The first neutron beam was provided to the energy-resolved neutron imaging system, RADEN, of J-PARC in November 2014. Test/demonstration measurements of the resonance absorption imaging carried out so far will be presented. Element enhanced images of copper and zinc in 1- and 2- euro coins, cobalt, manganese and tungsten in a commercially available lithium-ion battery were obtained by the neutron resonance absorption imaging by using a gas electron multiplication (GEM) neutron detector. A test measurement of neutron thermometry was also carried out. Neutron resonances of copper, manganese and platinum were measured at different temperatures by using the GEM neutron detector. Doppler broadenings of the resonances were recognized.
