Segment-averaged LET concept and analytical calculation from microdosimetric quantities in proton radiation therapy
(Wiley, 2019)
Purpose: This work introduces the concept of segment-averaged linear energy transfer (LET) as a new approach to average distributions of LET of proton beams based on a revisiting of microdosimetry theory. The concept of ...

First Measurement of 72Ge(n,γ) at n_TOF
(EDP Sciences: EPJ Open Access, 2018)
The slow neutron capture process (s-process) is responsible for producing about half of the elemental abundances heavier than iron in the universo.

Constraints on the dipole photon strength for the odd uranium isotopes
(American Physical Society, 2022)
Background: The photon strength functions (PSFs) and nuclear level density (NLD) are key ingredients for calculation of the photon interaction with nuclei, in particular the reaction cross sections. These cross sections ...

Measurement of the 70Ge(n,γ) cross section up to 300 keV at the CERN n_TOF facility
(American Physical Society, 2019)
Neutron capture data on intermediate mass nuclei are of key importance to nucleosynthesis in the weak component of the slow neutron capture processes, which occurs in massive stars. The (n,γ) cross section on 70Ge, which ...

238U(n, γ) reaction cross section measurement with C6D6 detectors at the n_TOF CERN facility
(EDP Sciences, 2014)
The radiative capture cross section of 238U is very important for the developing of new reactor technologies and the safety of existing ones. Here the preliminary results of the 238U(n,γ) cross section measurement performed ...

Fission program at n_TOF
(EDP Sciences, 2019)
Since its start in 2001 the n_TOF collaboration developed a measurement program on fission, in view of advanced fuels in new generation reactors. A special effort was made on measurement of cross sections of actinides, ...

Measurement of the angular distribution of fission fragments using a PPAC assembly at CERN n-TOF
(Elsevier, 2014)
A fission reaction chamber based on Parallel Plate Avalanche Counters (PPACs) was built for measuring angular distributions of fragments emitted in neutron-induced fission of actinides at the neutron beam available at the ...

Measurement of fragmentation cross sections of 12C ions on a thin gold target with the FIRST apparatus
(American Physical Society, 2016)
A detailed knowledge of the light ions interaction processes with matter is of great interest in basic and applied physics. As an example, particle therapy and space radioprotection require highly accurate fragmentation ...

Measurement of the α ratio and (n, γ) cross section of 235U from 0.2 to 200 eV at n_TOF
(American Physical Society, 2020)
We measured the neutron capture-to-fission cross-section ratio (α ratio) and the capture cross section of 235U between 0.2 and 200 eV at the n_TOF facility at CERN. The simultaneous measurement of neutron-induced capture ...
