| contents | The quasistellar neutron spectrum produced via $^{7}$Li($p$, $n$)$^{7}$Be reaction at a proton energy of 1.912 MeV has been extensively studied and employed reaction for neutron-induced reaction studies. We are working towards using this reaction at various proton energies from 1.9 MeV to 3.6 MeV to produce a neutron field at a temperature range of $\sim$1.5-3.5 GK to conduct measurements of neutron-induced charge particle reaction cross sections on various unstable nuclei at explosive stellar temperatures. In this paper, we are reporting our design and simulation study with regards to experimental set-up and a gaseous detector with a segmented Micromegas detector for conducting neutron-induced charge particle reactions studies for nuclei of astrophysics importance, for example, $^{26}$Al($n$, $p$)$^{26}$Mg, $^{26}$Al($n$, $α$)$^{23}$Na and $^{40}$K($n$, $p$)$^{40}$Ar, $^{40}$K($n$, $α$)$^{37}$Cl reactions. We plan to perform our experiments with a 10-$μ$A proton beam at the Physikalisch Technische Bundesanstalt facility (PTB, Germany), with a Micromegas-based gaseous detector under construction as discussed in the paper. |
