Introduction to Neutron Scattering and ORNL Neutron Facilities
نویسندگان
چکیده
Neutron scattering has been a very powerful probe in the research to the lattice and magnetic structures of various kinds of materials now. In this paper, I will first give a brief introduction of the history of neutron scattering. Then, in the second part, I will talk about the properties of neutron scattering, present its basic mechanism and unique properties. After that, I will give some examples to illustrate the powerful function of neutron scattering in condensed matter physics research. And finally, I will talk a little about some general ways of getting neutrons and neutron facilities in Oak Ridge National Laboratory(ORNL).

Neutron scattering is proved to be a vital probe in unveiling the magnetic properties of high temperature superconductors (HTSC). Detailed information about the energy and momentum dependence of the magnetic dynamics of HTSC have been obtained directly by this technique. Over the past decade by improving the crystal growth methods, large and high quality single crystals of HTSC, which are ess...

متن کاملInvestigation the potential of Boron neutron capture therapy (BNCT) to treat the lung cancer
Introduction: Boron neutron capture therapy (BNCT) is recommended to treat the glioblastoma tumor. It is well known that neuron beams are more effective treatment than photon beams to treat hypoxia tumors due to interaction of neutron with nucleus and production of heavy particles such as 7Li and alpha particle. In this study to evaluate the suitability of BNCT for treating of ...

Background : Performing successful BNCT experiments needs a suitable neutron source. Important factors of the neutron beam are flux and energy that are very important in the selection of neutron source. In most centers that use this method for treatment, reactor is a neutron source, which according to characteristics of the reactor appropriated neutrons are very high. High cost of constructin...
