Neutron Beam Facilities

  • Neutron Radiography Facility(NRF), High Resolution Powder Diffractometer(HRPD), Four Circle Neutron Diffractometer(FCD), Residual Stress Instrument(RSI), Vertical Neutron Reflectometer(REF-V), Horizonal Neutron Reflectometer(REF-H), High Intensity Powder Diffractometer(HIPD), Ex-core Neutron Irradiation Facility(ENF) and Prompt Gamma Neutron Activation Analysis system(PGAA) are operating at the HANARO reactor hall. In addition there is a Neutron Activation Analysis system(NAA) consisting of the irradiation facility and the radiation measurement equipment in the HANARO reactor. A 9m SANS instrument installed at CN horizontal port was dismantled and moved to the cold neutron laboratory and currently the cold neutron guide system is installed at CN port area. The Bio-Diffractometer(Bio-D) at ST3 port and Triple Axis Spectrometer(TAS) at ST4 are scheduled to be installed at the reactor hall. Three new cold neutron scattering instruments will be developed and installed in the cold neutron guide hall and three neutron instruments currently existing in the reactor hall will be moved after upgrades. Three new instruments are 40M Small Angle Neutron Scattering Instrument(40M-SANS), Cold Triple Axis Spectrometer(Cold-TAS) and Disk Chopper Time of Flight(DC-TOF) and three upgrade instruments are 12M-SANS, REF-V and Bio-REF.
