23. Behaviour of uranium dioxide under irradiation: combined effects of radiation defects induced by ballistic and electronic excitation

Mme Marion Bricout (CEA Saclay)

29/05/2018 16:15

Poster

During in-reactor operation, the nuclear fuel is subjected to simultaneous radiation sources induced by the slowing down of fission fragments, the alpha and beta decay, etc. In addition, fission products incorporation induce chemical effects in the matrix. At the atomic scale radiation, damage is produced by both low-energy particles, leading to the collision cascades formation and high-energy...

46. Characterising turbulence in large scale structures with X-ray satellites.

M. Edouard Lecoq (Institut d'Astrophysique Spatiale)

29/05/2018 16:15

Poster

Understanding the baryonic processes taking place in the large scale structures of the Universe is essential both if we want to understand structure formation and the biases they may induce in cosmological studies (e.g. σ8 or ωm). Among those processes, turbulent motions that are induced at various scales, for instance by AGN jets or accretion of matter from intergalactic filaments, are...

30. Combining experimental and computational approaches for the understanding of the basic mechanisms of irradiation-defect formation and evolution

M. Xin Jin (CSNSM, CNRS)

29/05/2018 16:15

Poster

Ion beams are currently used in numerous fields of material science. It is crucial to have powerful tools to characterize irradiated materials and to have a better understanding of the basic mechanisms of the ion/solid interactions through mastering the technical aspects of the use of ion beams.
The aim of the thesis work is to develop new approaches that combine experimental characterization...

42. Correction of electromagnetic showers shape in Monte-Carlo modelling of ATLAS calorimeter

Mykola Khandoga (CEA Saclay)

29/05/2018 16:15

Poster

The electromagnetic calorimeter is one of the key elements of the ATLAS detector at the Large Hadron Collider at CERN. In combination with the inner tracker the calorimeter allows to measure the energy and the momentum of electrons and photons coming out of the interaction point of the detector.
In order to properly reconstruct the physical processes happening after the collision it is...

32. Creation of clinical proton minibeams using magnetic focussing

M. Tim Schneider (IMNC - Université Paris-Sud)

29/05/2018 16:15

Poster

Minibeam radiation therapy (MBRT) is a promising cancer treatment method that can help increase the sparing of healthy tissue while simultaneously allowing for higher doses to be administered, thereby making new types of cancers (hypoxic tumors) accessible to this type of treatment. While MBRT with x-rays is already being put to use in hospitals, the advantages of irradiating with protons and...

43. Developments in the Spherical Proportional Counter for NEWS-G

M. Patrick Knights (CEA Saclay/IRFU)

29/05/2018 16:15

Poster

The NEWS-G collaboration utilises the novel technology of the Spherical Proportional Counter (SPC) to conduct a direct search for low mass Dark Matter (DM) candidates. The SPC comprises a grounded metallic spherical vessel with a central spherical readout anode. In the ideal geometry, the radial electric field within the detector varies as 1/r$^{2}$, however, the details of the support...

9. Implémentation parallèle hybride des simulations PIC en géométrie cylindrique avec décomposition de Fourier dans le code SMILEI

Mme Imen Zemzemi (Laboratoire Leprince-Ringuet)

29/05/2018 16:15

Poster

Les simulations Particle-in-Cell sont utilisées dans une large variété de problèmes liés à la physique des plasmas. Dans plusieurs cas, une description précise et fiable des effets cinétiques qui se produisent en 3D est requise. Néanmoins, ce type de simulations est très couteux et nécessite beaucoup de ressources de calcul. Ceci est principalement dû à la haute résolution que nécessite les...

11. Laser Plasma Acceleration Generated Electron Bunch Transport for in a Manipulation Line

M. Driss Oumbarek Espinos (Synchrotron SOLEIL)

29/05/2018 16:15

Poster

Laser Plasma Acceleration (LPA) enables to generate up to several GeV electron beam with short bunch length and high peak current within centimeters scale via different schemes. However, the generated beam quality (energy spread, divergence) is not sufficient to drive a Free Electron Laser (FEL) and a beam control is required. The COXINEL manipulation line is composed of high gradient variable...

12. Measurement of the top quark pole mass using double differential cross section with the ATLAS detector at the LHC

Mme Tetiana Moskalets (CEA/IRFU/DPhP)

29/05/2018 16:15

Poster

The top quark mass ($m_t$) is a key parameter of the Standard Model (SM). Its large size, of the order of the electroweak scale, is associated with a Yukawa coupling of order 1, that gives important contributions, via radiative corrections, to SM observables. After the Higgs boson discovery and the accurate measurement of its mass, the allowed values of the W boson and top quark masses have...

5. Naturalness of a brane-localized electroweak Higgs boson

M. Florian Nortier (Laboratoire de Physique Théorique d'Orsay)

29/05/2018 16:15

Poster

In the Standard Model (SM) of Particle Physics, the electroweak (EW) symmetry breaking pattern is the less known and understood. With the discovery of a Higgs-like boson by the Large Hadron Collider (LHC) experiment in 2012, the Brout-Englert-Higgs (BEH) mechanism, which involves a new scalar field to break the EW gauge symmetry, seems to be at work in Nature. Nevertheless, the origin of the...

31. Polarex, a future facility for on line nuclear orientation

M. Rémy Thoër

29/05/2018 16:15

Poster

Low temperature nuclear orientation (LTNO) allows to study polarized exotic nuclei. At very low temperature (~10mK) nuclei can experience a very high polarization in the hyperfine field which exists into a ferromagnetic metal host. The decay products can be observed using proton, alpha or beta-particle detectors fitted within the cryostat and/or external gamma or neutron detectors, providing a...

33. Study of beam-surface interactions and dynamic pressure generated by electron clouds and ions for the high luminosity upgrade of the LHC & the Future Circular Collider study

Mme Suheyla Bilgen (LAL)

29/05/2018 16:15

Poster

The High Luminosity LHC (HL-LHC) is an upgrade of the LHC to achieve instantaneous luminosities a factor of five larger than the LHC nominal value. The Future Circular Collider (FCC) study is developing designs for a higher performance particle collider to extend the research currently being conducted by present colliders. For these two project, the investigation of beam interactions with the...
