The EUROnu project has studied three possible options for future, high intensity neutrino oscillation facilities in Europe. first is a Super Beam, which the neutrinos come from decay of pions created by bombarding targets with 4 MW proton beam CERN High Power Superconducting Proton Linac. far detector this facility 500 kt MEMPHYS water Cherenkov, located Fr\'ejus tunnel. second Neutrino Factory, and beams storage ring. case 100 magnetized iron at baseline 2000 km. third option Beta beta...
An overview of the ongoing efforts in area thermal hydraulics modeling a Molten Salt Fast Reactor (MSFR) is presented. The MSFR employs flowing liquid fuel based on high temperature lithium fluoride salt. A molten salt flow can be considered many situations as an incompressible flow. However, several phenomena intrinsic to pose unique challenges (radiative heat transfer, volumetric source, strong neutronics feedbacks, etc.). To study some these and improve current Computational Fluid...
Showers produced by positive hadrons in the highly granular CALICE scintillator-steel analogue hadron calorimeter were studied. The experimental data collected at CERN and FNAL for single particles with initial momenta from 10 to 80 GeV/c. response resolution spatial characteristics of shower development proton- pion-induced showers test beam simulations using Geant4 version 9.6 are compared.
LPSC has been involved for several years in a challenging research and development program on the production of pulsed ions beams with high ionization efficiency primarily dedicated to radioactive ion beams. The generation magnetic field requires use helix techniques developed at Laboratoire National des Champs Magnétiques Intenses. As first approach, cusp structure chosen. 3D simulations were used define geometry helices. computer aided design mechanical parts performed was optimized...
Experimental studies have been developed on a new freeze plug concept for safety valves in facilities using molten salt. They are designed to allow the closure of an upstream circuit by solidifying salt section device and passively melt case loss electric power, thus releasing upper fluid. The working principle these cold designs relies control heat transfer balance inside device, which determines whether solidifies or melts. is mainly composed steel masses that dimensioned provide...

The innovations allowing to meet challenging requirements operation presented. system performance evaluated based on detector tests with a cosmic rays trigger standalone high rate validation tests. Finally, perspectives adapt or part it other experiments discussed.
``Beta beams'' produce collimated pure electron (anti)neutrino beams by accelerating beta active ions to high energies and having them decay in a racetrack shaped storage ring of 7 km circumference, the ring. EUROnu are based on CERN infrastructures existing machines. Using machines may be an advantage for cost evaluation, but will also constrain physics performance. The isotope pair choice beam is $^{6}\mathrm{He}$ $^{18}\mathrm{Ne}$. However, before studies one required isotopes,...
We present a study of showers initiated by electrons, pions, kaons, and protons with momenta from 15 GeV to 150 in the highly granular CALICE scintillator-tungsten analogue hadronic calorimeter. The data were recorded at CERN Super Proton Synchrotron 2011. analysis includes measurements calorimeter response each particle type as well energy resolution studies longitudinal radial shower development for selected particles. results are compared Geant4 simulations (version 9.6.p02). In we...
Recently, the possibility to use compact accelerators coupled high current ion sources for production of intense low energy proton or deuteron beams has motivated many research laboratories develop accelerator based neutrons several purposes, including Neutron Capture Therapy (NCT). The NCT needs a flux, about 10 9 n.cm -2 .s -1 , thermal (E<10 keV) at tumour site. Up now, required neutron flux was mainly delivered by nuclear reactors. However, such is now possible using on specific...
The steadily increasing luminosity of the LHC requires an upgrade with high-rate and high-resolution detector technology for inner end cap ATLAS muon spectrometer: New Small Wheels (NSW). In order to achieve goal precision tracking at a hit rate about 15 kHz/cm$^2$ radius NSW, large area Micromegas quadruplets 100\,\microns spatial resolution per plane have been produced. % IRFU, from CEA research center Saclay, is responsible production validation LM1 modules. construction, production,...
Target thermal capabilities are one of the major key points for CANS (Compact Accelerator-based Neutron Source) developments. Indeed, high energy (few MeV) and average current tens mA) proton or deuteron beams required to produce neutron flux 101³ ncm⁻2s⁻1 greater. The targets must therefore absorb dissipate a power. In order make progress on their designs without beams, we developed compact electron beamline based an Electron Cyclotron Resonance (ECR) source that permits testing under...

LPSC-Grenoble is involved R\&D activities for Large Detector (ILD) particular electromagnetic calorimeter (ECal): i.e. design fastening cooling systems, mechanics end-caps, test EM prototypes, tooling integration end-caps.
Objective. The design of neutron moderators for BNCT treatment units currently relies on parametric approaches, which yield quality results but are ultimately limited by human imagination. Efficient non-intuitive solutions may thus be missed out. This limitation needs to addressed.Approach. To overcome this limitation, we propose use a topology optimization algorithm coupled with state-of-the-art Monte-Carlo transport code. approach recently proved capable finding complex optimal...
