Abstract	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. Several recent instrumental advances are also presented, such as the development of total-energy detectors with $\gamma$ -ray imaging capability for background suppression, and the development of an array of small-volume organic scintillators aimed at exploiting the high instantaneous neutron-flux of EAR2. Finally, astrophysics prospects related to the intermediate $i$ neutron-capture process of nucleosynthesis are discussed in the context of the new NEAR activation area.

$Maxwellian averaged neutron-capture cross section at $kT=30$~keV (top panel) and their relative uncertainties (bottom panel). Blue colors refer to nuclei with neutron-shell closures and branching nuclei are displayed in red. Most values are taken from \cite{kadonisv1} (see text for details).$ $(Top panel) MC simulation~\cite{Zugec14} of the neutron sensitivity, which shows the C$_6$D$_6$-response to neutron-induced $\gamma$-ray background in the walls of the experimental hall. In practice, the resonant structure in the 1~keV-100~keV neutron-energy range is suppressed due to the loss of time-energy correlations for the scattered neutrons (see Ref.~\cite{Zugec16} for details). (Bottom panel) Capture yield of $^{93}$Zr($n,\gamma$)~\cite{Tagliente13}, which shows the limiting effect of the background level in the keV neutron-energy range.$ $Photograph of the i-TED array during a calibration measurement for the $^{79}$Se($n,\gamma$) experiment in 2022 at CERN n\_TOF EAR1.$ Show more plots
