Vertically Aligned Carbon Nanotubes as Pixel Detector Substrate Open
Carbon Nano-Tubes (CNTs) posses extraordinary electrical conductivity, heat conductivity, mechanical and chemical properties. I propose in this paper the usage of VACNTs as the sensor substrate, or in the case of hybrid detectors, as a pix…

Machine-Induced Showers Entering the Atlas and CMS Detectors in the LHC Open
One source of experimental background in the LHC is showers induced by particles hitting the upstream collimators or particles that have been scattered on the residual gas. We estimate the flux and distribution of particles entering the AT…

Characterization of a hybrid pixel counting detector using a silicon sensor and the IBEX readout ASIC for electron detection Open
In this paper we report on the performance of a Hybrid Pixel Detector — consisting on an IBEX ASIC bump-bonded to a 450 μm-thick Silicon sensor with a pixel size of 75 μm — used as a direct electron detector up to 300 keV. The count homoge…

Measurement of the <sup>241</sup>Am neutron capture cross section at the n_TOF facility at CERN Open
New neutron cross section measurements of minor actinides have been performed recently in order to reduce the uncertainties in the evaluated data, which is important for the design of advanced nuclear reactors and, in particular, for deter…

High accuracy <sup>234</sup>U(n,f) cross section in the resonance energy region Open
New results are presented of the 234U neutron-induced fission cross section, obtained with high accuracy in the resonance region by means of two methods using the 235U(n,f) as reference. The recent evaluation of the 235U(n,f) obtained with…

Measurement of the neutron capture cross section of the fissile isotope <sup>235</sup>U with the CERN n_TOF total absorption calorimeter and a fission tagging based on micromegas detectors Open
The accuracy on neutron capture cross section of fissile isotopes must be improved for the design of future nuclear systems such as Gen-IV reactors and Accelerator Driven Systems. The High Priority Request List of the Nuclear Energy Agency…

High precision measurement of the radiative capture cross section of<sup>238</sup>U at the n_TOF CERN facility Open
The importance of improving the accuracy on the capture cross-section of 238U has been addressed by the Nuclear Energy Agency, since its uncertainty significantly affects the uncertainties of key design parameters for both fast and thermal…

Dissemination of data measured at the CERN n_TOF facility Open
The n_TOF neutron time-of-flight facility at CERN is used for high quality nuclear data measurements from thermal energy up to hundreds of MeV. In line with the CERN open data policy, the n_TOF Collaboration takes actions to preserve its u…

Experiments with neutron beams for the astrophysical<i>s</i>process Open
Neutron capture cross sections are the key nuclear physics input to study the slow neutron capture process, which is responsible for forming about half of the elemental abundances above Fe. Stellar neutron capture cross section can be meas…

Towards the high-accuracy determination of the<sup>238</sup>U fission cross section at the threshold region at CERN – n_TOF Open
The 238U fission cross section is an international standard beyond 2 MeV where the fission plateau starts. However, due to its importance in fission reactors, this cross-section should be very accurately known also in the threshold region …

Fission Fragment Angular Distribution measurements of<sup>235</sup>U and<sup>238</sup>U at CERN n_TOF facility Open
Neutron-induced fission cross sections of 238U and 235U are used as standards in the fast neutron region up to 200 MeV. A high accuracy of the standards is relevant to experimentally determine other neutron reaction cross sections. Therefo…
