Available in PDF, EPUB and Kindle. Book excerpt: Moderator design for pulsed neutron sources is becoming more and more an interface area between source designers and instrument designers. Although there exists a high degree of flexibility, there are also physical and technical limitations. This paper aims at pointing out these limitations and examining ways to extend the current state of moderator technology in order to make the next generation neutron sources even more versatile and flexible tools for science in accordance with the users' requirements.

This book was released on 1999-04-29 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: The applications of the use of cold neutrons for condensed matter research at accelerator-based spallation sources are less well-known than that of the use of cold neutrons at reactor sources. This book represents the outcome of the first international workshop on “Materials Research Using Cold Neutrons at Pulsed Sources”. It consists of overviews of the present status and future trends in research opportunities using cold neutrons, as well as topical papers focusing on the areas of small-angle neutron scattering, reflectivity and spectroscopic studies of a rich variety of materials, from adsorbed molecules to thin films to coal to metallic glasses. These papers will benefit researchers who are interested in the characterization of microscopic properties of advanced materials.

Book excerpt: Moderators using liquid and solid methane and liquid hydrogen are currently in use at major spallation neutron sources. Los Alamos Neutron Scattering Center (LANSCE) is planning the use of liquid methane as part of a major update program planned in about three years time. This report presents a general overview of some of these devices and outlines the general engineering design of the proposed LANSCE moderator, including some suggested solutions to the radiation damage problems of methane. Also included is a brief overview of a possible combined H2/Ch4 moderator for high intensity proton beams. 15 figs.

Book excerpt: The working group meeting was chaired by Bauer and Lucas. Testing is a vital part of any cold source development project. This applies to specific physics concept verification, benchmarking in conjunction with computer modeling and engineering testing to confirm the functional viability of a proposed system. Irradiation testing of materials will always be needed to continuously extend a comprehensive and reliable information database. An ever increasing worldwide effort to enhance the performance of reactor and accelerator based neutron sources, coupled with the complexity and rising cost of building new generation facilities, gives a new dimension to cold source development and testing programs. A stronger focus is now being placed on the fine-tuning of cold source design to maximize its effectiveness in fully exploiting the facility. In this context, pulsed spallation neutron sources pose an extra challenge due to requirements regarding pulse width and shape which result from a large variety of different instrument concepts. The working group reviewed these requirements in terms of their consequences on the needs for testing equipment and compiled a list of existing and proposed facilities suitable to carry out the necessary development work.
Book Synopsis Simulation of Cold Neutron Production Using Ordinary and Deuterated Cryogenic Organic Moderators by : Martin Luc Niset

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis is to investigate the use of deuterated organic moderator to produce cold neutron in a reactor based cold neutron source. This is of interest for two reasons: first, for possible enhancement of the operation of the Texas Cold Neutron Source located at the TRIGA reactor of the Nuclear Engineering Teaching Laboratory at the University of Texas; second, for the design of an Ultracold Neutron Source. Two computer codes were used to achieve this objective: NJOY 97 to generate the necessary thermal scattering cross sections; MCNP 4B to simulate the thermalization and transport of the neutrons in the Texas Cold Neutron Source. The generation of thermal neutron cross sections from neutron scattering laws by NJOY was intensively studied for methane (CH4) at 22K. The influence of several key physical and numerical parameters of the input file were investigated. The results obtained gave a good understanding on how to generate the cross section in the best capability of the code NJOY. The calculated scattering cross sections were then tested by MCNP to match an experiment performed by Utsuro (1975). Although the experiment was done with a different organic moderator, 1,3,5-trimethylbenzene (mesithylene), the effects associated to the three methyl radicals should be present in the case of methane. The results of this study gave confidence that the cross sections generated by NJOY match rather well the physical cross section of organic materials. Finally, using thermal cross section for methane and deuterated methane generated by NJOY, the performance of the Texas Cold Neutron Source was simulated using MCNP under a variety of conditions. The incident thermal neutron flux coming from the core of the TRIGA reactor at NETL was simulated. Moderation of these neutrons takes place in the TCNS chamber and cold neutrons entering the neutron guide were tallied. The effect of mixing ordinary and deuterated moderators was determined

Book Synopsis A Modular Approach to the Design of Cold Moderators by :
Download or read book A Modular Approach to the Design of Cold Moderators written by and published by . This book was released on 1998 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cold moderators are usually designed to the specific requirements of the parent neutron source. However since all cryogenic moderators within a broad design envelope require certain common parameters, it should be possible to create a central core design served by smaller packages designed, or selected to satisfy a wide range of individual requirements. This paper describes a modular design philosophy that has been applied to two very different cold sources with only minor changes to two of the modules in the system. Both of the systems and the basic differences between them are described in detail.
