We present the ICONE project which proposes to build a HiCANS source in France. The aim of is be able provide French neutron user community sufficient instrumental capacity continue performing scattering experiments for their research programs. baseline goal offer performances equivalent medium power reactor or spallation (such as Orphée ISIS). consider that such machine would fulfil needs at least two-thirds users not require ultimate but simply beam-time perform experiments. also describe...
Previous studies of the physics potential LEP2 indicated that with design luminosity 500 inverse picobarn one may get a direct measurement mass W-boson precision in range 30 - 50 MeV. This report presents an updated evaluation estimated error on based recent simulation work and improved theoretical input. The most efficient experimental methods which will be used are also described.
The construction and the assembly of two end-caps ATLAS liquid argon electromagnetic calorimeter as well their test qualification programs are described. work described here started at beginning 2001 lasted for approximately three years. results tests performed before installation in LHC pit given. detectors now installed cavern, full being commissioned. complete coverage is powered with high voltage readout.
A 2 m long prototype of a lead-liquid argon electromagnetic caloriemeter with accordion-shaped electrodes, conceived as sector the barrel calorimeter future ATLAS experiment at LHC, has been tested electron and pion beams in energy range 10 to 287 GeV. sampling term 10%√E(GeV) was obtained for electrons rapidly 0 < η 1, while constant measured over an area about 1 m2 is 0.69%.

There is a worldwide growing interest for small-scale and reduced-cost neutron sources not based on nuclear fission.High-intensity proton or deuteron beams impinging light materials could be used to produce such with intensities brightness comparable reactor dedicated experiments.To develop technologies several key technological issues have addressed.Among them the production maximization of extraction transport instrument parameter design high-brightness adapted required application.This...
A new type of Beam Loss Monitor (BLM) system is being developed for use in the European Spallation Source (ESS) linac, primarily aiming to cover low energy part (proton energies between 3-100 MeV). In this region typical BLM detectors based on charged particle detection (i.e. Ionization Cham-bers) are not appropriate because expected fields will be dominated by neutrons and photons. Another issue photon background due RF cavities, which mainly field emission from electrons cavity walls,...

These properties make suitable for electromagnetic calorimeter.
There is currently a big effort put into the operation and construction of world class neutron scattering facilities (SNS SNS-TS2 in US, J-PARC Japan, ESS Europe, CSS China, PIK Russia). On other hand, there exists network smaller which play key role creating large community who able to efficiently use existing facilities. With foreseen closure ageing nuclear research reactors, especially risk seeing shrinking thus reflection being conducted several countries for replacement reactors with...
Facilities providing bright thermal neutron beams are of primary importance for various research topics such as condensed matter experiments, neutron-imaging or medical applications. Currently these mainly spallation sources and nuclear reactors. However, later facilities ageing the political context does not favor building new ones. This is case in CEA-Saclay (France), where Orphee reactor planned to shutdown 2019. Therefore, another local facility, affordable by one country, able provide...
With the development of high-intensity accelerators, it is now envisaged to build compact neutron sources for various applications. At CEA Saclay, we have started a project promote such technology based on existing 100 mA IPHI proton injector. We are focusing our interest low-energy proton-induced reactions (less than 20 MeV) provide an economical way produce neutrons and also limit radiological constraints. Optimization studies target-moderator assembly require validated simulation tools in...
For next decade, the European neutron scattering community will face of important changes, as many facilities close, strictly fission-based sources. This statement mainly concerns France with planned closure Orphee and ILL. At CEA-Saclay, project SONATE has been launched in order to provide a high intensity source Saclay site, this is based on Compact Accelerator-driven Neutron Sources technology coupled high-intensity beams. The goal develop 50 kW target, aiming produce at least yield 1013...

Facilities providing bright thermal neutron beams are of primary importance for various research topics. At CEA-Saclay, a compact accelerator driven source, SONATE, is investigated in taking advantage the IPHI able to deliver 3 MeV proton beam with an intensity up 100 mA.
