We give direct experimental evidence for the observation of full transverse self-modulation a long, relativistic proton bunch propagating through dense plasma. The exits plasma with periodic density modulation resulting from radial wakefield effects. show that is seeded by ionization front created using an intense laser pulse copropagating bunch. extends over length following seed point. By varying one order magnitude, we frequency scales expected dependence on density, i.e., it equal to...
The seeded self-modulation of a relativistic, charged particle bunch in plasma is shown to grow both along the and plasma, resulting transverse wakefield amplitudes that far exceed initial seed values.
AWAKE is a proton-driven plasma wakefield acceleration experiment. % We show that the experimental setup briefly described here ready for systematic study of seeded self-modulation 400\,GeV proton bunch in 10\,m-long rubidium with density adjustable from 1 to 10$\times10^{14}$\,cm$^{-3}$. short laser pulse used ionization vapor propagates all way along column, suggesting full vapor. occurs bunch, at time and follows affects bunch.
Research on innovative technological methods in SMEs’ production processes is progressively receiving attention. However, little known about the emerging phenomenon of additive manufacturing (AM), which may represent a significant strategic lever for fostering company’s competitiveness and performance, especially SMEs. Our aim to investigate effects AM process, order better understand relative outcomes such an technique. We used latent content analysis empirically analyzing SMEs present one...
Social entrepreneurship is one of the most discussed issues in recent management literature. In partcular, social has recently gained atenton scholars interested understanding its sociological and anthropological aspects. This paper focuses on Claude Lévi-Strauss's noton "bricolage" way it can represent a signifcant opportunity to address emergent needs. Building postmodernist philosophical perspectve, namely Jacques Derrida's "deconstructonism," we atempt unpack bricolage phenomenon within...
The longitudinal density monitor (LDM) is primarily intended for the measurement of particle population in nominally empty rf buckets. These so-called satellite or ghost bunches can cause problems machine protection as well influencing luminosity calibration LHC. high dynamic range system allows with little 0.01% main bunch at same time characterization bunches. LDM a single-photon counting using visible synchrotron light. photon detector silicon avalanche photodiode operated Geiger mode,...
The transverse impedance in the LHC is expected to be dominated by numerous collimators, most of which are made Fibre-Reinforced-Carbon withstand impacts high intensity proton beams case failures, and will moved very close beam, with full gaps few millimetres, order protect surrounding super-conducting equipments. We present an estimate resistive-wall total at injection top energy, induced coupled-bunch growth rates tune shifts, finally result comparison theoretical predictions measurements...
A base band tune (BBQ) measurement system has recently been developed at CERN based on a high- sensitivity direct-diode detection technique followed by high resolution FFT algorithm implemented in an FPGA. The FPGA digital processing allows the acquisition of continuous real-time spectra with 32-bit resolution, while frequency synthesiser (DFS) can provide synchronised chirp excitation. All algorithms support dynamic reconfiguration and excitation parameters. Results from both laboratory...
The purpose of this paper is to understand the transition from technological innovation social by analysing insights biomedical context. Specifically, study investigates how entrepreneurs manage such a focusing on their motivations and awareness about innovation. adopts qualitative approach, in form multiple case studies Italian firms that produce use 3D printing field. Data was collected through in-depth interviews with entrepreneurs, backed available documentary evidence observation. This...
The accelerator control systems at CERN will be upgraded and many electronics modules such as analog digital I/O, level converters repeaters, serial links timing are being redesigned. new developments based on the FPGA Mezzanine Card, PCI Express VME64x standards while Wishbone specification is used a system chip bus. To attract partners, projects developed in an `Open' fashion. Within this Open Hardware project ways of working with industry evaluated it has been proven that can involved all...
The Giga Bit Transceiver based Expandable Front-End (GEFE) is a multi-purpose FPGA-based radiation tolerant card. It foreseen to be the new standard FMC carrier for digital front-end applications in CERN BE-BI group. Its intended use ranges from fast data acquisition systems slow control installed close beamlines, radioactive environment exposed total ionizing doses of up 750 Gy. This paper introduces architecture GEFE, its features as well examples application different setups.
The Beam Instrumentation Group (BI) is responsible for designing, building and maintaining the instrumen ts that allow observation of particle beams measurement related parameters all CERN accelerators transfer lines. This contribution aimed to give an overview ongoing electronic developments within beam instrumentation group both improve performances ease maintenance in existing machines meet requirements future accelerators. Details on some challenges proposed technical solutions will be presented.
<p>This paper builds on traditional and recent marketing research concerning the constituents of brand authenticity, particularly investigating consumers’ experience in context fashion industry. Specifically, we attempt to unpack dimensions underlying concept authenticity by, first, correlating role heritage ‘mythopoesis’ – creation a myth through repetitive narrative and, second, by applying our proposed theoretical framework four Italian luxury brands, namely Gucci, Salvatore...
