The CMS drift tubes (DT) muon detector, built for withstanding the LHC expected integrated and instantaneous luminosities, will be used also in the High Luminosity LHC (HL-LHC) at a 5 times larger instantaneous luminosity and, consequently, much higher levels of radiation, reaching about 10 times the LHC integrated luminosity. Initial irradiation tests of a spare DT chamber at the CERN gamma irradiation facility (GIF++), at large ($\sim$O(100)) acceleration factor, showed ageing effects resulting in a degradation of the DT cell performance.

Irradiation aging of the CMS Drift Tube muon detector / Ferrero, D.D. Redondo ; Abbiendi, G. ; Maestre, J. Alcaraz ; Fernández, A. Álvarez ; González, B. Álvarez ; Amapane, N. ; Bachiller, I. ; Barcala, J.M. ; Barcellan, L. ; Battilana, C. et al.
During the High Luminosity LHC, the Drift Tube chambers installed in the CMS detector need to operate with an integrated dose ten times higher than expected at the LHC due to the increase in integrated luminosity from 300 fb${-1}$ to 3000 fb$^{-1}$. Irradiations have been performed to assess the performance of the detector under such conditions and to characterize the radiation aging of the detector. [...]

A Segmented Total Energy Detector (sTED) optimized for $(n,\gamma)$ cross-section measurements at n_TOF EAR2 / n_TOF Collaboration
The neutron time-of-flight facility n_TOF at CERN is a spallation source dedicated to measurements of neutron-induced reaction cross-sections of interest in nuclear technologies, astrophysics, and other applications. Since 2014, Experimental ARea 2 (EAR2) is operational and delivers a neutron fluence of $4\times 10^7$ neutrons per nominal proton pulse, which is 50 times higher than the one of Experimental ARea 1 (EAR1) of $8\times10^5$ neutrons per pulse.

First measurement of the $^{94}$Nb($n$,$\gamma$) cross section at the CERN n_TOF facility / n_TOF Collaboration
One of the crucial ingredients for the improvement of stellar models is the accurate knowledge of neutron capture cross-sections for the different isotopes involved in the $s$-,$r$- and $i$- processes. These measurements can shed light on existing discrepancies between observed and predicted isotopic abundances and help to constrain the physical conditions where these reactions take place along different stages of stellar evolution.In the particular case of the radioactive $^{94}$Nb, the $^{94}$Nb($n$,$\gamma$) cross-section could play a role in the determination of the $s$-process production of $^{94}$Mo in AGB stars, which presently cannot be reproduced by state-of-the-art stellar models.

Recent highlights and prospects on (n,$\gamma$) measurements at the CERN n_TOF facility / n_TOF Collaboration
Neutron capture cross-section measurements are fundamental in the study of the slow neutron capture (s-) process of nucleosynthesis and for the development of innovative nuclear technologies. [...]

Advances and new ideas for neutron-capture astrophysics experiments at CERN n_TOF / n_TOF Collaboration
This article presents a few selected developments and future ideas related to the measurement of $(n,\gamma)$ data of astrophysical interest at CERN n_TOF. The MC-aided analysis methodology for the use of low-efficiency radiation detectors in time-of-flight neutron-capture measurements is discussed, with particular emphasis on the systematic accuracy.

Search for dijet resonances using events with three jets in proton-proton collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
A search for a narrow resonance with a mass between 350 and 700 GeV, and decaying into a pair of jets, is performed using proton-proton collision events containing at least three jets. The data sample corresponds to an integrated luminosity of 18.3 fb$^{-1}$ recorded at $\sqrt{s} =$ 13 TeV with the CMS detector. [...]

Measurement of the azimuthal anisotropy of $\Upsilon$(1S) and $\Upsilon$(2S) mesons in PbPb collisions at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV / CMS Collaboration
The second-order Fourier coefficients (${v_{2}} $) characterizing the azimuthal distribution of $\Upsilon(\text{1S})$ and $\Upsilon(\text{2S})$ mesons arising from PbPb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} =$ 5.02 TeV are studied. The $\Upsilon$ mesons are reconstructed in their dimuon decay channel, as measured by the CMS detector. [...]

Challenging neutron-capture cross-section measurements of small cross sections and samples with a very limited number of atoms require high-flux time-of-flight facilities. In turn, such facilities need innovative detection setups that are fast, have low sensitivity to neutrons, can quickly recover from the so-called $\gamma$-flash, and offer the highest possible detection sensitivity.
