ACCULINNA-2 facility, FLNR, JINR, produced 26\,AMeV $^{8}$He and focused it on the cryogenic deuterium target.
The experiment was dedicated to $^{7}$H studies, see Ref.\ \cite{Muzalevskii:2021}, but the detection system allowed to measure the product of the $^2$H($^8$He,$^6$Li)4n reaction and further neutron decay.
ACCULINNA-2 facility, FLNR, JINR, produced the 26\,AMeV $^{8}$He beam with intensity $\approx10^{5}$\,pps.
This beam was focused on the cryogenic gaseous deuterium 27\,K target with a temperature of 27\,K equipped with stainless steel and mylar windows.
Initially, the experiment was dedicated to $^{7}$H studies, see Ref.\ \cite{Muzalevskii:2021}, but the detection system allowed to measure the product of the $^2$H($^8$He,$^6$Li)4n reaction and further neutron decay.
The employed detector system is widely described in Ref.\ \cite{Muzalevskii:2021}.

The beam particles were identified by two plastic scintillators, which allowed to measure the energy of the projectile from its time-of-flight (ToF).

The cryogenic target was filled with a deuterium gas at 27\,K of atmospheric pressure.
The special run with the empty target cell was conducted to estimate the background conditions, which had $\approx$16\% of the total $^8$He beam time.
