Measurement of the 240Pu(n,f) cross-section at the CERN n-TOF facility: First results from experimental area II (EAR-2)
(EDP Sciences, 2017)
The accurate knowledge of the neutron-induced fission cross-sections of actinides and other isotopes involved in the nuclear fuel cycle is essential for the design of advanced nuclear systems, such as Generation-IV nuclear ...

Performance of the reconstruction algorithms of the FIRST experiment pixel sensors vertex detector
(Elsevier, 2014)
Hadrontherapy treatments use charged particles (e.g. protons and carbon ions) to treat tumors. During a therapeutic treatment with carbon ions, the beam undergoes nuclear fragmentation processes giving rise to significant ...

Neutron capture on 94Zr: Resonance parameters and Maxwellian-averaged cross sections
(American Physical Society, 2011)
The neutron capture cross sections of the Zr isotopes play an important role in nucleosynthesis studies. The s-process reaction flow between the Fe seed and the heavier isotopes passes through the neutron magic nucleus ...

Output factor determination for dose measurements in axial and perpendicular planes using a silicon strip detector
(American Physical Society, 2012-04-23)
In this work we present the output factor measurements of a clinical linear accelerator using a silicon strip detector coupled to a new system for complex radiation therapy treatment verification. The objective of these ...

Simultaneous measurement of neutron-induced capture and fission reactions at CERN
(Springer Verlag, 2012)
The measurement of the capture cross-section of fissile elements, of utmost importance for the design of innovative nuclear reactors and the management of nuclear waste, faces particular difficulties related to the γ-ray ...

Production yields of beta+ emitters for range verification in proton therapy
(EDP Sciences, 2020)
In-vivo Positron Emission Tomography (PET) range verification relies on the comparison of the measured and estimated activity distributions from β+ emitters induced by the proton beam on the most abundant elements in the ...

A compact fission detector for fission-tagging neutron capture experiments with radioactive fissile isotopes
(Elsevier, 2020)
In the measurement of neutron capture cross-sections of fissile isotopes, the fission channel is a source of background which can be removed efficiently using the so-called fission-tagging or fission-veto technique. For ...

GEANT4 simulation of the neutron background of the C6D6 set-up for capture studies at n_TOF
(Elsevier, 2014)
The neutron sensitivity of the C6D6 detector setup used at n-TOF facility for capture measurements has been studied by means of detailed GEANT4 simulations. A realistic software replica of the entire n-TOF experimental ...

Towards PET range verification in proton therapy: new cross sections for improved accuracy
(2023-04-24)
Proton therapy is a form of radiotherapy that allows maximizing the deposited dose inside the tumour while reducing the dose in the healthy tissues, thanks to its superior depth-dose distribution when compared against ...
