The Energy-resolved neutron imaging system, RADEN, has been constructed in J-PARC MLF in 2014 and started the user operation in 2015. This instrument was designed to enable the energy-resolved neutron imaging experiments, such as Bragg edge imaging and neutron resonance imaging to visualize spatial distributions of crystallographic information and elemental information respectively. To realize excellent performance for these experiments, it was installed at the beamline of BL22. In addition, as the results of continuous developments on energy-resolved neutron imaging techniques using time-of-flight (TOF) analysis and on the related devices, the polarimetric neutron imaging and the neutron imaging with the grating interferometry became available in combination with wavelength/energy analysis. Accordingly, RADEN becomes a quite unique instrument in the world that can offer opportunities of conducting almost all energy-resolved neutron imaging experiments.
