The wavelengths and energies of thermal and cold neutrons are ideally matched to the length and energy scales in the materials that underpin technologies of the present and future: ranging from semiconductors to magnetic devices, composites to biomaterials and polymers. The Spallation Neutron Source (SNS) will use an accelerator to produce the most intense(More)
The shift of electronics industry towards the use of lead-free solders in components manufacturing brought also the challenge of addressing the problem of tin whiskers. Manufacturers of high reliability and safety critical equipment in sectors such as defence and aerospace rely increasingly on the use of commercial-of-the-shelf (COTS) electronic components(More)
A multiprocessor data acquisition system has been built to replace the single processor systems at the Intense Pulsed Neutron Source (IPNS) at Argonne National Laboratory. The multiprocessor system was needed to accommodate the higher data rates at IPNS brought about by improvements in the source and changes in instrument configurations. This paper(More)
Neutron scattering is a very important tool in the understanding of the structure, dynamics, and magnetic properties of condensed matter, and the performance of neutron scattering instruments is heavily dependent on both the quality and quantity of neutron detectors which can be provided. This paper sets forth those detector characteristics which are(More)
The Intense Pulsed Neutron Source (IPNS) at Argonne National Laboratory is a major new useroriented facility which has come on line for basic research in neutron scattering and neutron radiation damage. This paper describes the distributed processing data acquisition system which handles data collection and instrument control for the time-of-flight neutron(More)
