Description
The Nano Imaging Tracker (NIT) is a super-fine-grained nuclear emulsion detector with excellent spatial resolution, capable of reconstructing recoil nucleus directions for track lengths as short as 100 nm, corresponding to energies of several tens of keV. By exploiting hydrogen contained within the NIT itself as a target, we are advancing neutron spectra measurements including the sub-MeV region. This report presents the current status of environmental neutron measurements at the Gran Sasso Laboratory. In addition, we describe the ongoing development of analysis techniques and outline future prospects.
