates). This paper propose a model to revamp MBT plants (two fluxes) to recover the organic fraction of MSW (OFMSW) that, at present, is converted into CO₂ and into low-quality compost which is finally disposed of in landfills. Here we propose that bio drying replaces bio stabilization allowing OFMSW to be used to produce energy
