A Method for Neutron Scattering Quantification and Correction Applied to Neutron Imaging

Simulation of a Neutron Detector for Real Time Imaging Applications

Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...

A Case Study of Computational Diierentiation Applied to Neutron Scattering

In a neutron scattering application, an unconstrained non-linear minimization problem is used for the tting of model parameters to experimental data. Automatic diierentiation enables, in a completely mechanical fashion, algorithmic changes by switching from a quasi-Newton method, where rst order derivatives are approximated by nite diierences, to a modiied Gauss{Newton method using exact rst or...

Introduction to Neutron Scattering

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...

Introduction to Neutron Scattering and ORNL Neutron Facilities

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 exa...
