The Energy-Resolved Neutron Imaging System “RADEN” has been constructed at the beam line of BL22 in the Materials and Life Science Experimental Facility (MLF) of J-PARC. This instrument is the first beam line dedicated for the pulsed neutron imaging experiment in the world. In November 2014, the first neutron beam was delivered to this beam line successfully, and on-beam commissioning study has started. The user programs started partially in 2015. In this paper, we introduce the specifications of our new beam line and present some results of on-beam commissioning and some demonstration study.
