    The LHCb upgrade I

    The LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger than that of the previous running periods. Readout of all detectors into an all-software trigger is central to the new design, facilitating the reconstruction of events at the maximum LHC interaction rate, and their selection in real time. The experiment's tracking system has been completely upgraded with a new pixel vertex detector, a silicon tracker upstream of the dipole magnet and three scintillating fibre tracking stations downstream of the magnet. The whole photon detection system of the RICH detectors has been renewed and the readout electronics of the calorimeter and muon systems have been fully overhauled. The first stage of the all-software trigger is implemented on a GPU farm. The output of the trigger provides a combination of totally reconstructed physics objects, such as tracks and vertices, ready for final analysis, and of entire events which need further offline reprocessing. This scheme required a complete revision of the computing model and rewriting of the experiment's software

    National audienceL'étude de l'insertion professionnelle des ingénieurs provenant des écoles d'agriculture et d'agro-alimentaire s'appuie sur les bases de données éditées par les associations des anciens élèves de différentes écoles : l'ENSBANA de Dijon, l'ISA de Lille et l'ISARA de Lyon. L'influence de l'école dans la zone géographique de son implantation repose à la fois sur l'insertion professionnelle des ingénieurs dans la région, sur la politique de recherche de l'école et sur sa stratégie locale. Les ingénieurs formés par l'ENSBANA, l'ISA et l'ISARA ne se répartissent pas uniformément sur le territoire français. Certaines régions semblent plus attractives que d'autres. Le caractère régional est particulièrement marqué pour l'ISA et l'ISARA, tandis que l'ENSBANA exprime davantage un caractère national. Ces observations se vérifient dans le temps, l'ISARA étendant son influence aux départements limitrophes (le Sud-Est) et l'ENSBANA renforçant son implantation nationale. Sur les 3 053 individus composant l'échantillon, 705 (23,1%) exercent dans le secteur de l'agro-alimentaire. Plus de la moitié sont des ingénieurs ESBANA. Les ingénieurs ISARA ou ISA quant à eux trouvent un emploi hors de l'agro-alimentaire pour 85% d'entre eux

    Abstract The LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger than that of the previous running periods. Readout of all detectors into an all-software trigger is central to the new design, facilitating the reconstruction of events at the maximum LHC interaction rate, and their selection in real time. The experiment's tracking system has been completely upgraded with a new pixel vertex detector, a silicon tracker upstream of the dipole magnet and three scintillating fibre tracking stations downstream of the magnet. The whole photon detection system of the RICH detectors has been renewed and the readout electronics of the calorimeter and muon systems have been fully overhauled. The first stage of the all-software trigger is implemented on a GPU farm. The output of the trigger provides a combination of totally reconstructed physics objects, such as tracks and vertices, ready for final analysis, and of entire events which need further offline reprocessing. This scheme required a complete revision of the computing model and rewriting of the experiment's software.</jats:p
