Setup fitting the requirements for the detailed study of the five-body decay of the H-7 nucleus obtained as a result of the proton transfer from the He-8 projectiles to the deuterium target nuclei is being built at the radioactive beam line of ACCULINNA-2 separator in the G.N. Flerov Laboratory of Nuclear Reactions. Described here is the assembly of 100 BC-404 plastic scintillators, intended for neutron detection, the annular Si detector telescope for the He-3 recoils, and the detector array providing the & UDelta;E-E-TOF registration of H-3 nuclei emitted at the H-7 decay. Results obtained by the Monte Carlo simulations made for the energy values and flight passes of all these particles are given together with the luminosity expected for the discussed experiments.
