Recently, we have succeeded in experimentally demonstrating that a series of S(Q,E) maps with multiple incident energies can be simultaneously obtained by one measurement. We are now ready for the breakthrough of scientific activities on non-crystalline materials by making full use of both high neutron flux realized at Japan Proton Accelerator Research Complex (J-PARC) and our novel experimental technique. In this study, some demonstration results on dynamical properties of typical network glass v-SiO, measured by a chopper spectrometer in J-PARC (AMATERAS), will be shown. The applicability and its expected contribution of new experimental technique into the further progress of science will be also discussed.
