TL;DR: In this paper, the authors present design studies, results of test measurements, and Monte Carlo simulations which served as a basis for the realization of a large area neutron detector (LAND), which has a front area of 2m×2m and a depth of 1 m, and features a multilayer structure of passive converter and active scintillator material.
