Application of neutron shield concrete to neutron scattering instrument TAIKAN in J-PARC

Application of Neutron Scattering in Earth Sciences

The unique properties of neutron interaction with materials have long been applied to the study of geological materials, with Shull and Smart using them in 1949 to determine the antiferromagnetic structure of manganosite (MnO). Neutron diffraction provides an accurate method for crystal structure determination of hydrous phases, particularly ices, and investigations of cation ordering of elemen...

Using Zirconium Borohydride as Neutron Shield in LINAC head

Introduction: One of the concerns about using of high energy photons in radiotherapy is neutron contamination production. The threshold energy of photoneutron production in most materials with high atomic number is about 7MeV. Therefore, it seems to be logical that the main components with high atomic number elements used in the LINAC head have a large contribution to the neutr...

Estimation of neutron effective dose from DD and DT neutron generators and the design of appropriate shield for standing user

Neutron Generators (NG) are used as a neutron source for different applications. During recent years, major efforts are underway to develop a high yield compact NG. In this way, radiation protection aspects need to be considered during the operation of these high yield NGs. In this paper the neutron effective dose of a NG operator has been calculated using MCNPX Monte Carlo code. The results sh...

Introduction to Neutron Scattering

Neutron scattering is a powerful and direct means for investigating the vibrational, magnetic, and structural properties of materials. In this paper, I will present a brief introduction to neutron scattering. I will discuss why neutrons are important, how and where you get neutrons, and types of neutron scattering. This paper is meant as brief introduction into an interesting field of science t...
