The front-end electronics system for the CMS electromagnetic calorimeter
No full textCMS designed an high precision electromagnetic calorimeter, to be operated reliably in the high radiation environment of the CERN Large Hadron Collider (LHC), inside the 4 T magnetic field. Innovative solutions were developed to place the front-end electronics within the detector with the advantage of minimizing external noise, while reducing the number of optical links to send data to the off-detector readout. The final system architecture will be reviewed in detail. High resolution, over the wide energy dynamic range, was obtained with studies in an electron test beam
Muon Collider. A Path to the Future?
No full textA muon collider would be both a precision and a powerful discovery machine, because it can offer collisions of point-like particles at very high energies, strongly exceeding the energy reach of other lepton colliders. It can even match the discovery of a proton collider with much higher energy, since the muon collision energy is fully available at constituent level unlike for the protons. However, the need for high luminosity faces technical challenges which arise from the short muon lifetime at rest and the difficulty of producing large numbers of muons in bunches with small emittance. Addressing these challenges requires the development of innovative concepts and demanding technologies. In view of the potential importance of muon colliders for the future of high-energy physics it is timely to start an R&D; programme now.A high-energy muon collider is receiving renewed attention as a possible frontier-exploration machine. Daniel Schulte, Nadia Pastrone and Ken Long describe the possible paths ahead
The study of ancient archaeological finds through X-ray tomography: the case of the “Tintinnabulum” from the Museum of Anthropology and Ethnography of Torino.
No full textX-ray Computed Tomography (CT) is a widely used diagnostic technique in the field of Cultural Heritage and beyond, above all thanks to its non invasiveness. The high penetrating power of X-rays allows us to investigate the internal structure of the analysed objects, thus obtaining valuable information related to the history of artistic and archaeological finds. In particular, CT provides useful data on the entire volume of the objects, to finally obtain a 3D model of the studied artworks. In this field, the goal of the “neu_ART” project, a collaboration among different institutions in Torino funded by Regione Piemonte in 2010, was to develop radio-tomographic set-ups for X-ray imaging analysis dedicated to Cultural Heritage studies. In this paper, a computed tomography investigation on an ancient ceramic rattle from the Museum of Anthropology and Ethnography of the University of Torino is presented. This is the first analysis carried out at the Physics Department of University of Torino, using the imaging set-up based on a TDI linear detector moved by a high precision mechanical system. Thanks to this study, much information on the technique of execution and the state of conservation was obtained
La Forza Nascosta | The Hidden Force
No full textEnglish follows***Al completo***La Forza NascostaScienziate nella Fisica e nella StoriaLo spettacolo offre una visuale sulla Fisica del '900 attraverso gli occhi di quattro sue protagoniste solo in parte riconosciute: l'astronoma americana Vera Cooper Rubin, la fisica nucleare austriaca Marietta Blau, la fisica delle particelle cinese Chien-Shiung Wu e l'italiana Milla Baldo Ceolin. Le loro vite si sono svolte in un contesto internazionale caratterizzato da grandi sconvolgimenti, ma anche dalla nascita della Fisica moderna e di istituzioni come il CERN.Conosceremo quattro donne iconiche che hanno amato la Scienza, quattro come le forze della Natura: la forza di Gravità, Elettromagnetica, Debole e Forte. Ma c'è un'altra forza nascosta che ogni spettatore percepirà, ed è la forza delle donne, che genera una spinta verso la Scienza come luogo di rispetto, progresso e civile convivenza.La Forza Nascosta è stato ideato, scritto e promosso da un gruppo di fisiche donne della Sezione di Torino dell'Istituto Nazionale di Fisica Nucleare, Anna Ceresole, Nora De Marco e Nadia Pastrone, e dal Dipartimento di Fisica dell'Università di Torino, Simonetta Marcello, insieme alla storica delle Donne Emiliana Losma, esperta di nuove tecnologie Rita Spada, l'autrice e regista Gabriella Bordin, l'autrice, attrice e attivista Elena Ruzza, in collaborazione con la soprano Fé Avouglan. Ingresso gratuito con registrazione obbligatoria | Evento in italiano con sottotitoli in inglese.***Fully booked***The Hidden ForceWomen in Physics and HistoryThe play offers a view of twentieth century’s Physics through the eyes of four only partly credited protagonists: American astronomer Vera Cooper Rubin, Austrian nuclear physicist Marietta Blau, Chinese particle physicist Chien Shung Wu and Italian Milla Baldo Ceolin. Their lives unwound in an international context characterised by great upheaval, but also by the birth of modern Physics and of institutions like CERN. We shall meet four iconic women who have loved Science, four like the forces of Nature: the force of Gravity, Electromagnetic, Weak and Strong. But there is another hidden force that any spectator will perceive, and it is the force of women, generating a drive towards Science as a place of respect, progress and civil coexistence.The Hidden Force was conceived, written and promoted by a group of women physicists from the Turin Division of the National Institute of Nuclear Physics, Anna Ceresole, Nora De Marco and Nadia Pastrone, and from the Physics Department of the University of Turin, Simonetta Marcello, together with Women’s historian Emiliana Losma, expert in new technologies Rita Spada, author and director Gabriella Bordin, author, actress and activist Elena Ruzza, in collaboration with soprano Fé Avouglan.

A Flexible Tool for Beam Induced Background Simulations at a Muon Collider
No full textA Muon Collider represents a very interesting possibility for a future machine to explore the energy frontier in particle physics.However, to reach the needed luminosity, beam intensities of the order of muons per bunch are needed. In this context, the Beam Induced Background must be taken into account for its effects on the magnets and on the detector. Several optimizations can be conceived with the aim to mitigate them. In this view, it is of crucial importance to develop a flexible tool that allows to easily reconstruct the machine geometry in a Monte Carlo code, allowing to simulate in detail the interaction of muon decay products in the machine, while being able to change the machine optics itself to find the best configuration.In this contribution, a possible approach to such a purpose is presented, based on FLUKA for the Monte Carlo simulation and on LineBuilder for the geometry reconstruction.First results for the 1.5TeV machine optics developed by the MAP collaboration are discussed in this paper
