This report described recent activities on neutron standardization at the National Metrology Institute of Japan (NMIJ) in the National Institute of Advanced Industrial Science and Technology (AIST). The present status of our accelerator-based neutron field is described mainly on the development of monoenergetic neutron fluence standards [1-3]. Collaboration is in progress with the Japan Atomic ...

Neutron howitzers are routinely used in universities to activate samples for instructional laboratory experiments on radioactivity. They are also a convenient source of neutrons and gammas for research purposes, but they must be used with caution. This paper describes the modeling, design, construction, and testing of a portable, economical shield for a 1.0 Curie neutron howitzer. The Monte Car...

The application of neutron scattering to biological systems using the new neutron source in Munich is discussed. Structural as well as dynamical studies of biomolecules with a variety of spectrometers, diffractometers and reflectometers are explained.

A neutron spectrometer was acquired for use in the measurement of National Institute of Standards and Technology neutron fields. The spectrometer included options for the measurement of low and high energy neutrons, for a total measurement range from 0.01 eV up to 17 MeV. The spectrometer was evaluated in calibration fields and was used to determine the neutron spectrum of an Americium-Berylliu...
