Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
During the commissioning of the CERN Proton Synchrotron multiturn extraction, tests with different beam intensities were performed in order to probe the behavior of resonance crossing in the presence of possible space charge effects. The initial beam inten ...
Par définition, un système de transfert d’énergie par induction (ou sans contacts) se passe de connexion matérielle entre la source d’énergie et le consommateur. Néanmoins et selon les cas, un transfert d’informations entre les deux parties peut être requi ...
Granular solid targets made of fluidised tungsten powder have been long proposed and are being studied as an alternative configuration towards high-power (>1MW beam power) target systems, suitable for a future Super Beam facility or Neutrino Factory. A fea ...
This report presents some approaches to modelize urban energy systems. More precisely, as a first step, a clear definition of what is an urban energy system model is exposed before listing the main tech- niques of modelization. With the goal to run a case ...
The CERN-LHC is a high energy particle collider, where intense proton bunches are brought into collision. In order to achieve optimum performance, the bunches must have a high brightness, leading to strong and significant beam-beam effects. Experimental te ...
In the first two years of operation of the CERN Large Hadron Collider (LHC), the betatron squeeze has been carried out at constant flat top energy of 3.5 TeV. Squeeze setting functions are separated from the energy ramp functions. This ensured a maximum fl ...
Recently, the LHC@home system has been revived at CERN. It is a volunteer computing system based on BOINC which allows boosting the available CPU-power in institutional computer centers by the help of individuals that donate the CPU-time of their PCs. Curr ...
Micro-channel cooling is gaining considerable attention as an alternative technique for cooling of High-Energy Physics (HEP) detectors and Front-End (FE) electronics. This technology is being evaluated for future tracking devices, where material budget lim ...
les accélérateurs de particules sont des installations conçues pour recevoir des particules à basse énergie et les accélérer avant extraction. ils fonctionnent généralement en mode pulsé, ce qui entraîne des variations de puissance très élevées et très rap ...
This PhD work is about limitations of high intensity proton beams observed in the CERN Proton Synchrotron (PS) and, in particular, about issues at injection and transition energies. With its 53 years, the CERN PS would have to operate beyond the limit of i ...
