NOBORU, "NeutrOn Beam- line for Observation and Research Use", is a versatile neutron instrument, which has served a test neutron beam port environment at J-PARC. The NOBORU instrument has been utilized for various purposes such as neutron source characterization, R&Ds on neutron detectors and devices, and testing of new experimental techniques with featuring suitable properties of the pulsed neutron beam. Energy-selective imaging, such as the bragg edge imaging, resonance absorption imaging and magnetic field imaging, is one of important research fields of NOBORU. We have installed a rotary collimator and a remote-controlled neutron filter device in 2009 and 2010, respectively, for the imaging purpose. Due to the upgrading efforts, we believe that NOBORU is now the best pulsed neutron imaging instrument in the world.
