BL10 NOBORU NeutrOn Beam-line for Observation and Research Use

Summary

Serving a versatile neutron field for characterizing the neutron source as well as for R&D on various devices, irradiation and analysis of materials, etc

Research ObjectivesCharacterization of the neutron source, nondestructive 3-D imaging of various objects utilizing nature of neutrons as particles, waves and magnets.

NOBORU was constructed at BL10 of the MLF at J-PARC in 2007. The primary mission of NOBORU is facility diagnostics to study neutronic performance of JSNS.

NOBORU also provides a suitable neutron environment for testing various detectors & devices, new ideas for experimental techniques and irradiation of high-energy (~MeV) neutrons.

Ancillary equipment and sample environment
  • Two B4C beam slits to trim the neutron beam (L= 7.1 m & 12.7 m)
  • Flame-overlap chopper (L= 7.2 m)
  • Filter system to attenuate cold neutrons, epithermal neutrons or gamma rays (L= 7.4 m)
  • Rotary-collimator with 4 holes (L= 8.0 m)
  • 5-axis compact goniometer for samples (300 mmφ table; load capacity 20 kg)
Other information for user's convenience
  • Variable collimator ratio (L/D = 140, 190, 600, 1875) for imaging experiments
  • Small beam divergence due to neutron guideless beamline design.
  • Experimental space of 2.5m (W) × 3.5m (L) × 3.0m (H) to introduce various experimental equipment
  • Strong radiation shield that can endure large samples (scattered) up to a 10 cm steel cube
  • Please consult the contact in advance when planning your experimental program
