n + $^7$Be Cross-Sections of Astrophysical Interest at the CERN n_TOF Facility / Mastromarco, Mario (CERN ; Manchester U.) ; Damone, Lucia Anna (INFN, Bari ; Bari U.) ; Barbagallo, Massimo (CERN ; INFN, Bari) /n_TOF Collaboration
One of the possible explanations of the so-called Cosmological Lithium Problem (CLIP), i.e., the large overestimate of the primordial$^7$Li abundance by the standard Big Bang Nucleosynthesis theory (BBN), is related to an incorrect underestimation of the 7 Be destruction rate by neutron-induced reactions. To verify this possibility, the n + $^7$Be reactions have been investigated at n_TOF (CERN) in a wide neutron energy range, taking advantage of the new high-flux experimental area (EAR2) and specifically developed experimental setups.

Review and new concepts for neutron-capture measurements of astrophysical interest / n_TOF Collaboration
The idea of slow-neutron capture nucleosynthesis formulated in 1957 triggered a tremendous experimental effort in different laboratories worldwide to measure the relevant nuclear physics input quantities, namely ($n,\gamma$) cross sections over the stellar temperature range (from few eV up to several hundred keV) for most of the isotopes involved from Fe up to Bi.

Measurement of the radiative capture cross section of the s-process branching points $^{204}$Tl and $^{171}$Tm at the n_TOF facility (CERN) / Casanovas, A (Barcelona, Polytechnic U.) ; Domingo-Pardo, C (Valencia U., IFIC) ; Guerrero, C (Seville U.) ; Lerendegui-Marco, J (Seville U.) ; Calviño, F (Barcelona, Polytechnic U.) ; Tarifeño-Saldivia, A (Barcelona, Polytechnic U.) ; Dressler, R (PSI, Villigen) ; Heinitz, S (PSI, Villigen) ; Kivel, N (PSI, Villigen) ; Quesada, J M (Seville U.) et al.
The neutron capture cross section of some unstable nuclei is especially relevant for s-process nucleosynthesis studies. This magnitude is crucial to determine the local abundance pattern, which can yield valuable information of the s-process stellar environment. [...]

$^7$Be(n,p) cross section measurement for the Cosmological Lithium Problem at the n_TOF facility at CERN / Anna, Damone Lucia (INFN, Bari) ; Colonna, N (INFN, Bari) ; Barbagallo, M (INFN, Bari ; CERN) ; Mastromarco, M (INFN, Bari) ; Andrzejewski, J (Lodz U.) ; Finocchiaro, P (INFN, LNS) ; Cosentino, L (INFN, LNS) /n_TOF
One of the most puzzling problems in Nuclear Astrophysics is the "Cosmological Lithium Problem", i.e the discrepancy between the primordial abundance of $^7$Li observed in metal poor halo stars [1], and the one predicted by Big Bang Nucleosynthesis (BBN). One of the reactions that could have an impact on the problem is $^7$Be(n,p)$^7$Li. [...]

Nuclear Astrophysics at n_TOF facility, CERN / Tagliente, G ; Aberle, O ; Alcayne, V ; Andrzejewski, J ; Audouin, L ; Babiano-Suarez, V ; Bacak, M ; Barbagallo, M ; Bécares, V ; Benedikt, Th et al. /n_TOF
CERN's neutron time-of-flight facility n_TOF has produced a considerable amount of experimental data since it has become fully operational with the start of its scientific measurement programme in 2001. The innovative features of the facility, in the two experimental areas, (flight paths 20 m and 185 m), allow for an accurate determination of the neutron cross section for radioactive samples or for isotopes with small neutron capture cross section, of interest for Nuclear Astrophysics.

Research and Development of a Scintillating Fiber Tracker with SiPM Array Read-Out for Application in Space / Perrina, Chiara (Geneva U.) ; Azzarello, Philipp (Geneva U.) ; Cadoux, Franck (Geneva U.) ; Marra, Daniel (Geneva U.) ; Wu, Xin (Geneva U.)
Scintillating fibers read-out by arrays of silicon photomultipliers can be complementary to silicon strip detectors for particle trackers in space or represent a viable alternative. Less fragile, more flexible, with no need of wire bonds, they can be used in high resolution charged particle tracking detectors for spaceborne experiments. [...]

The main characteristics of a large cryostat constructed by the gravitational wave group of the University of Rome, to cool down to liquid helium temperature Weber-type gravitational wave antennas, 3 m long and weighing up to 5000 kg, are presented. The cryogenic system has the following features: continuous operation time with an interval of 1 day every 54 days to refill the cryostat; small temperature gradients in the experimental chamber where the antenna is located, and very high acoustic and seismic insulation giving attenuation of 250 dB at the antenna detection frequency of 900 Hz.
